It is devoted to finding methods to exploit quantum mechanical effects in nature, notably superposition and entan- glement, to perform information processing beyond the limits of conventional computation. Over the past several decades, various research groups around the world have strived to achieve the ambitious goal of building a quantum computer that could dramatically improve computational power for particular tasks. Responding to the growing need to extract information from images and video, image processing is a fundamental task in many branches of science and engineering. Due to the restricted architecture of classical computers and the com- putational complexity of state-of-the-art classical algorithms in image processing and its applications, developing efficient algorithms to store and manipulate visual information has become an important and challenging research area. Quantum image processing focuses on quantum algorithms for storing, process- ing, and retrieving visual information. Due to some of the astounding properties inherent to quantum information, for instance, computational parallelism, it is anticipated that quantum image processing technologies will offer capabilities and performance that are currently unrivaled by their traditional equivalents in areas such as computing speed, tamperproof security, and minimal storage requirements. This book is divided into seven chapters. In Chap. 1, the key fundamentals of quantum computation and information are reviewed, and the history of quantum image processing is introduced. The widely used quantum image representations and their well-designed operations are presented in Chaps. 2 and 3. The outline of quantum image security technologies and a few quantum image understanding algorithms are suggested in Chaps. 4 and 5. The two emerging subtopics of quantum movies and quantum audio are elaborated in Chap. 6. Chapter 7 discusses open questions identified in the literature, along with future development trends in quantum image processing. It is hoped that this book offers a rigorous introduction to quantum image processing and some thought-provoking snapshots of prospective developments. The completion of this book relied greatly on the research achievements published v vi Preface in the field and the two bibles: Quantum Computation and Quantum Information (Michael A. Nielsen et al.) and Digital Image Processing (Rafael C. Gonzalez et al.).

Quantum spectral analysis: frequency at time Mario Mastriani Quantum Communications Group, Merxcomm LLC, 2875 NE 191 st, suite 801, Aventura, FL 33180, USA [email protected] Abstract A quantum time-dependent spectrum analysis, or simply, quantum spectral analysis (QuSA) is presented in this work, and it’s based on Schrödinger equation, which is a partial differential equation that describes how the quantum state of a non-relativistic physical system changes with time. In classic world is named frequency at time (FAT), which is presented here in opposition and as a complement of traditional spectral analysis frequency-dependent based on Fourier theory. Besides, FAT is a metric, which assesses the impact of the flanks of a signal on its frequency spectrum, which is not taken into account by Fourier theory and even less in real time.

    Noname manuscript No. (will be inserted by the editor) A Critical and Moving-Forward View on Quantum Image Processing Fei Yan · Salvador E. Venegas-Andraca · Kaoru Hirota Received: date / Accepted: date Physics and computer science have a long tradition of cross-fertilization. One of the latest outcomes of this mutually beneficial relationship is quan- tum information science, which comprises the study of information processing tasks that can be accomplished using quantum mechanical systems [1]. Quan- tum Image Processing (QIMP) is an emergent field of quantum information science whose main goal is to strengthen our capacity for storing, processing, and retrieving visual information from images and video either by transition- ing from digital to quantum paradigms or by complementing digital imaging with quantum techniques. The expectation is that harnessing the properties of quantum mechanical systems in QIMP will result in the realization of ad- vanced technologies that will outperform, enhance or complement existing and upcoming digital technologies for image and video processing tasks. QIMP has become a popular area of quantum research due to the ubiquity and primacy of digital image and video processing in modern life [2]. Digital image processing is a key component of several branches of applied computer science and engineering like computer vision and pattern recognition, disci- plines that have had a tremendous scientific, technological and commercial success due to their widespread applications in many fields like medicine [3,4], military technology [5,6] and the entertaining industry [7,8]. The technologi- cal and commercial success of digital image processing in contemporary (both civil and military) life is a most powerful incentive for working on QIMP.

  • Traceable Quantum Steganography Scheme Based on Pixel Value Diferencing Jia Luo1,2, Ri-Gui Zhou1,2*, Gaofeng Luo1,2,3, Yaochong Li1,2 & Guangzhong Liu1*
    www.nature.com/scientificreports OPEN Traceable Quantum Steganography Scheme Based on Pixel Value Diferencing Jia Luo1,2, Ri-Gui Zhou1,2*, GaoFeng Luo1,2,3, YaoChong Li1,2 & GuangZhong Liu1* A novel and traceable quantum steganography scheme based on pixel value diferencing (PVD) is proposed. In the proposed scheme, a quantum cover image is divided into non-overlapping blocks of two consecutive pixels. Then, by a series of reversible logic circuits, we calculate the diference value based on the values of the two pixels in each block and classify it as one of a set of continuous ranges. The secret image and operator information are embedded in the cover image by using the new obtained diference value to replace the original one. The number of bits of secret image that can be embedded in a block is determined, and the number of bits of operator information is decided by the range of the diference value belongs to. Moreover, when the embedded data is extracted from a stego image, it is not necessary to refer to the original cover image. The performance of the proposed scheme is based on the analysis of several categories of simulation results, such as visual quality, capacity, and robustness. In recent decades, an increasing number of researchers have invested in the feld of quantum image processing. Firstly, Vlasov1 proposed a method of recognizing orthogonal images. Later, G. Beach et al.2 showed that quantum algorithms like Grover algorithm3 can be used for image processing tasks. And then, the investigations about capturing and storing digital image on a quantum computer were explored.

  • Quantum Image Processing: the Truth, the Whole Truth, and Nothing but the Truth About Its Problems on Internal Image- Representation and Outcomes Recovering
    Quantum Image Processing: the truth, the whole truth, and nothing but the truth about its problems on internal image- representation and outcomes recovering Mario Mastriani ORCID Id: 0000-0002-5627-3935 Qubit Reset LLC, 2875 NE 191, suite 801, Aventura, FL 33180, USA [email protected] Abstract – In this paper, three tecniques of internal image-representation in a quantum computer are compared: Flexible Representation of Quantum Images (FRQI), Novel Enhanced Quantum Represen- tation of digital images (NEQR), and Quantum Boolean Image Processing (QBIP). All conspicuous technical items are considered in this comparison for a complete analysis: i) performance as Classical- to-Quantum (Cl2Qu) interface, ii) characteristics of the employed qubits, iii) sparsity of the used internal registers, iv) number and size of the required registers, v) quality in the outcomes recovering, vi) number of required gates and its consequent accumulated noise, vi) decoherence, and vii) fidelity. These analyses and demonstrations are automatically extended to all variants of FRQI and NEQR. This study demonstrated the practical infeasibility in the implementation of FRQI and NEQR on a physical quantum computer (QPU), while QBIP has proven to be extremely successful on: a) the four main quantum simulators on the cloud, b) two QPUs, and c) optical circuits from three labs. Moreover, QBIP also demonstrated its economy regarding the required resources needed for its proper function and its great robustness (immunity to noise), among other advantages, in fact, without any exceptions. Keywords: Classical-to-Quantum Interface; Flexible Representation of Quantum Images; Novel Enhanced Quantum Representation of digital images; Physical quantum computer; Quantum Boolean Image Processing; Quantum Image Processing.

  • Optimal Estimation of States in Quantum Image Processing
    Quantum image processing? Mario Mastriani DLQS LLC, 4431 NW 63RD Drive, Coconut Creek, FL 33073, USA [email protected] Abstract—This paper presents a number of problems concerning the practical (real) implementation of the techniques known as Quantum Image Processing. The most serious problem is the recovery of the outcomes after the quantum measurement, which will be demonstrated in this work that is equivalent to a noise measurement, and it is not considered in the literature on the subject. It is noteworthy that this is due to several factors: 1) a classical algorithm that uses Dirac’s notation and then it is coded in MATLAB does not constitute a quantum algorithm, 2) the literature emphasizes the internal representation of the image but says nothing about the classical-to-quantum and quantum-to-classical interfaces and how these are affected by decoherence, 3) the literature does not mention how to implement in a practical way (at the laboratory) these proposals internal representations, 4) given that Quantum Image Processing works with generic qubits this requires measurements in all axes of the Bloch sphere, logically, and 5) among others. In return, the technique known as Quantum Boolean Image Processing is mentioned, which works with computational basis states (CBS), exclusively. This methodology allows us to avoid the problem of quantum measurement, which alters the results of the measured except in the case of CBS. Said so far is extended to quantum algorithms outside image processing too. Keywords—Quantum algorithms – Quantum Boolean Image Processing - Quantum/Classical Interfaces – Quantum image processing - Quantum measurement - Quantum signal processing.

  • Quantum Boolean Image Denoising
    Quantum Boolean Image Denoising Mario Mastriani DLQS LLC, 4431 NW 63RD Drive, Coconut Creek, FL 33073, USA. [email protected] Abstract —A quantum Boolean image processing methodology is presented in this work, with special emphasis in image denoising. A new approach for internal image representation is outlined together with two new interfaces: classical-to-quantum and quantum-to-classical. The new quantum-Boolean image denoising called quantum Boolean mean filter (QBMF) works with computational basis states (CBS), exclusively. To achieve this, we first decompose the image into its three color components, i.e., red, green and blue. Then, we get the bitplanes for each color, e.g., 8 bits-per-pixel, i.e., 8 bitplanes-per-color. From now on, we will work with the bitplane corresponding to the most significant bit (MSB) of each color, exclusive manner. After a classical-to-quantum interface (which includes a classical inverter), we have a quantum Boolean version of the image within the quantum machine. This methodology allows us to avoid the problem of quantum measurement, which alters the results of the measured except in the case of CBS. Said so far is extended to quantum algorithms outside image processing too. After filtering of the inverted version of MSB (inside quantum machine) the result passes through a quantum-classical interface (which involves another classical inverter) and then proceeds to reassemble each color component and finally the ending filtered image. Finally, we discuss the more appropriate metrics for image denoising in a set of experimental results. Keywords —Quantum algorithms - Quantum-Boolean Image Denoising - Quantum/Classical Interfaces - Quantum measurement.

    Quantum Edge Detection for Image Segmentation in Optical Environments Mario Mastriani DLQS LLC, 4431 NW 63RD Drive, Coconut Creek, FL 33073, USA. [email protected] Abstract—A quantum edge detector for image segmentation in optical environments is presented in this work. A Boolean version of the same detector is presented too. The quantum version of the new edge detector works with computational basis states, exclusively. This way, we can easily avoid the problem of quantum measurement retrieving the result of applying the new detector on the image. Besides, a new criterion and logic based on projections onto vertical axis of Bloch’s Sphere exclusively are presented too. This approach will allow us: 1) a simpler development of logic quantum operations, where they will closer to those used in the classical logic operations, 2) building simple and robust classical-to-quantum and quantum- to-classical interfaces. Said so far is extended to quantum algorithms outside image processing too. In a special section on metric and simulations, a new metric based on the comparison between the classical and quantum versions algorithms for edge detection of images is presented. Notable differences between the results of classical and quantum versions of such algorithms (outside and inside of quantum computer, respectively) show the existence of implementation problems involved in the experiment, and that they have not been properly modeled for optical environments. However, although they are different, the quantum results are equally valid. The latter is clearly seen in the computer simulations. Keywords—Quantum algorithms - Quantum edge detection – Image segmentation - Quantum/Classical Interfaces - Quantum measurement.

To improve the concealment of steganographic embedding of secret messages and enhance embedding capacity, the present study proposed a quantum red-green-blue (RGB) image steganography based on image block and gray level difference. First, digital color images were represented by quantum models and divided into non-overlapping blocks. Second, reference pixels in the blocks were selected, and gray level difference between the reference pixels and the G channel of other pixels was calculated. Third, according to the location of the difference, different bit planes where secret messages were embedded into the R and the B channels of the carrier image were determined. Finally, steganographic image was divided into blocks. The G channel gray difference was calculated, and the original secret message was extracted. Results demonstrate that quantum RGB image steganography has a steganographic capacity of four bits per pixel, and its quantum circuit is less complex. In comparison with other quantum image steganographic methods, the proposed method ensures a large steganographic capacity while realizing satisfactory visual quality and steganographic concealment.

It is precisely in Quantum Cryptography where two techniques stand out above all others: Quantum key Distribution (QKD), and Quantum Secure Direct Communication (QSDC). The first one has four loopholes relating to the exposure of the key at all points in the communication system, while the second has clear practical implementation problems in all its variants currently in use. Here, we present an alternative to QKD and QSDC techniques called quantum key secure communication (QKSC) protocol with a successful implementation on two free access quantum platforms.

Knuth Received: 28 June 2014; in revised form: 21 August 2014 / Accepted: 29 August 2014 / Published: 10 October 2014 Abstract: A flexible representation of quantum images (FRQI) was proposed to facilitate the extension of classical (non-quantum)-like image processing applications to the quantum computing domain. The representation encodes a quantum image in the form of a normalized state, which captures information about colors and their corresponding positions in the images. Since its conception, a handful of processing transformations have been formulated, among which are the geometric transformations on quantum images (GTQI) and the CTQI that are focused on the color information of the images. In addition, extensions and applications of FRQI representation, such as multi-channel representation for quantum images (MCQI), quantum image data searching, watermarking strategies for quantum images, a framework to produce movies on quantum computers and a blueprint for quantum video encryption and decryption have also been suggested.
