CMC Citation for 2020 Micius Quantum Prize (Theory Portion)
The Sun rises in Albuquerque on December 10, 2020, as the Prize is announced in Beijing. CMC citation for 2020 Micius Quantum Prize (theory portion) For foundational work on quantum metrology and quantum information theory, especially for elucidating the fundamental noise in interferometers and its suppression with the use of squeezed states. CMC remarks at the press conference announcing award of the Prize First, thanks to the Micius Foundation for awarding me this prestigious, international research prize. The prize is aptly named for the ancient Chinese philosopher Micius, whose moral teachings emphasized introspection, self-reflection, and authenticity, all values that I hold dear, and who taught that all people are equal and that innovation is as valuable as tradition. Second, thanks to the Selection Committee. That this group of outstanding scientists thought that my scientific contributions are worthy of recognition is both gratifying and humbling. Third, thanks to Peter Zoller for a very favorable rendering of my contributions to science. I can only wonder where Peter was back when I was trying to get the University of New Mexico to raise my salary. It is a great honor to have been awarded a prize of this magnitude and prestige. But prizes are dangerous. The head swells, and it needs to be deflated, and for deflation, I have my two kids, Eleanor Caves and Jeremy Rugenstein, both of whom are scientists, as are their spouses. I happened to open the e-mail informing me I had been awarded the Micius Prize on a Saturday morning a few weeks ago, just as I was about to Skype with Eleanor in the UK and Jeremy in Colorado. -
Making Quantum Technology Ready for Industry
Brussels 28/29 March 2019 Making Quantum Technology ready for Industry Putting Science Into Standards (PSIS) Workshop on Quantum Technology CEN-CENELEC Management Centre Rue de la Science 23, 1040-Brussels www.cencenelec.eu www.ec.europa.eu/jrc/en #Standards4Quantum Workshop structure On 28th and 29th of March 2019, the Joint Research Centre and CEN/CENELEC hold at the CEN/ CENELEC Management Centre (CCMC) in rue de la Science 23, Brussels, a workshop titled Making Quantum Technology Ready for Industry. The workshop focuses on current standards and potential standardisation fields in quantum technologies and is organised with the support of the German Institute for Standardization (DIN) and DG CNECT, the host of the EU Quantum Flagship. In Europe, the European Telecommunications Standards Institute (ETSI) has established an Industry Specification Group with a specific focus on quantum key distribution (QKD). At the international level, standardization is taking place within Joint Technical Committee 1 of ISO/IEC addressing among others cybersecurity and data protection. CEN and CENELEC have signed agreements with ISO and IEC through which common European and international standards can be developed in parallel, thereby avoiding duplication of work Since many quantum technology areas are advancing on the technology readiness level scale, it is important to prepare the field for standardization activities, helping to facilitate and accelerate market uptake of quantum technology. The workshop provides: 1. an overview of how standardization can be useful to the quantum innovation process; 2. what standardizers can do for the quantum science community. To contribute to the different pace in the main quantum areas, the workshop is divided in four technical sessions. -

Single Ion Addressing of up to 50 Ions
Single Ion Addressing of up to 50 Ions A master's thesis submitted to the Faculty of Mathematics, Computer Science and Physics of the Leopold-Franzens University of Innsbruck in partial fulfilment of the requirements for the degree of Master of Science (MSc.) presented by Lukas Falko Pernthaler supervised by o.Univ.-Prof. Dr. Rainer Blatt and Dr. Christian F. Roos carried out at the Institute for Quantumoptics and Quantuminformation (IQOQI) August 2019 dedicated to my parents 2 Abstract Quantum computers are believed to revolutionize the way of solving problems classical computers aren't able to. Related to the universal quantum computer, which can be programmed as wished, is the quantum simulator, which can be initialized with a certain problem or also only a single task of a greater problem. The problem is solved by evolving and measuring the state of the used qubits. My work deals with a quantum simulator using linear chains of 40Ca+ ions in a Paul trap. An optical setup was designed using the ZEMAX software to obtain an addressing range of more than 230 µm along with a spot size on the order of 2 µm for a 729 nm laser. This is achieved using an acousto-optical deflector (AOD) and an optical setup, which projects the output of the AOD on the focussing objective, while enlarging the laser beam at the same time. The system was characterized first in a test setup by putting a small-pixelsized CCD camera in the focal plane of the objective. Then, the old addressing system was replaced by the new one, allowing the addressability of 51 ions with comparable spot size of the 729 nm laser relative to the old setup. -

Zu den Highlights zählten zweifelsohne die Jahrestagung der World Academy of Sciences mit Teilnehmerinnen und Teilnehmern aus über 60 Ländern sowie – für mich persönlich – mein Besuch beim CeMM gemeinsam mit dem Staatspräsidenten der Italienischen Republik, Sergio Matarella. Darüber hinaus stellt der Start der Initiative „Genom Austria“, über die meine Frau den Ehrenschutz übernommen hat, ein wegweisendes Projekt dar, in dem ganz konkret die gesellschaftliche Bedeutung der modernen Genetik und ihrer Möglichkeiten untersucht werden soll. Exemplarisch wird damit die Foto: Ingo Pertramer Notwendigkeit aufgezeigt, die naturwissenschaftlich-technische Entwicklung mit der Öffentlichkeit zu diskutieren, Transparenz und Mündigkeit zu stärken und so eine auf Wissen gründende Partizipation an heutiger Spitzenforschung zu ermöglichen. Ich erwähne dieses Beispiel von „Genom Austria“ auch deshalb, weil an ihm deutlich wird, in welchem hohen Maße sich die Österreichische Akademie der Wissenschaften als Ort der Wissenschaft und als Ort des gesellschaftlichen Diskurses versteht. Dafür möchte ich allen Beteiligten danken. -

Andrew Steane Andrew Steane is Professor of Physics at the Center for Quantum Computation, Atomic and Laser Physics, University of Oxford, England and Tutorial Fellow of Exeter College. His main fields of research activity are: experimental quantum optics, especially laser cooling and trapped ions, theoretical quantum information, especially quantum error correction. Participation in EC projects: QUBITS, QUEST, CONQUEST, QGATES, SCALA; national projects: QIPIRC. Andrew Steane received the Maxwell Medal of the Institute of Physics (2000). Abstract Strings of atomic ions confined in an electromagnetic field configuration, so-called ion traps, serve as carriers of quantum information. With the use of lasers and optical control techniques, quantum information processing with trapped ions was demonstrated during the 1 last few years. The technology is inherently scalable to larger devices and appears very promising for an implementation of quantum processors. Introduction The use of strings of trapped ions in electromagnetic traps, so-called Paul traps, provides a very promising route towards scalable quantum information processing. There are ongoing investigations in several laboratories whose direction is towards implementing a quantum computer based on this technique. In the following, the methods will be briefly described and the state-of-the-art will be highlighted with some of the latest experimental results. -
