The Bold Ones in the Land of Strange
PHYSICS OF THE IMPOSSIBLE: The Bold Ones in the Land of Strange By Karol Jałochowski. Translation by Kamila Slawinska. Originally published in POLITYKA 41, 85 (2010) in Polish. A new scientific center has just opened at Singapore’s Science Drive 2: its efforts are focused on revealing nature’s uttermost secrets. The place attracts many young, talented and eccentric physicists, among them some Poles. This summer night is as hot as any other night in the equatorial Singapore (December ones included). Five men, seated at a table in one of the city’s countless bars, are about to finish another pitcher of local beer. They are Artur Ekert, a Polish-born cryptologist and a Research Fellow at Merton College at the University of Oxford (profiled in issue 27 of POLITYKA); Leong Chuan Kwek, a Singapore native; Briton Hugo Cable; Brazilian Marcelo Franca Santos; and Björn Hessmo of Sweden. While enjoying their drinks, they are also trying to find a trace of comprehensive tactics in the chaotic mess of ball-kicking they are watching on a plasma screen above: a soccer game played somewhere halfway across the world. “My father always wanted me to become a soccer player. And I have failed him so miserably,” says Hessmo. His words are met with a nod of understanding. So far, the game has provided the men with no excitement. Their faces finally light up with joy only when the score table is displayed with the results of Round One of the ongoing tournament. Zeros and ones – that’s exciting! All of them are quantum information physicists: zeroes and ones is what they do. -

Constraint Based Dimension Correlation and Distance
Preface The papers in this volume were presented at the Fourteenth Annual IEEE Conference on Computational Complexity held from May 4-6, 1999 in Atlanta, Georgia, in conjunction with the Federated Computing Research Conference. This conference was sponsored by the IEEE Computer Society Technical Committee on Mathematical Foundations of Computing, in cooperation with the ACM SIGACT (The special interest group on Algorithms and Complexity Theory) and EATCS (The European Association for Theoretical Computer Science). The call for papers sought original research papers in all areas of computational complexity. A total of 70 papers were submitted for consideration of which 28 papers were accepted for the conference and for inclusion in these proceedings. Six of these papers were accepted to a joint STOC/Complexity session. For these papers the full conference paper appears in the STOC proceedings and a one-page summary appears in these proceedings. The program committee invited two distinguished researchers in computational complexity - Avi Wigderson and Jin-Yi Cai - to present invited talks. These proceedings contain survey articles based on their talks. The program committee thanks Pradyut Shah and Marcus Schaefer for their organizational and computer help, Steve Tate and the SIGACT Electronic Publishing Board for the use and help of the electronic submissions server, Peter Shor and Mike Saks for the electronic conference meeting software and Danielle Martin of the IEEE for editing this volume. The committee would also like to thank the following people for their help in reviewing the papers: E. Allender, V. Arvind, M. Ajtai, A. Ambainis, G. Barequet, S. Baumer, A. Berthiaume, S. -
Inter Actions Department of Physics 2015
INTER ACTIONS DEPARTMENT OF PHYSICS 2015 The Department of Physics has a very accomplished family of alumni. In this issue we begin to recognize just a few of them with stories submitted by graduates from each of the decades since 1950. We want to invite all of you to renew and strengthen your ties to our department. We would love to hear from you, telling us what you are doing and commenting on how the department has helped in your career and life. Alumna returns to the Physics Department to Implement New MCS Core Education When I heard that the Department of Physics needed a hand implementing the new MCS Core Curriculum, I couldn’t imagine a better fit. Not only did it provide an opportunity to return to my hometown, but Carnegie Mellon itself had been a fixture in my life for many years, from taking classes as a high school student to teaching after graduation. I was thrilled to have the chance to return. I graduated from Carnegie Mellon in 2008, with a B.S. in physics and a B.A. in Japanese. Afterwards, I continued to teach at CMARC’s Summer Academy for Math and Science during the summers while studying down the street at the University of Pittsburgh. In 2010, I earned my M.A. in East Asian Studies there based on my research into how cultural differences between Japan and America have helped shape their respective robotics industries. After receiving my master’s degree and spending a summer studying in Japan, I taught for Kaplan as graduate faculty for a year before joining the Department of Physics at Cornell University. -
Lecture 12: Quantum Key Distribution. Secret Key. BB84, E91 and B92 Protocols. Continuous-Variable Protocols. 1. Secret Key. A
Lecture 12: Quantum key distribution. Secret key. BB84, E91 and B92 protocols. Continuous-variable protocols. 1. Secret key. According to the Vernam theorem, any message (for instance, consisting of binary symbols, 01010101010101), can be encoded in an absolutely secret way if the one uses a secret key of the same length. A key is also a sequence, for instance, 01110001010001. The encoding is done by adding the message and the key modulo 2: 00100100000100. The one who knows the key can decode the encoded message by adding the key to the message modulo 2. The important thing is that the key should be used only once. It is exactly this way that classical cryptography works. Therefore the only task of quantum cryptography is to distribute the secret key between just two users (conventionally called Alice and Bob). This is Quantum Key Distribution (QKD). 2. BB84 protocol, proposed in 1984 by Bennett and Brassard – that’s where the name comes from. The idea is to encode every bit of the secret key into the polarization state of a single photon. Because the polarization state of a single photon cannot be measured without destroying this photon, this information will be ‘fragile’ and not available to the eavesdropper. Any eavesdropper (called Eve) will have to detect the photon, and then she will either reveal herself or will have to re-send this photon. But then she will inevitably send a photon with a wrong polarization state. This will lead to errors, and again the eavesdropper will reveal herself. The protocol then runs as follows.
