Demonstration of an Active Quantum Key Distribution Network

August 1, 2006
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Hai Xu, Barry J. Hershman, Joshua Bienfang, David H. Su, Ronald Boisvert, Charles W. Clark, Carl J. Williams
We previously demonstrated a high speed, point to point, quantum key distribution (QKD) system with polariztion coding over a fiber link, in which the resulting cryptographic keys were used for one-time pad encryption of real time video signals. In this

Quantum Key Distribution System Operating at Sifted-Key Rate over 4 Mbit/s

Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Hai Xu, Barry J. Hershman, Joshua Bienfang, David H. Su, Ronald Boisvert, Charles W. Clark, Carl J. Williams
A complete fiber-based polarization encoding quantum key distribution (QKD) system based on the BB84 protocol has been developed at National Institute of Standard and Technology (NIST). The system can be operated at a sifted key rate of more than 4 Mbit/s

High Speed Quantum Key Distribution System Supports One-Time Pad Encryption of Real-Time Video

Author(s)
Alan Mink, Xiao Tang, Lijun Ma, Anastase Nakassis, Barry J. Hershman, Joshua C. Bienfang, David H. Su, Ronald F. Boisvert, Charles W. Clark, Carl J. Williams
NIST has developed a high-speed quantum key distribution (QKD) test bed incorporating both free-space and fiber systems. These systems demonstrate a major increase in the attainable rate of QKD systems: over two orders of magnitude faster than other

Is Quantum Cryptography Provably Secure?

April 1, 2006
Author(s)
Anastase Nakassis, Joshua Bienfang, P. Johnson, Alan Mink, D. Rogers, Xiao Tang, Carl J. Williams
Quantum cryptography asserts that shared secrets can be established over public channels in such a way that the total information of an eavesdropper can be made arbitrarily small with probability arbitrarily close to 1. As we will show below, the current

High Speed Fiber-Based Quantum Key Distribution using Polarization Encoding

October 5, 2005
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Barry J. Hershman, Joshua Bienfang, Ronald Boisvert, Charles W. Clark, Carl J. Williams, A Gross, E Hagley, J Wen
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

High Speed Fiber-Based Quantum Key Distribution Using Polarization Encoding

Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Barry J. Hershman, J Bienfan, Ronald Boisvert, Charles W. Clark, Carl J. Williams
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

Multimodal Biometric Authentication Methods: A COTS Approach

December 1, 2003
Author(s)
Michael D. Indovina, Robert D. Snelick, Alan Mink
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometrics on a population approaching 1000 individuals. Prior studies of multimodal biometrics have been

Multimodal Biometrics: Issues in Design and Testing

November 1, 2003
Author(s)
Robert D. Snelick, Michael D. Indovina, James H. Yen, Alan Mink
The results of experimental studies on multimodal biometric systems for small-scale populations have shown better performance compared to single-mode biometric systems. We examine if such techniques scale to larger populations, introduce a methodology to

High-Speed Quantum Communication Testbed

December 1, 2002
Author(s)
Carl J. Williams, Xiao Tang, M Hiekkero, J Rouzard, R Lu, A Goedecke, Alan L. Migdall, Alan Mink, Anastase Nakassis, Leticia S. Pibida
We describe the current status of the NIST Quantum Communication Testbed (QCT) facility. QCT is a facility for exploring quantum communication in an enviornment similar to that projected for early commercial implementations: quantum cryptographic key

A Performance Measurement Environment for Cluster Computing

August 1, 2000
Author(s)
M M. Courson, Alan Mink, G J. Marcais, B Traverse
A number of factors promote frequent running of performance measurement codes for the evaluation and tuning of both applications and platforms. NIST is developing a prototype for an automated software measurement toolset to reduce the manual effort in
