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

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

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

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

Java

July 1, 2005
Author(s)
Ronald F. Boisvert, Roldan Pozo
Our goal here is to provide to non-Java programmers some guidance as to whether Java might be appropriate for scientific applications. We will discuss some of Java's features which promote the safety, reliability, and portability, and then briefly address

Mathematical Software: Past, Present, and Future

March 1, 2002
Author(s)
Ronald F. Boisvert
This paper provides some reflections on the field of mathematical software on the occasion of John Rice's 65th birthday. We describe some of the common themes of research in this field and recall some significant events in its evolution. Finally, we raise

Java and Numerical Computing

April 1, 2001
Author(s)
Ronald F. Boisvert, J Moreira, M Philippsen, Roldan Pozo
We discuss the advantages and disadvantages of using Java for numerical computing. We provide examples of current performance levels and propose several additional language features that would make Java more easily applied in scientific applications.

Mathematics and Measurement

Author(s)
Ronald F. Boisvert, Michael J. Donahue, Daniel W. Lozier, Robert D. McMichael, Bert W. Rust
In this paper we describe the role that mathematics plays in measurement science at NIST. We first survey the history behind NIST's current work in this area, starting with the NBS Math Tables project of the 1930s. We then provide examples of more recent
