What is Quantum
Information?
The Beginning of Quantum Information at NIST
The starting point for quantum
information at NIST was in 1995 when the
Ion Storage Group
demonstrated the first quantum-logic gate. The paper that describes this
important first step is
"Demonstration
of a Fundamental Quantum Logic Gate"
(421 kB PDF).

Quantum Information Program at NIST
In 2000, the director and deputy director of NIST established the NIST Quantum
Information Program. This program is a coordinated effort to build the first
(prototype) quantum logic processor consisting of approximately 10 qubits.
The prototype device will be used to provide a proof-in-principle of the
ability to process quantum information, demonstrate stabilized quantum memory,
and quantum error correction, quantum repeater without output coupling, and to
implement optimal quantum strategies for precision measurement.
The NIST Quantum Information Program is an effort that builds on the broad
internationally recognized research program involving trapped ions by the NIST
Physics Laboratory's Ion Storage Group headed by David Wineland. The expanded
effort includes an additional experimental approach based on neutral atoms
involving the Laser Cooling and Trapping Group headed by William Phillips,
the 1997 Nobel Prize winner in Physics, and the NIST BEC group at JILA led by
Eric Cornell, the 2001 Nobel Prize winner in Physics. The effort also includes
modeling and theory of quantum devices and quantum information by the Quantum
Processes Group led by Paul Julienne and the Electron and Optical Physics
Division led by Charles Clark.
Additional Quantum Information Activities at NIST
|
Superconducting Josephson
junction-based quantum bits for performing quantum measurements, quantum
logic operations, and studying decoherence in solid state material systems,
led by Ray Simmonds. |
|
Study of single
electron transistors (SETs)led by Neil Zimmerman. Charge offset noise is a
key problem that must be overcome for most implementations of quantum
information processing in solid-state systems. |
|
Single-photon
technology and metrology effort led by Alan
Migdall.
Single-photon detectorys, sources, processors, and their metrology is a
critical concern for many quantum information applications. |
NIST also has a multi-laboratory effort underway in support of quantum
communication that is supported in part by the Defense Advanced Research
Projects Agency (DARPA) under its
Quantum
Information Science and Technology (QuIST) program. This effort entitled
A Scalable Quantum Information Network
is led by Carl Williams and includes representatives of the Electronics and
Electrical Engineering Laboratory, the Information Technology Laboratory, and
the Physics Laboratory.
