The fourth annual meeting of the Southwest Quantum Information and Technology Network, or "SQuInT" was held Friday, March 8 through noon Sunday, March 10, 2002 in Boulder, Colorado. This meeting followed the previous meetings held at the University of New Mexico ('99 and '00) and Cal Tech ('01).

Sponsors for the meeting were: NSA/ARDA, DARPA, ONR, Institute for Quantum Information (Cal Tech), LANL, and NIST.

Daytime sessions were held in the auditorium of the main building of the National Institute of Standards and Technology (NIST), 325 Broadway.

Oral presentations began at 9:00 AM, March 8, with a continental breakfast available beforehand.

A poster session was held on Friday, March 9 and a banquet on Saturday night at the Millennium Hotel (the conference hotel).
