SQuInT brings together researchers in theoretical and experimental quantum information science from around the Southwest and beyond.

The 10th Annual SQuInT Workshop was hosted by the University of New Mexico Center for Advanced Studies, and organized by Ivan Deutsch and JM Geremia with assistance from Jennie Peer and Cathy Webster.

Invited Speakers:

  • Eddie Farhi (MIT)
  • Serge Haroche (Ecole Normale Superieure)
  • Patrick Hayden (McGill University)
  • Alex Kuzmich (Georgia Tech)
  • Giacomo Mauro D'Ariano (University of Pavia)
  • Irina Novikova (College of William & Mary)
  • Ray Simmonds (NIST Boulder)

Tutorials and Pedagogical Lectures:

To help celebrate our 10th Anniversary, we held a day of tutorials and pedagogical lectures on Thursday February 14, the day preceding the main meeting February 15-17. These lectures mixed introductory material for newcomers to Quantum Information Science with some of the details of the latest techniques in theory and experiment, of interest across a wide range of subdisciplines.
  • Steven van Enk (University of Oregon)
    "Entanglement and Verification"
  • John Martinis (University of Californian, Santa Barbara)
    " Measuring Coherence Times"
  • Howard Barnum (Los Alamos National Laboratory) and
    Andrew Landahl (University of New Mexico)
    "Convexity and Positivity in Quantum Information"
