Tutorial #7

Quantum Noise, Quantum Limited Measurements, and Conditional Quantum Evolution

Pre-registration only — no on-site registration for tutorials

Sunday, March 9
1:30 p.m. - 5:30 p.m.
La Galerie 2
New Orleans Marriott Hotel
555 Canal Street

Who Should Attend
Graduate students, post‑docs, principal investigators, and funding agents interested in gaining a working knowledge of continuous quantum measurement theory and conditional dynamics, with special emphasis on solid‑state applications.

Tutorial Description
The modern theory of the evolution of our state of knowledge about a quantum system subject to a continuous weak measurement has been highly developed in the quantum optics community in the last three decades, but is largely unknown in the condensed matter community. Several experimental developments make this a timely topic. First, rapid progress is being made towards ground‑state cooling and quantum‑limited measurements of the position of nano‑mechanical oscillators. Second, there is the recent advent of highly coherent solid‑state qubits and many new measurement schemes to read out these qubits. It would be very useful to bring these developments from quantum optics to the attention of the condensed matter community.
