Atomic quantum superposition state generation via optical probing
Anne E. B. Nielsen, Uffe V. Poulsen, Antonio Negretti +1
We analyze the performance of a protocol to prepare an atomic ensemble in a superposition of two macroscopically distinguishable states. The protocol relies on conditional measurem…
Atomic spin squeezing in an optical cavity
Anne E. B. Nielsen, Klaus Molmer
We consider squeezing of one component of the collective spin vector of an atomic ensemble inside an optical cavity. The atoms interact with a cavity mode, and the squeezing is obt…
Stochastic master equation for a probed system in a cavity
Anne E. B. Nielsen, Klaus Molmer
We present a detailed derivation of the stochastic master equation determining the time evolution of the state of a general quantum system, which is placed inside a cavity and subj…
