Macroscopic quantum-state reduction: Uniting Bose-Einstein condensates by interference measurements

Macroscopic Quantum Coherence in Bose–Einstein Condensates

The density of a Bose Einstein condensate (BEC) can undergo a symmetry breaking, either in real space or in momentum space. This occurs in a double well potential, obtained in real space for a BEC of lithium atoms by adding a standing wave light field to the trap potential, or in momentum space for rubidium atoms by Raman coupling two BECs in different magnetic states with two tilted light fiel...

Quantum non-demolition measurements using Bose-Einstein condensates

We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms makes it possible to measure the atom number with minimal back action on the system. This is an example of atomic nonlinear optics that has significant implications in the quantum state preparation of the Bose condensates. Typeset using REVT...
