Quantum nondemolition measurement operator with spontaneous emission
Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We present a theory for quantum nondemolition (QND) measurements of an atomic ensemble in the presence of spontaneous emission. We derive the master equation that governs the evolu…

Photon loss effects on light-mediated non-Gaussian entangled Bose-Einstein condensates projecting with different photon measurement outcomes
Shuai Gao, Manish Chaudhary, Alexey N. Pyrkov +6
The theory of quantum information processing for macroscopic qubits is based on the fact that every macroscopic qubit has a conserved number of particles. However, from an experime…
