Quantum Entanglement of Photons in Doubled q-Fock Space
arXiv:quant-ph/0103024 · doi:10.1142/S0217732301006090
Abstract
A doubled q-Fock space is constructed by introducing an idle mode system dual to the physical one under consideration. The quantum entanglements of photons in the squeezed states and thermal states based on the doubled q-Fock space are discussed.
