Entangled Nonorthogonal States and Their Decoherence Properties
Osamu Hirota, Steven J. van Enk, Kazuo Nakamura, Masaki Sohma, Kentaro Kato
abstract: This paper presents properties of the so-called quasi-Bell states: entangled
states written as superpositions of nonorthogonal states. It is shown that a
special class of those states, namely entangled coherent states, are more
robust against decoherence due to photon absorption than the standard bi-photon
Bell states.
