Cooperative radiation phenomena for Quantum information processing and metrology
Abstract
Most cutting edge applications in quantum information science and quantum metrology involve control over many body quantum systems coupled to optical or microwave radiation fields. In such systems, the spontaneous emission into the vacuum modes of the environment and the subsequent loss of information into these undesired channels sets a fundamental performance limit for quantum devices. Such spontaneous emission is typically assumed to be an independent process for each emitter. This is, however, not always the case: in many practical systems, dissipation must be correlated to account for the interference between light originating from different emitters. For systems such as trapped atoms or solid state excitons, where dissipation predominantly stems from radiative decay, this can result in complex many body sources of decoherence. At the same time, this effect could create entire manifolds of protected subradiant states whose decay rates approach zero with increasing system size.
