摘要:
In this survey, we present single-photon states of electromagnetic fields, discuss discrete measurements of a single-photon field, show how a linear quantum system responds to a single-photon input, investigate how a coherent feedback network can be used to manipulate the temporal pulse shape of a single-photon state, present single-photon filter and master equations, and finally discuss the generation of Schr?dinger cat states by means of photon addition and subtraction.
关键词:  Quantum control · Continuous-mode single photon states · Coherent feedback · Filtering · Master equations · Schrödinger cat states
