Phase operators of the harmonic oscillator and suppression of a number state.
The phase properties of the quantized electromagnetic field have been studied using operators P± of the harmonic oscillator whose classical analogs are exp(i) being the classical phase. P+ and P- are used to construct a unitary operator Up()=exp(P+-±*P-) and the properties of the state generated by...

| description | The phase properties of the quantized electromagnetic field have been studied using operators P± of the harmonic oscillator whose classical analogs are exp(i) being the classical phase. P+ and P- are used to construct a unitary operator Up()=exp(P+-±*P-) and the properties of the state generated by Up from a number state are studied. It is shown that by tuning it is possible to produce a pure state 0=Up(±)0 in which a specific number-state component is suppressed. © 1989 The American Physical Society. |
