Amplitude and phase representation of quantum invariants for the time dependent harmonic oscillator
M. Fernandez Guasti, H. Moya-Cessa
The correspondence between classical and quantum invariants is established. The Ermakov Lewis quantum invariant of the time dependent harmonic oscillator is translated from the coo…
Relation between the field quadratures and the characteristic function of a mirror
B. M. Rodriguez, H. Moya-Cessa
We analyze the possibility of measuring the state of a movable mirror by using its interaction with a quantum field. We show that measuring the field quadratures allows to reconstr…
Direct measurement of the Q-function in a lossy cavity
H. Moya-Cessa, R. Juarez-Amaro, I. Ricardez-Vargas
We show that the Q-function corresponding to an electromagnetic field in a lossy cavity can be directly measured by means of a simple scheme, therefore allowing the knowledge of th…
A number-phase Wigner function
Hector Moya-Cessa
One of the most prominent quasiprobability functions in quantum mechanics is the Wigner function that gives the right marginal probability functions if integrated over position or…
