1202.4718 (A. M. Zagoskin et al.)

Heat cost of parametric generation of microwave squeezed states    [PDF]

A. M. Zagoskin, E. Il'ichev, Franco Nori
In parametric systems, squeezed states of radiation can be generated via
extra work done by external sources. This eventually increases the entropy of
the system despite the fact that squeezing is reversible. We investigate the
entropy increase due to squeezing and show that it is quadratic in the
squeezing rate and may become important in the repeated operation of tunable
oscillators (quantum buses) used to connect qubits in various proposed schemes
for quantum computing.
