Generating squeezed states of the microwave field in a superconducting left-handed transmission line resonator

摘要

A technique relates to a superconducting microwave device. A left-handed resonator include at least one unit cell. A non-linear dispersive medium is connected to the left-handed resonator, such that one end of the left-handed resonator is connected to the non-linear dispersive medium and an opposite end of the left-handed resonator is connected to a port. The left-handed resonator and the non-linear dispersive medium are configured to output a quantum signal in a squeezed state.
