چکیده
We study the effect of Kerr nonlinearity in quantum thermal machines having a Kerr-nonlinear oscillator as working substance and operating under ideal Otto cycle. first investigate efficiency heat engine show that by varying strength surpasses up to 2.5 times harmonic engine. Moreover, Kerr-nonlinearity makes coefficient performance refrigerator be large 3 refrigerators. These results were obtained using realistic parameters from circuit electrodynamics devices formed superconducting circuits microwave regime.

Complete quantum teleportation with a kerr nonlinearity
We present a scheme for the quantum teleportation of the polarization state of a photon employing a cross-Kerr medium. The experimental feasibility of the scheme is discussed and we show that, using the recently demonstrated ultraslow light propagation in cold atomic media, our proposal can be realized with presently available technology.
متن کاملQuantum control gates with weak cross-Kerr nonlinearity
In this paper, with the weak cross-Kerr nonlinearity, we first present a special experimental scheme called controlled-path gate with which the realization of all possible bipartite positive-operator-value measurements of two-photon polarization states may be nearly deterministic. Following the same technique, the realization of quantum control gates, including the controlled-NOT gate, Fredkin ...

متن کاملThe Quantum Harmonic Otto Cycle
The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element. We compile recent studies of the quantum Otto cycle with a harmonic oscillator as a working medium. This model has the advantage that it is analytically trackable. In addition, an experimental realization has been achieved, employing a...
متن کاملControllable Kerr Nonlinearity via Incoherent Pump Fields in Semiconductor Quantum Wells
A theoretical investigation is carried out into the impact of incoherent pumping fields and quantum interference induced by incoherent pumping fields on the Kerr nonlinearity in a three-level asymmetric semiconductor quantum well system. It is found that Kerr nonlinearity is so sensitive to the rate of incoherent pumping fields, but insensitive to the quantum interference induced by incoherent ...
