Abstract

A scheme is presented for preparing the superposition of coherent states,i.e.,Schr?dinger cat states. These states can be generated by the action of an external impulse functional signal on initial vaccum state of a mesoscopic LC circuit. The nonclassical squeezing properties appear in the circuit under the Schr?dinger cat states.

Preparation of squeezed even coherence state and its nonclassical properties

Ji Ying-Hua, 江西师范大学物理系,南昌 330027

By keeping the frequency of non-dissipative mesoscopic LC circuit a constant and its parameter varying with the step function, the quantum state of the circuit evolves to a squeezed even coherent state from the initial even coherent state. The nonclassical properties, not only squeezing but also antibunching effects, appear in the circuit by adjusting its inductor parameter under the squeezed even coherent state.

Preparation of motional Schrödinger cat states with controllable relative phases

Shi‐Biao Zheng

A scheme is proposed for the generation of motional Schr?dinger cat states with controllable relative phase of an ion trapped in a two-dimensional harmonic potential and driven resonantly by two laser beams propagating along the X and Y directions, respectively. The scheme can also be used to generate other cat states.

Creating multicomponent Schrödinger cat states in a coupled qubit-oscillator system

Pavel Stránský, Pavel Cejnar

We present a method for preparing various exotic modifications of Schr{ö}dinger cat states by coupling a semiclassical oscillator to a system of qubits. Varying the number of qubits and parameters of the protocol (involving quantum quench of the coupled system and a subsequent spin measurement), we bring the oscillator into a coherent superposition composed of an arbitrary number of wavepackets in tunable proportions and motion relations. The method can be implemented with the aid of current experimental techniques and may find applications in quantum information and sensing protocols.

EVOLUTION OF QUANTUM STATE FOR MESOSCOPIC LC CIRCUTI

Wan Hua

The evolution of quantum state with time in the time-dependent mesoscopic LC circuit containing source is studied in this paper.The results indicate that under the action of external source,the system will evolve from the vacuum state to the squeezing state for time-dependent LC circuit containing source,but to the coherent state for time-independent LC circuit.

Teleporting the Schrödinger Cat State

M. H. Y. Moussa, B. Baseia

We present a scheme for the teleportation of a coherent state or a mesoscopic superposition of coherent states — the Schrödinger-cat state. The proposal involves a mesoscopic-correlated state as the quantum channel which is generated through an adaptation of a quantum switch scheme. The required joint measurement performed in a mesoscopic Bell basis is accomplished through a technique for detection of a Schrödinger-cat state "trapped" in a cavity.
