Generation of entangled coherent states of two cavity fields via coupling to a SQUID-based charge qubit

Abstract

We propose a scheme to generate entangled coherent states (ECSs) of two microwave cavity fields coupling to a SQUID-based Cooper pair box (CPB) charge qubit by extending the single-cavity model of coupling between a single microcavity and a CPB charge qubit proposed by Liu et al (2005 Phys. Rev. A 71 063820). We show that by measuring the states of the CPB charge qubit, ECSs of the two cavity fields can be generated with a controllable interaction between the cavities and the CPB charge qubit.

Preparation of Schrodinger cat states of a cavity field via coupling to a SQUID-based charge qubit

Yu-xi Liu, L. F. Wei, Franco Nori

Based on the measurement of charge states, we show that the superpositions of two macroscopically distinguishable coherent states (Schr\\"odinger cat states) of a single-mode cavity field can be generated by a controllable interaction between a cavity field and a SQUID-based charge qubit. After such cat states of the cavity field are created, the interaction can be switched off by the classical magnetic field through the SQUID, and there is no information transfer between the cavity field and the charge qubit. We also discuss the generation of superpositions of two squeezed coherent states.

Multipartite entanglement in the interaction system between a single-mode microwave cavity field and superconducting charge qubits

Shi Zhen-Gang, Xiongwen Chen, Zhu Xi-Xiang +1 more

This paper proposes a method of generating multipartite entanglement through using d.c. superconducting quantum interference devices (SQUID) inside a standing wave cavity. In this scheme, the d.c. SQUID works in the charge region. It is shown that, a large number of important multipartite entangled states can be generated by a controllable interaction between a cavity field and qubits. It is even possible to produce entangled states involving different cavity modes based on the measurement of charge qubits states. After such superpositions states are created, the interaction can be switched off by the classical magnetic field through the SQUID, and there is no information transfer between the cavity field and the charge qubits.

Generation of Multipartite Entangled States Using Switchable Coupling of Cooper-Pair-Boxes

Stefan Rinner, Tindaro Pittorino

We propose a scheme for a switchable coupling between several Cooper-pair boxes in the charge regime. The switch is embodied in a SQUID element contained in the center conductor of a transmission-line resonator. Altering the flux bias through the SQUID allows for changing the effective resonator length. Thus the position of the nodes and anti-nodes of the relevant eigenmodes changes and leads to a variable interaction strength between qubit and cavity vacuum field. For the coupled qubits the interaction is dispersive. An example for the application of this switch is the generation of multipartite entangled states for three and four charge qubits. Although used as a discrete switch in the present proposal, the combined system of SQUID module integrated into the transmission line may be operated continuously as well.

Generation of maximally entangled charge-qubit arrays via a cavity mode

Alexandre Guillaume, Jonathan P. Dowling

We describe an assembly of N Cooper-pair boxes (CPB) contained in a single mode cavity. In the dispersive regime, the correlation between the cavity field and each Cooper-pair box results in an effective interaction between CPBs that can be used to dynamically generate maximally entangled states. With only collective manipulations, we show how to create maximally entangled quantum states and how to use these states to reach the Heisenberg limit in the determination of a spectroscopy frequency. This scheme can be applied to other types of superconducting qubits.

Preparation of macroscopic quantum superposition states of a cavity field via coupling to a superconducting charge qubit

Yu-xi Liu, L. F. Wei, Franco Nori

We propose how to generate macroscopic quantum superposition states using a microwave cavity containing a superconducting charge qubit. Based on the measurement of charge states, we show that the superpositions of two macroscopically distinguishable coherent states of a single-mode cavity field can be generated by a controllable interaction between a cavity field and a charge qubit. After such superpositions of the cavity field are created, the interaction can be switched off by the classical magnetic field, and there is no information transfer between the cavity field and the charge qubit.

Scheme for Generating Cluster States with Charge Qubits in a Cavity

Kehui Song

Based on superconducting charge qubits (SCCQs) coupled to a single-mode microwave cavity, we propose a scheme for generating charge cluster states. For all SCCQs, the controlled gate voltages are all in their degeneracy points, the quantum information is encoded in two logic states of charge basis. The generation of the multi-qubit cluster state can be achieved step by step on a pair of nearest-neighbor qubits. Considering effective long-rang coupling, we provide an efficient way to one-step generating of a highly entangled cluster state, in which the qubit-qubit coupling is mediated by the cavity mode. Our quantum operations are insensitive to the initial state of the cavity mode by removing the influence of the cavity mode via the periodical evolution of the system. Thus, our operation may be against the decoherence from the cavity.
