We propose a scheme for implementing the Grover search algorithm
with two superconducting quantum interference devices (SQUIDs) in a
cavity. Our scheme only requires single resonant interaction of the
SQUID-cavity system and the required interaction time is very short.
The simplicity of the process and the reduction of the interaction
time are important for restraining decoherence. 相似文献

This paper proposes a scheme for entanglement concentration of unknown triparticle W class states with a certain probability. This protocol is mainly based on the coincidences of single-photon detectors and requires single-photon detectors and linear optical elements. The scheme is feasible within current technology. 相似文献

Entanglement Purification for Mixed Entangled Quantum Dot States via Superconducing Transmission Line Resonators 下载免费PDF全文
An entanglement purification protocol for mixed entangled states is presented via double quantum dot molecules inside a superconducing transmission line resonator (TLR). In the current scenario, coupling for arbitrary double quantum dot molecules can be tuned via the TLR in the large detuning region by controlling the qubit level splitting. The TLR is always empty and only virtually excited, so the interaction is insensitive to both the TLR decay and thermal field. Discussion about the feasibility of our scheme shows that the entanglement purification can be implemented with high fidelity and successful probability. 相似文献

Generation of Multipartite Ionic Entangled States only by Single-Qubit Measurements via Linear Optical Elements 下载免费PDF全文
We propose a scheme for generation of multipartite ionic Greenberger-Horne-Zeilinger (GHZ) states only by single-qubit measurements. Our scheme not only does not need joint measurements but also avoids the difficulty of synchronizing the arrival time of the two scattered photons, which is faced by the previous schemes. Therefore our entanglement generation scheme can be implemented more easily than the schemes based on atomic interference in experiment. 相似文献
