Abstract

We propose a special conditional phase gate (CPG) U^(π/2) between the photon and the electron spin confined in a quantum dot (QD) embedded in a microcavity operating in the weak-coupling regime. This CPG U^(π/2) provides an optical method to manipulate the QDs with photon parity. By using it, we present a scheme for implementing a state teleportation between two remote QD cavities and a scheme for constructing a photonic Bell-state analyzer. Furthermore, a multipartite Greenberger–Horne–Zeilinger state analyzer is also proposed. This multipartite entanglement analyzer can also be used as a multipartite entanglement generator. All these schemes are operated in the weak-coupling regime, so the high fidelities and efficiencies can be maintained even in the case of a bad cavity, and the schemes are accessible with current technologies.

Proposed scheme to create a CPG U^(π/2) in a weak-coupling cavity. To create this gate, the incident photon needs to travel along the circuit twice. The c-PBS is a polarizing beam splitter in the circular basis. Ti(i=0,1,2,3) are light switches to switch the photon paths. The PS is a π/2 phase shifter, which is applied once only after the photon is transmitted or reflected from the cavity for the first round.
