CNOT and Bell-state analysis in the weak-coupling cavity QED regime
Physical review letters, 2010•APS
We propose an interface between the spin of a photon and the spin of an electron confined
in a quantum dot embedded in a microcavity operating in the weak-coupling regime. This
interface, based on spin selective photon reflection from the cavity, can be used to construct
a cnot gate, a multiphoton entangler and a photonic Bell-state analyzer. Finally, we analyze
experimental feasibility, concluding that the schemes can be implemented with current
technology.
