Qubits based on Polariton Rabi Oscillators
arXiv:1401.3509 · doi:10.1103/PhysRevLett.112.196403
Abstract
We propose a novel physical mechanism for creation of long lived macroscopic exciton-photon qubits in semiconductor microcavities with embedded quantum wells in the strong couping regime. We argue that the coherence time of Rabi oscillations can be dramatically enhanced due to their stimulated pumping from a permanent thermal reservoir of polaritons. The polariton qubit is a superposition of lower branch (LP) and upper branch (UP) exciton-polariton states. We discuss applications of such qubits for quantum information processing, cloning and storage purposes.
