内容摘要：Polariton lasers are semiconductor light-emitting devices based on the bosonic condensation of half-light-half-matter quasiparticles: exciton-polaritons. Due tot he stimulated scattering to one or several quantum states, exciton-polaritons form bosonic condensates characterized by high spatial coherence and super fluid properties, Exciting coherent superpositions of pairs of eigen states of polariton superfluids in elliptical traps we create qubits characterized by very slow decoherence dynamics, Quantum logic operations can be performed on these superfluid polariton qubits with use of control laser pulses. We demonstrate the Hadamard and Pauli operations on a single qubit, the entanglement of two qubit sand double-qubit gate operations, The new platform for quantum computing provided by polariton lasers is highly promising due to the remarkable scalability of polariton quantum networks and their potential for room temperature operation.
