Split-ring polariton condensates as macroscopic two-level quantum systems
Split-ring polariton condensates as macroscopic two-level quantum systems
Superposition states of circular currents of exciton-polaritons mimic the superconducting flux qubits. The phase of a polariton fluid must change by an integer number of 2π when going around the ring. If one introduces a π-phase delay line in the ring, the fluid is obliged to propagate a clockwise or …
