Quantum Polaritonics

As light-matter superpositions, polaritons have an intrinsic quantum formulation. This page discusses quantum information processing with—and the nonclassical physics of—polaritons.

Some works take a safe stand and refer to "analogue qubits", which could be useful although essentially classical objects or lacking important quantum features such as entanglement.
