Exciton-Polaritons: Half Light, Half Matter
When an exciton couples strongly to a photon in a cavity, the two lose their separate identities — forming a polariton that is part light, part matter.

Polariton Condensates and Quantum Simulators
Exciton-polaritons can condense into a single macroscopic quantum state and be patterned into lattices. That makes them a natural platform for simulating quantum many-body physics — not for running Shor's algorithm.

All-Optical Switching: The Nonlinearity Problem and How Polaritons Solve It
Photons barely interact, which makes them fast but hard to switch. Polaritons borrow interaction from excitons — and that trade may be the key to optical logic.
