About Photonic Technology
Photonic quantum computers encode quantum information in photons — particles of light — using properties such as polarization, path, time-bin, or continuous-variable quadratures. Gaussian boson sampling (GBS) machines like Xanadu Borealis manipulate squeezed states of light through linear optical networks of beam splitters and phase shifters. Measurement-based approaches are common.
Operates at room temperature (no cryogenics required), photons travel at the speed of light with minimal decoherence, and photonic hardware is compatible with existing fiber-optic telecommunications infrastructure for quantum networking.
Deterministic photon-photon interactions are extremely difficult to engineer, making universal fault-tolerant quantum computation challenging. High photon loss rates and detector inefficiencies limit circuit depth. Current GBS machines are specialized rather than general-purpose.
Variable; loss-dominated; ~98% for single-photon detectors
Picoseconds for passive operations; detector timing ~ns
