Current obstacles

Photon detection efficiencyReducing photon loss in the optical path and improving detector sensitivity are critical for scaling qubit counts.

Physics limits

Photon sources are limitedCurrent photon sources cannot generate on-demand quantum light efficiently; single-photon sources operate at low rates, limiting system throughput.
Optical components are lossyEvery optical element (beamsplitter, fiber, detector) loses some photons; cumulative losses in large systems reduce fidelity.

How it works

2 parts

Photons

Light-based qubits

Uses photons as quantum information carriers, avoiding the extreme cooling of superconducting systems.

Room Temperature

No cryogenic infrastructure

Systems operate at room temperature, eliminating the cost and complexity of dilution refrigerators required by other approaches.
