Quantum photonics roadmap — how Xanadu and PsiQuantum are looking to transfer qubits through beams of light

Quantum photonics is presented as a promising hardware path that uses single photons to encode qubits.

The article compares Xanadu’s continuous-variable approach with PsiQuantum’s dual-rail encoding strategy.

Both companies are aiming for large-scale, error-corrected quantum computers, with funding and listing plans seen as key commercialization signals.

Photonic systems are drawing attention for their scalability and manufacturability, making them a major candidate in the quantum computing roadmap.
