Photonic Quantum Computing
A quantum computing approach that uses photons as qubit carriers. It features room-temperature operation and strong environmental adaptability; its principal techniques include Gaussian boson sampling.
Timeline (last 90 days)
The quantum computing routes that can simultaneously satisfy the three conditions of "manufacturable, scalable, and demonstrated quantum advantage" in public experiments are mainly concentrated in the two routes of photonic quantum and superconducting.
Photonic quantum computing uses photons as qubit carriers and can operate at room temperature, with representative companies including PsiQuantum and Xanadu.
It is extremely technically challenging for photons to interact directly with each other to achieve deterministic two-qubit gate operations, and photon loss affects large-scale computing performance.
