Single Photon Sources: Quantum Dots vs SPDC

On-demand single photons are the holy grail. Quantum dots have better purity, but SPDC is easier to integrate. Let's compare recent experimental data.

The Future of Photonics: Why light-based qubits might win

Photonics don't require massive dilution fridges and can travel at light speed between processors. Xanadu is making serious progress. What's the catch?

The future of Photonics: Why light-based qubits might win

Unlike superconducting qubits, photons don't need a dilution refrigerator. They can travel through room-temperature fiber optics. The main challenge? Interaction. How do we make two photons talk to each other reliably?
