A tiny light trap could unlock million qubit quantum computers

Stanford physicists have developed a breakthrough optical cavity system that uses tiny microlenses to efficiently capture light from individual atoms, potentially unlocking quantum computers with millions of qubits. The new approach allows information to be read from all quantum bits simultaneously, solving a major scalability problem. Their proof-of-concept demonstrates arrays of 40 and 500+ cavities, with plans to expand to tens of thousands, creating a pathway toward quantum supercomputers that could revolutionize drug discovery, materials design, and code breaking.
