Stanford Builds Room-Temperature Quantum Device Using Twisted Light, Targeting 10-Plus-Year Path to Phones
2 articles · Updated · ScienceDaily · May 30
Stanford researchers built a nanoscale quantum device that works at room temperature, using twisted light to entangle photons with electron spins instead of relying on near-absolute-zero cooling.
The design pairs molybdenum diselenide with nanopatterned silicon that generates corkscrew-like light, strengthening light-matter coupling and helping preserve the quantum states needed for qubits and communication.
Room-temperature operation could cut the size and cost of quantum hardware, addressing a major barrier that has kept many current systems complex, expensive and difficult to scale.
The team said the approach could support secure communications, sensing, AI and high-performance computing, though broader quantum networks still need better light sources, detectors, modulators and interconnects.
Researchers are testing other material combinations for higher performance, while describing consumer-scale uses such as phone-integrated quantum computing as a 10-plus-year goal.
