Researchers at Stanford University have developed a new device that uses twisted light to make quantum computers work without extreme cooling. This breakthrough could lead to smaller and more affordable quantum technologies.

Quantum computers are notoriously difficult and expensive to operate. Most require temperatures near absolute zero, about -459 degrees Fahrenheit, to maintain the fragile quantum states needed for computation and communication. Now, researchers at Stanford University have developed a nanoscale optical device that functions at room temperature while linking the quantum properties of light and electrons. This advance could help pave the way for smaller, lower-cost quantum technologies capable of transmitting information across long distances.

The new device enables entanglement between photons, the particles that make up light, and electrons. This quantum connection is considered a fundamental requirement for future quantum communication systems. The team used a thin patterned layer of molybdenum diselenide (MoSe2) with a nanopatterned silicon substrate to create this device.

The researchers say the compact design is also relatively inexpensive and practical compared with many current quantum systems. If further developed, the technology could contribute to advances in secure communications, advanced sensing, high-performance computing, artificial intelligence, and other emerging applications.
