Stanford Researchers Build Room-Temperature Quantum Device Using Twisted Light

3 articles · Updated · ScienceDaily · Jun 11

Stanford researchers developed a nanoscale optical device that entangles photons with electrons at room temperature, removing the near-absolute-zero cooling many quantum systems now require.
The device pairs a thin molybdenum diselenide layer with nanopatterned silicon that generates corkscrew-like “twisted light,” transferring spin to electrons and stabilizing the quantum state needed for qubits.
That room-temperature operation could cut the size and cost of quantum hardware while supporting long-distance quantum communication, secure networks, sensing, AI and high-performance computing applications.
The team, whose results appeared in Nature Communications, is testing other material combinations and says integrating such components into broader quantum networks remains a 10-plus-year goal.

Room-Temperature Quantum Entanglement at Stanford: Paving the Way for Scalable Quantum Communication and Devices

Overview

Stanford University has developed a nanoscale optical device that can entangle photons and electrons at room temperature, overcoming the traditional need for extreme cooling to maintain fragile quantum states. This breakthrough allows quantum operations without bulky, costly cryogenic systems, making it possible to maintain quantum states under normal conditions. As a result, quantum hardware can become smaller, more affordable, and practical for widespread use. The device’s innovative design, using a patterned layer of molybdenum diselenide on a nanopatterned silicon substrate, marks a major step toward practical quantum communication and technology.
