We derive the classical compressible Euler equation as the limit of 3D quantum N-particle dynamics as N tends to infinity and Planck's constant tends to zero. We establish strong and quantitative conv...
Heat causes errors in the qubits that are the building blocks of a quantum computer, so quantum systems are typically kept inside refrigerators that keep the temperature just above absolute zero (-459...
In Building 13 on MIT’s campus, there sits a half-a-million-dollar piece of equipment that looks like a long stretched-out chandelier, with a series of gold discs connected by thin silver pipes. The e...

A research team including Brown University faculty and students created a superconducting diode without a magnetic field in multi-layer graphene, a development that could form the basis for future “lo...
Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only...
Electrons and their behavior pose fascinating questions for quantum physicists, and recent innovations in sources, instruments and facilities allow researchers to potentially access even more of the i...
Collaborative research is as fundamental to life at Cornell as hourly chimes, Big Red hockey and Slope Day. It’s a commitment the university takes seriously – and now it’s expanding.
Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions.
Fumbling to find flashlights during blackouts may soon be a distant memory, as quantum computing and artificial intelligence could learn to decipher an electric grid’s problematic quirks and solve sys...
