Scientists have created a new theory on how to create transistors for quantum computers using photons. The transistors can process optical signals and enable the development of supercomputers that can solve extremely complicated tasks.
Scientists have found experimental evidence of quantum chaos in a system with freely dispersing components. The researchers replicated an historical experiment, demonstrating photoelectric effect and observing Ericson fluctuations.
The National Science Foundation (NSF) supports six Nobel laureates in chemistry, physics, and economics with its grants. NSF supported Robert H. Grubbs, Richard R. Schrock, Yves Chauvin, John L. Hall, Theodor W. Hänsch, and Roy J. Glauber for their pioneering work on metathesis, laser-based precision spectroscopy, and game-theory analy...
Researchers at Yale University have developed a miniaturized superconducting cavity that enables quantum optics experiments on a microchip. The system allows for rapid exchange of energy between photons and atoms, demonstrating the potential for faster computing with quantum qubits.
The university's new Laboratory for Quantum Control will enable original experiments at an internationally competitive level, focusing on controlling atoms and molecules using ultrashort light pulses. The lab aims to lead to increased computer capability, improved optical-fiber communications, and new forms of electronics.
The NIST quantum key distribution system generates a verifiably secret key at a rate of 1 million bits per second, about 100 times faster than previously reported systems. The system uses time-stamping and high-speed observations to identify photons from the sender among multiple photons from other sources.
Scientists have successfully created a crystal of atoms and observed a quantum phase transition, shedding light on fundamental problems in solid-state physics, quantum optics, and atomic physics. By increasing the strength of a microscopic lattice, researchers induced a transition from a superfluid phase to an insulating Mott phase.
