New technique uses fraction of measurements to efficiently find quantum wave functions
The result of every possible measurement on a quantum system is coded in its wave function, which until recently could be found only by taking many different measurements of a system and estimating a wave function that best ...
Rice physicist emerges as leader in quantum materials research
"Emergent" is a key concept in the work of Rice University theoretical physicist Andriy Nevidomskyy, and thanks to two prestigious new awards, it is also an apt description of his work.
Electrons moving in a magnetic field exhibit strange quantum behavior
The dynamic behavior of electrons in magnetic fields is crucial for understanding physical processes, such as the quantum Hall effect, which are important in many areas of solid state physics, including electrical ...
Physicists introduce another quantum animal: The Quantum Pigeon
Recently physicists at Chapman University's Institute for Quantum Studies introduced the Quantum Cheshire Cat. Now they have introduced another quantum animal: the Quantum Pigeon.
Quantum leap in lasers brightens future for quantum computing
Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, ...
Boosting the force of empty space
Vacuum fluctuations may be among the most counter-intuitive phenomena of quantum physics. Theorists from the Weizmann Institute (Rehovot, Israel) and the Vienna University of Technology propose a way to amplify ...
There's a kind of Hush surrounding quantum systems

Physicists Use Computer Models to Reveal Quantum Effects in Biological Oxygen Transport
(Phys.org) —Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well characterised protein found in muscle to develop a new picture ...
Highway for ultracold atoms in light crystals
When a superconductor is exposed to a magnetic field, a current on its surface appears which creates a counter field that cancels the magnetic field inside the superconductor. This phenomenon, known as "Meissner-Ochsenfeld ...
Effort to model Facebook yields key to famous math problem (and a prize)
(Phys.org) —Dan Spielman, a Yale computer scientist, wasn't looking for a new problem. He was already deeply immersed in a tricky effort to model complex online communities like Facebook, hoping to gain ...
