New principle sets maximum limit on quantum information communication
May the force be with us? Precise measurements test quantum electrodynamics, constrain possible fifth fundamental force
Experiment investigates how classical physics may emerge from quantum physics
Physicists propose measure of macroscopicity; Schrodinger's cat scores a 57
Superheated Bose-Einstein condensate exists above critical temperature
On the origins of the Schrodinger equation
When temperature goes quantum
A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential ...
Correlations of quantum particles help in distinguishing physical processes
Communication security and metrology could be enhanced through a study of the role of quantum correlations in the distinguishability of physical processes, by researchers at the Universities of Strathclyde ...
Researchers describe the wavefunction of Schroedinger's cat
Schrödinger's cat highlights a long-standing dilemma in quantum mechanics: is the cat really alive and dead, or is the weirdness just in our head?
Scientists tame Schrodinger's cat for a new type of quantum computer
Physicists at the University of Sussex have tamed one of the most counterintuitive phenomena of modern science in their quest to develop a new generation of machines capable of revolutionizing the way we ...
Fraud-proof credit cards possible with quantum physics
Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Researchers find qubits based on trapped ions offer a promising scalable platform for quantum computing
Cooling with the coldest matter in the world
Physicists at the University of Basel have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree ...
