Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can’t be copied or split and thus are secure—in the network of optical fibers we already have. This […]

In thermodynamics, an “adiabatic process” is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the […]
Quantum bits (qubits) are the fundamental building blocks of quantum information processing. A novel qubit platform invented at the U.S. Department of Energy’s (DOE) Argonne National Laboratory exhibits noise levels thousands of times lower than […]
With a carefully designed experiment and a handful of tin atoms, University of Tennessee, Knoxville’s physicists have found a long-sought form of superconductivity, taking one more step toward creating custom quantum materials. Click to rate […]
A new study by University of Maryland chemical physicists demonstrates how to control the nuclear spin of molecular hydrogen (H2) by simply freezing it in dry ice. This new technique, published in the journal Physical […]
Theoretical physicists in the US have discovered a “speed limit” on the time taken for quantum information to spread through larger systems. Publishing their results in Physical Review Letters, Amit Vikram and colleagues at the […]
Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a breakthrough that could transform medical […]
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications in communications and […]
A rainbow reveals with colors what otherwise remains hidden: light is “refracted” by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, like LCD screens and broadband connections based […]
Three RIKEN researchers have demonstrated a way to stop problematic “dark modes” from squelching intriguing effects in quantum systems. This advance could help with the development of more versatile quantum devices that can be used […]
