New principle sets maximum limit on quantum information communication
White dwarf star throws light on possible variability of a constant of Nature
An international team led by the University of New South Wales has studied a distant star where gravity is more than 30,000 times greater than on Earth to test its controversial theory that one of the constants ...
Data highway for quantum information
Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently ...
Predicted experimental test will clarify how light interacts with matter at high energies
Collisions of atomic and subatomic particles at very high energies reveal important properties about the beginning of the Universe and the atomic forces, and how fundamental particles are formed and react ...
Quantum communication scheme provides guaranteed security without quantum memories
Scientists capture ultrafast snapshots of light-driven superconductivity
A new study pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.
Physicists build quantum refrigerator based on four quantum dots
Researchers build acoustic tractor beam
Physicists provide experimental proof of theorized Efimov states
Some years ago, Rudolf Grimm's team of quantum physicists in Innsbruck provided experimental proof of Efimov states – a phenomenon that until then had been known only in theory. Now they have also measured ...
The quantum revolution is a step closer
A new way to run a quantum algorithm using much simpler methods than previously thought has been discovered by a team of researchers at the University of Bristol. These findings could dramatically bring ...
Researchers perform first direct measurement of Van der Waals force
Researchers propose method for measuring gravitational impact on antimatter
Swirls in remnants of big bang may hold clues to universe's infancy
South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation.
Solving a physics mystery: Those 'solitons' are really vortex rings
(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying ...
