Quantum Brakes in Molecules

Physicists of the Laboratory for Attosecond Physics have measured the flight times of electrons in molecules after their creation with light. The small quantum particles were emitted from a specific atom within the molecules, which […]

SiC can boast some of the quantum merits of diamond

Researchers at the University of Science and Technology in Hefei and Wuhan University in China have demonstrated SiC can boast some of the quantum merits of diamond (nitrogen-vacancy (NV) centers) with the additional advantage of […]

Dynamics of spin thermalization

A group of researchers based at The City College of New York (CCNY) provide new insights on the dynamics of spin thermalization at the nanoscale. Understanding why this happens and how it can be controlled is presently at […]

Superconductivity to the Edge

A discovery that long eluded physicists has been detected in a laboratory at Princeton. A team of physicists detected superconducting currents — the flow of electrons without wasting energy — along the exterior edge of […]

Long-lived pionic helium

MPQ Scientists opened a new window into the quantum world. After eight years they succeeded in a challenging experiment with PSI and CERN: they created an artificial atom, the so-called pionic helium, in which the […]

Scientists force electrons to break Ohm’s Law

Scientists in the Quantum Dynamics Unit at Okinawa Institute of Science and Technology Graduate University (OIST) are running experiments to see how the motion of electrons is impacted by fluid. Ohm’s law, a physics law, […]

An optical version of Quantum Hall Effect (QHE)

At Rensselaer Polytechnic Institute, researchers working at the intersection of materials science, chemical engineering, and physics are uncovering an optical version of Quantum Hall Effect (QHE). QHE is a difference in mechanical voltage that is […]

Building block for quantum computers

Researchers at Johns Hopkins built on their previous study about the search for basic building blocks of materials called superconductors with spin-triplet pairing, which were considered to be very rare. The rare property of spin-triplet […]

The diamond quantum  revolution

In the April 2020 issue of Physics World, editors explain how diamond, this special form of carbon, now has many practical quantum applications.

Towards a nanomechanical quantum switchboard

Physicists at Universität Regensburg have coupled the vibrations of a macromolecule, a carbon nanotube, to a microwave cavity, creating a novel and highly miniaturized optomechanical system. The team achieved this by using the quantization of […]

New two-dimensional design of a quantum computer

Scientists from Tokyo University of Science, RIKEN Centre for Emergent Matter Science, Japan, and University of Technology, Sydney, have collaborated and proposed a novel two-dimensional design that can be constructed using existing integrated circuit technology. […]

Alternative route to topological superconductivity

Researchers at the University of Copenhagen, in collaboration with Microsoft Quantum researchers, have used a pencil-shaped semiconductor measuring only a few hundred nanometers in diameter to uncover a new route to topological superconductivity and Majorana […]

Optically-controlled quantum computation

Scientists at Ames Laboratory, Brookhaven National Laboratory, and the University of Alabama Birmingham have discovered a light-induced switching mechanism in a Dirac semimetal. The mechanism establishes a new way to control the topological material, driven […]

Quantum entanglement offers unprecedented precision for GPS

University of Arizona engineering and optical sciences researchers, in collaboration with engineers from General Dynamics Mission Systems, demonstrate how a combination of two techniques (radio frequency photonics sensing and quantum metrology) can give sensor networks […]

New cooling technique to nanokelvin temperatures

MIT physicists have found a way to cool molecules of sodium lithium down to 220 nanokelvins, just a hair above absolute zero. They did so by applying a technique called collisional cooling, in which they immersed molecules […]

Scientists explore underwater quantum links for submarines

Underwater quantum links are possible across 30 meters (100 feet) of turbulent water, scientists have shown. Such findings could help to one day secure quantum communications for submarines. Researchers have investigated establishing quantum communications links through […]
