Quantum entanglement without transport: Leaky qubits offer route around noisy channels

The inevitable leakage of energy and information from a quantum system into its surrounding environment is the enemy of quantum technology. Now, researchers have demonstrated that it can be exploited to generate entanglement—the “resource” that quantum technologies use to perform tasks inaccessible to standard classical technologies.

How quantum circuits based on neutral atoms could find and fix errors

Quantum computers, devices that process information by leveraging the laws of quantum mechanics, have been found to outperform classical computers in some advanced tasks. Instead of storing information in the form of classical binary bits (i.e., 0 or 1), quantum computers rely on quantum bits (i.e., qubits), which can also exist in combinations of 0 […]

How physics and mathematical modeling help us make better clothes

A new paper in the journal Nature Physics offers insights into the physics of liquid droplets—and while many people may not appreciate the mathematical accomplishment, they will benefit from the athletic wear and raincoats it makes possible. The recent article, “Tricky Tension,” explores the intersection of physics and textiles and how wetting is influenced by […]

AI unlocks QLED recipe that doubles efficiency and boosts lifetime 40-fold

A technology has been developed that allows artificial intelligence to inversely determine the process conditions for quantum-dot light-emitting diode (QLED) devices—conditions that previously required extensive trial and error to identify.

The Large Hadron Collider is being upgraded so that it can unlock the secrets of the Higgs boson

Deep beneath the French-Swiss border, the world’s largest scientific instrument has fallen silent. After years of smashing protons together at nearly the speed of light, CERN’s Large Hadron Collider (LHC) has stopped operations and entered a long shutdown.

New optical chip design controls light speed in real time, simulations suggest

Seoul National University College of Engineering announced that a joint research team led by Professor Namkyoo Park and Professor Sunkyu Yu of the Department of Electrical and Computer Engineering at SNU, in collaboration with Professor Xianji Piao of the School of Electrical and Computer Engineering at the University of Seoul, has developed a photonic integrated […]

How Gravity from Entropy theory connects the second law of thermodynamics with the emergence of cosmic structure

A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and complex while still obeying the second law of thermodynamics?

A scheme to verify gates of a quantum computer without examining devices

Quantum computers, systems that process information using the principles of quantum mechanics, could solve some problems that cannot be tackled by the classical computers currently used worldwide. Despite their potential, verifying that these computers are working correctly and can reliably perform computations remains challenging.

Single fission experiment maps excess gamma rays from more than a dozen unstable nuclei

In a single experiment, physicists have measured the “excess” emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear fission marks an important step toward a better understanding of one of the key phenomena in modern nuclear physics: the fission […]

Cold radioactive molecules prepped and readied for physics discoveries

For the first time, researchers have developed a way to create chilled molecules containing the radioactive element radium. The resulting laboratory concoctions, generated in part through steps similar to those used to make candy, are poised to help researchers solve one of the biggest mysteries of our universe: How did matter in the early universe […]

Scientists create stable ‘boron graphene’ and uncover quantum liquid crystal state

Graphene has long been regarded as one of the most promising materials for future electronics, but its relatively weak electron interactions have limited its potential for applications such as high-temperature superconductivity. Now, researchers from Tohoku University have overcome a major obstacle by creating a stable version of the long-sought “boron graphene” on the surface of […]

Roadmap paper shows how superconductors can decarbonize transport sector

Superconducting technologies have the potential to supercharge the decarbonization of transport, saving gigatonnes of emissions in the future, a landmark new paper suggests.
