In a new study, researchers demonstrate an improvement of more than two orders of magnitude in the spin coherence time of nitrogen-vacancy centers as compared with previous measurements. The findings could advance quantum sensing, enable squeezing and many-body entanglement, and open a path to simulating driven, interaction-dominated quantum many-body Hamiltonians. From brain to heart to [...]

Using metamaterial surfaces, researchers were able to amplify the signal of the photonic Spin Hall Effect, making it directly observable with simple detection techniques, and control the propagation of light and circular polarization. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of [...]

In a newly published study, physicists at UC Santa Barbara used a switch to manipulate light on superconducting chips, providing a new understanding in the quantum realm. Santa Barbara, California –– Physicists at UC Santa Barbara are manipulating light on superconducting chips, and forging new pathways to building the quantum devices of the future –– [...]

Using an artificial atomic nuclei fabricated on graphene, a team of researchers imaged the “atomic collapse” states theorized to occur around super-large atomic nuclei. The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with microscopic artificial atomic [...]

A newly published study looks at recent advances in quantum measurements, coherent control, and the generation of entangled states, while describing some of the challenges that remain ahead for quantum computing and other applications. New tech­nolo­gies that exploit quan­tum behav­ior for com­put­ing and other appli­ca­tions are closer than ever to being real­ized due to recent [...]

A newly published study from scientists at the University of York dismisses the so-called firewall paradox and reveals new insights into the life and death of black holes. Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions about large black holes contradicted Einstein’s [...]

MIT scientists have developed a new process for creating quantum dots with four important qualities, high particle uniformity, high photoluminescence quantum yields, narrow and symmetric emission spectral lineshapes and minimal single-dot emission intermittency, which should result in improved quantum-dot performance. Quantum dots — tiny particles that emit light in a dazzling array of glowing colors [...]

Physicists have been able to create an atomic gas that can attain a temperature below absolute zero, -273.15˚C. They were able to create this gas using negative-Kelvin materials and new quantum devices. The scientists published their findings in the journal Science¹. The absolute temperature scale dates back to Lord Kelvin, who created it in the [...]

Quantum computers will be able to perform tasks that silicon-based computers wouldn’t be able to do, like cracking the codes that protect bank transactions. Several research teams have revealed solid evidence that quantum physics does embody a level of complexity that classical computers could never match. The new devices these groups have built are much [...]

Scientists discovered a magnetic field that can control the flow of heat from one body to another. It was first predicted 50 years ago, and its effect could someday lead to a new generation of electronic devices that use heat rather than charge to carry information. The scientists published their findings in the journal Nature. [...]

Samarium hexoboride, a compound that had been poorly understood and that can gain conducting properties at very low temperatures, may be a topological insulator in its bulk form, conducting electricity on its surface while the rest of the material behaves like an insulator. The scientists published their findings in three papers in preprints on arXiv [...]

Three years ago, Jian-Wei Pan and his colleagues were able to quantum teleport information across 16 kilometers. This was one of the first major steps to the research team’s ultimate goal of teleporting photons to a satellite orbiting the Earth. Once this is achieved, it will establish the first links of the quantum Internet, which [...]
