UBC researchers are proposing a solution to a key hurdle in quantum networking: a device that can “translate” microwave to optical signals and vice versa. The technology could serve as a universal translator for quantum computers — enabling them to talk to each other over long distances and converting upContinue Reading
Similar to humans going on journeys of self-discovery, quantum computers are also capable of deepening their understanding of their own foundations. Researchers from Tohoku University and St. Paul’s School, London, have developed a new algorithm that allows quantum computers to analyze and protect quantum entanglement — a fundamental underpinning ofContinue Reading
Scientists based at the AWS Center for Quantum Computing on Caltech’s campus have made a leap forward in figuring out how to suppress errors in quantum computers, a pesky problem that continues to be the greatest hurdle to building the machines of the future. Quantum computers, which are based onContinue Reading
Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advanceContinue Reading
Newly achieved precise control over light emitted from incredibly tiny sources, a few nanometers in size, embedded in two-dimensional (2D) materials could lead to remarkably high-resolution monitors and advances in ultra-fast quantum computing, according to an international team led by researchers at Penn State and Université Paris-Saclay. In a recentContinue Reading
Phase transitions, like water freezing into ice, are a familiar part of our world. But in quantum systems, they can behave even more dramatically, with quantum properties such as Heisenberg uncertainty playing a central role. Furthermore, various spurious effects can cause the systems to lose, or dissipate, energy to theContinue Reading
A team of researchers from Würzburg has for the first time experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. Scientists have long known that electrons can form vortices in quantum materials. What’s new is the proof that these tiny particlesContinue Reading
Once described by Einstein as “spooky action at a distance,” quantum entanglement may now seem less intimidating in light of new research findings. Osaka Metropolitan University physicists have developed new, simpler formulas to quantify quantum entanglement in strongly correlated electron systems and applied them to study several nanoscale materials. TheirContinue Reading
In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions — a feat that many scientists didn’t think was possible. The device, a new type of atom “interferometer,” could oneContinue Reading
A Danish-German research collaboration with participation of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) aims to develop new quantum light sources and technology for scalable quantum networks based on the rare-earth element erbium. The project EQUAL (Erbium-based silicon quantum light sources) is funded by the Innovation Fund Denmark with 40 million Danish crownsContinue Reading
