A team led by Stevens physics professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity — and making that experiment real should be possible with quantum technology, they suggest, in the near future.

Bluefors today announced the immediate availability of a XLDHe High Power System – a cryogen-free, helium-4 powered measurement system that delivers extremely high cooling power for experiments in the 1 K temperature range. The XLDHehp is ideal for demanding applications such as spin qubit quantum computing devices, or single photon detectors for photonic quantum computers.

In their paper, the researchers outline a new strategy for generating spin-squeezed entanglement. They intuited, and together with collaborators in France quickly confirmed via experiment that the ingredients for spin squeezing are present in a ubiquitous type of magnetism found often in nature — ferromagnetism, which is also the force that makes refrigerator magnets stick. They posit that all-to-all interactions are not necessary to achieve spin squeezing, but rather, so long as the spins are connected well enough to sync into a magnetic state, they should also be able to dynamically generate spin squeezing.

A research group led by scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has uncovered details about the formation and behavior of mobile, microscopic, particle-like objects called “excitons” in a class of materials known as van der Waals magnets.

A research team led by Prof PENG Xinhua and Associate Prof. JIANG Min from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters.

Thrasher is working with Japanese tech company Nichia Corporation to build the world’s most accurate compact atomic clock. These clocks, currently about the size of a matchbook, are used in a variety of technologies from backpack radios, GPS receivers, underwater sensors, power grids and satellites. Any drift they experience limits the time these technologies can run on their own without help from a reference clock.

NASA’s Cold Atom Lab, a first-of-its-kind facility aboard the International Space Station, has taken another step toward revolutionizing how quantum science can be used in space. Members of the science team measured subtle vibrations of the space station with one of the lab’s onboard tools — the first time ultra-cold atoms have been employed to detect changes in the surrounding environment in space.

Now, scientists are attempting to make a motion sensor so precise it could minimize the nation's reliance on global positioning satellites. Until recently, such a sensor—a thousand times more sensitive than today's navigation-grade devices—would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology.

Quantum Machines, the leading provider of breakthrough quantum control solutions, today announced the inaugural Adaptive Quantum Circuits (AQC) conference, set to take place September 25-27, 2024, at the Ocean Edge Resort & Golf Club in Brewster, Massachusetts. This first-of-its-kind event will convene the foremost experts from industry, big tech, and top universities to advance the leading edge of hybrid quantum-classical methods.

he Chicago-based Duality quantum accelerator has accepted its fourth cohort of startups into its program as the quantum revolution arrives in Illinois. The five startups in this cohort are developing products and solutions across the quantum technology landscape that includes quantum computing, sensing, and communication, and will look to evolve their technologies and business practices to succeed in various industries like biomedicine and aerospace.
