Quantum machine shows promise for biological research

To date, much has been stated about the promise of quantum computing for myriad of applications but there have been few examples of a quantum advantage for real-world problems of practical interest. This might change with ...

New method enables quantum simulations on larger systems

Through randomly selected measurements, Austrian physicists can now determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum ...

Researchers develop new method to reduce quantum noise

In a recent issue of Physical Review A, Argonne researchers reported a new method for alleviating the effects of "noise" in quantum information systems, a challenge scientists around the globe are working to meet in the race ...

Quantum sensor for photons

A photodetector converts light into an electrical signal, causing the light to be lost. Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light particles non-destructively. ...

Taking statistics to the quantum domain

(Phys.org)—The change point problem is a concept in statistics that pops up in a wide variety of real-world situations, from stock markets to protein folding. The idea is to detect the exact point at which a sudden change ...

Spotting the spin of the Majorana fermion under the microscope

Researchers at Princeton University have detected a unique quantum property of an elusive particle notable for behaving simultaneously like matter and antimatter. The particle, known as the Majorana fermion, is prized by ...

New theory sends temperatures to new lows

Researchers have developed a new theory for recording the lowest temperatures ever measured, with the largest accuracy allowed by the laws of Nature. This line of research holds promise to revolutionise low-temperature physics ...

Quantum computer made of standard semiconductor materials

Physicists at the Technical University of Munich, the Los Alamos National Laboratory and Stanford University (USA) have tracked down semiconductor nanostructure mechanisms that can result in the loss of stored information ...
