Quantum dots can spit out clone-like photons

In the global quest to develop practical computing and communications devices based on the principles of quantum physics, one potentially useful component has proved elusive: a source of individual particles of light with ...

Can ultrashort electron flashes help harvest nuclear energy?

The group led by Fabrizio Carbone at EPFL and international colleagues have used ultrafast transmission electron microscopy to take attosecond energy-momentum resolved snapshots (1 attosecond = 10-18 or quintillionths of ...

Superconducting vortices quantize ordinary metal

Russian researchers, together with their French colleagues, have discovered that a genuine feature of superconductors—quantum Abrikosov vortices of supercurrent—can also exist in an ordinary non-superconducting metal ...

Researchers track the ultrafast emergence of superconductivity

UBC researchers have captured an unprecedented glimpse into the birth of high-temperature superconductivity in cuprates, settling a scientific debate and uncovering new avenues to explore the potential of other unconventional ...

Superconducting qubits can function as quantum engines

(Phys.org)—Physicists have shown that superconducting circuits—circuits that have zero electrical resistance—can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum ...

A quantum computer to tackle fundamental science problems

For more than 50 years, Moore's Law has reigned supreme. The observation that the number of transistors on a computer chip doubles roughly every two years has set the pace for our modern digital revolution—making smartphones, ...
