A sound idea: A step towards quantum computing

A team at the University of Tsukuba studied a novel process for creating coherent lattice waves inside silicon crystals using ultrashort laser pulses. Using theoretical calculations combined with experimental results that ...

Macroscopic electron quantum coherence in a solid-state circuit

A team of researchers at the Centre de Nanosciences et de Nanotechnologies (C2N, CNRS/Univ. Paris-Saclay) has experimentally achieved the coherent propagation of electrons in circuits over macroscopic distances through a ...

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 ...
