The road to a quantum future may be longer and more winding than some expect, but the potential it holds is profound, writes UTS Associate Professor Chris Ferrie.
The term molybdenum disulfide may sound familiar to some car drivers and mechanics. No wonder: the substance, discovered by U.S. chemist Alfred Sonntag in the 1940s, is still used today as a high-performance lubricant in ...
Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ellipticity) detection ...
A team of researchers from the Institute of Optics of CSIC and the Institute of Photonic Sciences (ICFO) of Barcelona has proposed a new design to implement highly directional single-photon sources, which constitutes an improvement ...
Vortices of light, null regions of intensity surrounded by spiral phases, make up the skeleton of a wavefield and influence the properties of light. Since the discovery of the tight connection of optical vortices and orbital ...
Quantum computers promise to solve challenging tasks in material science and cryptography that will remain out of reach even for the most powerful conventional supercomputers in the future. Yet, this will likely require millions ...
The development of quantum computing means that the use of classic cryptography for secure communications is in danger of becoming obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to ensure ...
A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of "local causality" formulated by Albert Einstein in response ...
Large numbers can only be factorized with a great deal of computational effort. Physicists at the University of Innsbruck, Austria, led by Wolfgang Lechner are now providing a blueprint for a new type of quantum computer ...
For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material. In this case, it would not follow the laws of classical physics even on a macroscopic level, but rather ...
