How long does a quantum jump take?

Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely — for example the famous ‘photoelectric effect’, first described by Albert Einstein. It was one of the crucial ... Read More »

Skylum introduces AI-powered Quantum HDR Engine to Aurora HDR 2019

Skylum's popular Aurora HDR (High Dynamic Range) photo-editing software has now had its fourth major update. Aurora HDR 2019 features Skylum’s Quantum HDR Engine, an AI-powered tone mapping technology and something Skylum has been working on for the past three years.  When producing an HDR image using multiple bracketed shots, ...

Quantum-level control of an exotic topological quantum magnet

Quantum particles can be difficult to characterize, and almost impossible to control if they strongly interact with each other — until now. An international team of researchers led by Princeton physicist Zahid Hasan has discovered a quantum state of matter that can be “tuned” at will — and it’s 10 ... Read More »

Scientists ‘teleport’ a quantum gate

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand. The findings appear online Sept. 5 in the journal Nature. The key principle behind this new work is quantum teleportation, a ... Read More »

Could a ‘demon’ help create a quantum computer?

Reduced entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms could help speed progress toward creating quantum computers. A team of researchers at Penn State can rearrange a randomly distributed array of atoms into neatly organized blocks, thus performing the function of a “Maxwell’s demon” — a thought experiment from ...

Quantum weirdness in ‘chicken or egg’ paradox

The “chicken or egg” paradox was first proposed by philosophers in Ancient Greece to describe the problem of determining cause-and-effect. Now, a team of physicists from The University of Queensland and the NÉEL Institute has shown that, as far as quantum physics is concerned, the chicken and the egg can ... Read More »

Superradiance: Quantum effect detected in tiny diamonds

The effect has been predicted theoretically decades ago — but it is very hard to provide experimental evidence for it: “Superradiance” is the phenomenon of one atom giving off energy in the form of light and causing a large number of other atoms in its immediate vicinity to emit energy ...
