First demonstration of antimatter wave interferometry

Matter waves constitute a crucial feature of quantum mechanics, in which particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated in 1924 by the French physicist Louis ...

Quasiparticles experimentally shown to interfere for first time

Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, ...

Data transfer by controlled noise

In information technology, multiplexing schemes are used to transmit more signals than the number of available transmission channels. Researchers at ETH in Zurich have invented a novel method whereby information is encoded ...

Classic double-slit experiment in a new light

An international research team led by physicists from the University of Cologne has implemented a new variant of the basic double-slit experiment using resonant inelastic X-ray scattering at the European Synchrotron ESRF ...

Physicists measure molecular electronic properties of vitamins

Quantum physics teaches us that unobserved particles may propagate through space like waves. This is philosophically intriguing and of technological relevance: a research team at the University of Vienna has demonstrated ...

Massive particles test standard quantum theory

In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive ...

Experimental method measures robustness of quantum coherence

Researchers at the UAB have come up with a method to measure the strength of the superposition coherence in any given quantum state. The method, published in the journal Proceedings of the Royal Society A, is based on the ...

'Scrambled light' wavemeter breakthrough

A breakthrough innovation in the measurement of lasers can measure changes one millionth of the size of an atom and could revolutionize their use in quantum technologies and healthcare thanks to new, lower-cost technology.
