Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second.
Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future, such traps could be used to realize quantum computers with far more quantum ...
Two physicists at the University of Konstanz are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits "fly."
In work published in Physical Review Letters researchers at Osaka University's Institute of Scientific and Industrial Research (SANKEN) used "the shortcuts to the adiabaticity (STA)" method to greatly speed-up the adiabatic ...
Scientists have created a reprogrammable light-based processor, a world-first, that they say could usher in a new era of quantum computing and communication.
Scientists at Paderborn University have used a new method to determine the characteristics of optical quantum states. For the first time, they are using certain photon detectors—devices that can detect individual light ...
The electron is the basic unit of electricity, as it carries a single negative charge. This is what we're taught in high school physics, and it is overwhelmingly the case in most materials in nature.
Quantum computing engineers at UNSW Sydney have shown they can encode quantum information—the special data in a quantum computer—in four unique ways within a single atom, inside a silicon chip.
Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers ...
In diamonds (and other semiconducting materials), defects are a quantum sensor's best friend. That's because defects, essentially a jostled arrangement of atoms, sometimes contain electrons with an angular momentum, or spin, ...
