While probing how quantum annealers perform when operated faster than desired, a team of scientists at Los Alamos National Laboratory unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and
Physicists at the University of Bonn have shown what the speed limit is for complex quantum operations. The fact that there is a speed limit in the microcosm was already theoretically demonstrated by two Soviet
D-Wave Systems has published a milestone study in collaboration with scientists at Google, demonstrating a computational performance advantage, increasing with both simulation size and problem hardness, to over 3 million times that of corresponding classical
Using the IBM Q computer, physicists at EPFL have verified for the first time the tight relationship between quantum entanglement and wave-particle duality, showing that the former controls the latter in a quantum system. EPFL
An international team led by the University of Nottingham, has demonstrated that only quantum and not classical gravity could be used to create a certain informatic ingredient that is needed for quantum computation. This new
Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a
Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest scale imaginable according to known physics. At this limit, the Planck length, our classical notions of space
Recent work has constructed a relation problem that a noisy constant-depth quantum circuit (QNC0) can solve with near certainty (probability 1−o(1)), but that any bounded fan-in constant-depth classical circuit (NC0) fails with some constant probability. It
For years, physicists have been looking for materials that emulate a Kitaev honeycomb (solid-state model known to birth Majorana fermions in magnetic fields). Physicists from Chung-Ang University, Korea, unveiled the existence of Majorana fermions in α-RuCl3,
To build a universal quantum computer from fragile quantum components, effective implementation of Quantum Error Correction (QEC) is an essential requirement and a central challenge. Since qubits are intrinsically fragile, the most outstanding challenge of
