An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infineon, together with institutes of the Fraunhofer-Gesellschaft (IAF, IPMS) as well as the Leibniz Association (IHP, IKZ), the universities of Regensburg and Konstanz and the quantum […]
A quantum algorithm for string matching
Algorithms that search for a pattern within a larger data-set appear ubiquitously in text and image processing. Pattern matching algorithms are used ubiquitously used in image processing, the study of DNA sequences, and data compression […]
Experimental quantum homomorphic encryption
Quantum computers promise not only to outperform classical machines for certain important tasks, but also to preserve privacy of computation. For example, the blind quantum computing protocol enables secure delegated quantum computation, where a client […]
Ion-optics-based quantum microscope can image individual atoms
A team of researchers at Universität Stuttgart, Germany, has developed an ion-optics-based quantum microscope that is capable of creating images of individual atoms. The microscope built by the team began with the use of an […]
Lack of symmetry in qubits might explain matter/antimatter
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 […]
A speed limit also applies in the quantum world
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 […]
Resource-efficient quantum algorithm for protein folding
A team of researchers at IBM Research – Zurich, Switzerland, has presented a resource-efficient quantum algorithm for protein folding. Predicting the three-dimensional structure of a protein from its primary sequence of amino acids is known […]
CERN’s ATLAS: Evidence of a rare Higgs boson decay
CERN’s ATLAS has found first evidence of the Higgs Boson decaying to two leptons (either an electron or a muon pair with opposite charge) and a photon. Known as “Dalitz decay”, this is one of the rarest […]
Performance advantage in quantum simulation
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 […]
IBM’s Quantum computer links two quantum revolutions
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 […]
