A group of physicists in Utrecht, San Sebastián and Pennsylvania have created a new artificial molecule that is insulating inside but has electronic states localized in its corners. These states have zero energy, and for ...
It may still be decades before quantum computers are ready to solve problems that today's classical computers aren't fast or efficient enough to solve, but the emerging "probabilistic computer" could bridge the gap between ...
Physicists studying the strange behavior of metal alloys called heavy fermions have made a surprising discovery that could be useful in safeguarding the information stored in quantum bits, or qubits, the basic units of encoded ...
Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these ...
A UNSW study published this week resolves key challenges in creation of hole-based artificial atoms, with excellent potential for more-stable, faster, more scalable quantum computing.
Physicists have experimentally demonstrated 18-qubit entanglement, which is the largest entangled state achieved so far with individual control of each qubit. As each qubit has two possible values, the 18 qubits can generate ...
Searching large, unordered databases for a desired item is a time-consuming task for classical computers, but quantum computers are expected to perform these searches much more quickly. Previous research has shown that Grover's ...
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) ...
Physicists from the Moscow Institute of Physics and Technology (MIPT) and Royal Holloway, University of London, have demonstrated an effect known as quantum wave mixing on an artificial atom. Their results, published in the ...
(Phys.org)—Physicists have shown that superconducting circuits—circuits that have zero electrical resistance—can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum ...
