Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly...
For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this ex...

Time crystals. Microwaves. Diamonds. What do these three disparate things have in common?
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus in the field, especially in the race for super-fast quantum computers.
Ateam of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operati...

In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a partic...
Scientists have taken a quantum leap forward towards future computing after discovering that ‘background interference’ in quantum-level measurements, may be the very thing they need to unlock the pote...

Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the University of Wisconsin-Madison created an atomic circuit that may he...
Mesoscopic d-Wave Qubits: Can High-Tc Cuprates Play a Role in Quantum Computing?
high-Tc Josephson T-breaking d-wave qubit decoherence design scalability
2010/4/12
Due to nontrivial orbital pairing symmetry, surfaces and interfaces of high-Tc superconductors support states which violate time-reversal (T-) symmetry. Such naturally degenerate states, useful as wor...
Quantum Computing with Electrons on Liquid Helium
Quantum computing Decoherence Electrons on helium
2010/4/12
A quantum computer based on electrons floating over liquid helium is described. Each qubit is made of combinations of ground and first excited states of an electron trapped over micro-electrodes just ...
