(Phys.org)—Theoretically, the laws of quantum mechanics – particularly the "no-cloning theorem" – guarantee that any attempt at counterfeiting a credit card, bill, coin, token, etc., will fail if the object is embedded ...
Research drawing on the quantum "anti-butterfly effect" solves a longstanding experimental problem in physics and establishes a method for benchmarking the performance of quantum computers.

(Phys.org) —A team of physicists in Israel has used the scattering of a photon when it strikes an atom to better understand the process of decoherence. In a paper the team has published in the journal Science, the group ...
(Phys.org)—Dissipation and decoherence are typically considered harmful to solar cell efficiency, but in a new paper scientists have shown that these effects paradoxically make the exciton lifetime in semiconducting carbon ...
When American physicist Richard Feynman in 1982 proposed creating a quantum computer that could solve complex problems, the idea was merely a theory scientists believed was far off in the future.

(PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they ...
A theoretical breakthrough in understanding quantum chaos could open new paths into researching quantum information and quantum computing, many-body physics, black holes, and the still-elusive quantum to classical transition.

In quantum physics, some of the most interesting effects are the result of interferences. Decoherence, or loss of coherence, occurs when a quantum system eventually loses the ability to produce interferences, due to external ...
Quantum computers promise to perform certain types of operations much more quickly than conventional digital computers. But many challenges must be addressed before these ultra-fast machines become available, among them, ...
