Keeping it together: Protecting entanglement from decoherence and sudden death
(PhysOrg.com) -- Decoherence can be metaphorically seen as a quantum fall from grace: When quantum bits, or qubits, are in superposition – such as a single qubit simultaneously having both 1 and 0 values ...

A quantum connection between light and motion
(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs ...

A quantum leap in computing
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.

Not all quantum properties are lost through interaction with the environment
(PhysOrg.com) -- One of the most well-known "rules" of quantum physics is that all quantum properties are lost due to environmental interaction. This rule, though, may not hold true in all situations. "We have discovered ...

New evidence for quantum Darwinism found in quantum dots
(PhysOrg.com) -- Physicists have found new evidence that supports the theory of quantum Darwinism, the idea that the transition from the quantum to the classical world occurs due to a quantum form of natural ...

Creating a six-qubit cluster state
(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 ...
