In quantum mechanics, particles can exist in multiple states at the same time, defying the logic of everyday experiences. This property, known as quantum superposition, is the basis for emerging ...

At Princeton University in the early 1970s, the celebrated theoretical physicist John Wheeler could be spotted in seminars or impromptu hallway discussions drawing a big “U.” The letter’s left tip ...

(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 ...

Researchers have discovered how to quiet environmental decoherence, a major obstacle to realizing the enormous potential of quantum computing. Researchers have made a major advance in predicting and ...

Why do we not see everyday objects in quantum superpositions? The answer to that long-standing question may partly lie with gravity. So says a group of physicists in Austria, which has shown ...

Topological defects are the epitome of locality. An example of a defect occurs in the quantum Ising model where a lattice of spins interact ferromagnetically with their nearest neighbours, that is, ...

Rochester researchers have reported a strategy to understand how quantum coherence is lost for molecules in solvent with full chemical complexity. The findings open the door to the rational modulation ...
