For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties ...

A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the ...

Physicists have now managed to track the passage of time inside a quantum event without using anything that looks like a ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a single chip and using “naturally occurring” qubits, she notes, reduces ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in single particles.

Quantum wells, fabricated through the precise layering of different semiconductor materials, create confined regions where charge carriers are restricted to two dimensions. This confinement gives rise ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist thanks to new research led by physicists at École Polytechnique Fédérale ...
