Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Chinese scientists have for the first time directly observed the Migdal effect in neutron-nucleus collisions in an experiment ...

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...
