An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting superposition.

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems from classical interpretations. In quantum mechanics, particles exhibit ...

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 ...

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

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

Atomic gravimeters are used to accurately measure gravity by detecting the quantum interference patterns of freely falling atoms in a vacuum. However, these devices are typically bulky and complex, ...

Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré ...
