Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

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

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

A paradox at the heart of quantum physics has been tested in an extraordinary fashion, pushing the boundaries of human intuition beyond breaking point by measuring a pulse of light in 37 dimensions.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

A further benefit is that the channels can be multiplexed, allowing many quantum processors to access the system at the same ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

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 ...
