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

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

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

As quantum computing evolves from theory to commercialization, two distinct visions are emerging. Rigetti Computing RGTI and D-Wave Quantum Inc. QBTS represent divergent paths toward unlocking quantum ...
