Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

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?

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

"These single atoms are like the smallest slits you could possibly build." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. For over 100 years, ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the true limits of light’s wave–particle duality. Their results proved ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the particle nature of dark matter." When you purchase through links on our site, we ...

Light scattering techniques have emerged as a powerful set of non‐invasive optical methods for the analysis of cells and particulate matter. By measuring and interpreting the patterns of light ...

The CERN has recently submitted a preliminary report (FCC) proposing the design of a future particle accelerator with a 100 km circumference. If realized, this ...

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 ...
