Using a groundbreaking new technique, researchers have unveiled the first detailed image of a photon — a single particle of light — ever taken. When you purchase through links on our site, we may earn ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Quick, pick a side: Is light a wave or a particle? This question is best known for its power to set crowds of undergraduates a-tittering. But it’s more than a pop science brain-teaser. Scott Holmstrom ...

One approach to make qubits for quantum computing relies on the creation of two single photons that interfere with one another in a device called a waveguide. Results from a recent applied science ...

All wiring is beautiful, except when it isn’t. But is there anything more lovely to behold than circuit sculpture? Once again, [Mohit Bhoite] has made this process look easy like Sunday morning. This ...
