When one of the crystals was very likely to emit photons, the pattern the interferometer produced was barely visible, implying that the photon was mostly particle-like. When the crystals’ emission ...

The team used an interferometer to split a photon wave function down two possible paths before meeting again.

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

Particle or wave? Chinese researchers used a modified version of the delayed-choice experiment (illustrated) to capture a photon morphing between wave and particle.

It says that a photon’s position is described by a mathematical abstraction called the wavefunction — which, as the name suggests, behaves like a wave.

The team found that the interaction of the droplet with its own waves is similar to a photon's quantum wave-particle behavior: When dropped into a configuration similar to what is proposed in the ...

By combining these two principles, the physicists produced a photon that appeared to simultaneously travel along and against the arrow of time. They published the results of their twin experiments ...
