Quantum physics: Ménage à trois photon-style

Entanglement is one of the properties specific to quantum particles. When two photons become entangled, for instance, the quantum state of the first will correlate perfectly with the quantum state of the second, even if they ...

2-D topological physics from shaking a 1-D wire

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong ...

Can neutrinos help explain what's the matter with antimatter?

In physics, antimatter is simply the "opposite" of matter. Antimatter particles have the same mass as their counterparts but with other properties flipped; for example, protons in matter have a positive charge while antiprotons ...

Entanglement sent over 50 km of optical fiber

The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology. However, because quantum information cannot be copied, it is not possible to send this ...

Scientists discover new state of matter

A team of physicists has uncovered a new state of matter—a breakthrough that offers promise for increasing storage capabilities in electronic devices and enhancing quantum computing.
