Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny ...

Quantum dots, semiconductor nanostructures exhibiting discrete energy levels, have emerged as quintessential quantum emitters for on‐demand single-photon generation. Their unique confinement ...

Physicists have now teleported the quantum state of a single photon between distant quantum dots, turning a long theorized building block of the quantum internet into a working device. By reliably ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

The article was selected as a Featured Article in APL Quantum ("Approaching unity photon collection from NV centers via ultra-precise positioning of nanodiamonds in hybrid nanoantennas"). Diamonds ...

A long-standing bottleneck in photonic quantum technology may finally be easing. Researchers in Germany have demonstrated a deterministic photon source that operates in the telecom C-band while ...

Kyoto, Japan -- The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each ...
