For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

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

Scientists have developed a new way to manufacture semiconductor quantum dots that emit faster ...

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 ...

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 ...

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 ...

A series of experiments across multiple research groups has shown that deliberately implanting atomic-scale defects into ordinary silicon can turn the world’s most common semiconductor into a source ...

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 ...

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 ...
