Replacing the crystal used for generating entangled photons can significantly increase quantum imaging contrast.

Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly ...

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 photon separately ...

Photonic-based qubits and integrated photonic circuits have enabled demonstrations of quantum information processing (QIP) that promises to transform the way in which we compute and communicate. To ...

As quantum computers continue to evolve significantly 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18, there arises a fundamental need for a communication network that provides unconditionally secure ...

Chaotic speckle: a pattern resulting from light being scrambled by a complex medium such as a multimode optical fibre. (Courtesy: M Malik and S Goel) Light passing through a disordered (or “complex”) ...

Watch a difficult sea turtle rescue as two fishermen works to free an entangled animal in need. See how the turtle reacts ...

Rescuers are looking for an entangled sea creature after it disappeared soon after being spotted in an Alaska inlet, federal officials said. On Oct. 1, Protected Species Observers working along the ...
