A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be ...

Controlling quantum states with high precision—and entangling particles—has long been the goal of researchers pushing the boundaries of quantum technology. Although great strides have been made across ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, ...
