IonQ's growth is poised to accelerate nicely thanks to the cost and performance advantages of its quantum computing systems.

Researchers at the Indian Institute of Technology Bombay have proposed a new test to measure the “quantumness” of gravity after finding that conventional “quantum entanglement-based” tests may be ...

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 ...

Dr. Kimberley Hall’s Killam fellowship will accelerate her collaboration with NRC partners as they work to advance quantum ...

Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study ...

A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way of searching for dark-matter ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Optical feedback from on-chip components fundamentally limits stable laser operation in photonic integrated circuits. In a ...
