Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be directly controlled and observed in real time. The achievement pushes the ...

As the quantum computing debate heats up, Bitcoin developers and venture capitalists are clashing over the future of crypto ...

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...

Quantum computing invites us to embrace uncertainty as a powerful tool to advance our goals, and the industry at large today reflects a peculiarly similar position. At QuEra, we recently conducted a ...

In quantum mechanics, it is impossible to know both exactly where you are and exactly where you are going. This idea, known as Heisenberg’s uncertainty principle, has been a key part of studying the ...

The uncertainty principle, proposed by Werner Heisenberg nearly a century ago, has remained a central pillar of quantum mechanics, dictating that certain properties of light and matter cannot be ...

As a trained physicist and now a university president, I am doubly excited by the acceleration in quantum computing and the possibilities quantum thinking offers for elevated understanding, innovation ...

Researchers from the University of Arizona, working with an international team, have captured and controlled quantum uncertainty in real time using ultrafast pulses of light. Their discovery, ...

Quantum computing remains years away, but it is already shaping how blockchains prepare and how investors view Bitcoin’s long-term security.

The downside is that the physics and engineering needed to make them work has only just moved out of the theoretical realm and into reality.

Scientists generated ultrafast light pulses with controllable, real-time quantum uncertainty, visualizing Heisenberg’s ...
