Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional ...

Quantum computers promise to simulate complex quantum field theories that are intractable for classical computers, potentially revealing new physics in strongly interacting systems. Current approaches ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

Cisco Systems Inc.’s new Universal Quantum Switch introduced last week is a strong proof point regarding the network’s importance in scaling quantum. For information technology leaders, the key ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is. Reading time 3 minutes The entire spiel of ...

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in ...

Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the ...

Dr. Niayesh Afshordi, professor at the University of Waterloo and Perimeter Institute, draws the renormalization group flow for quadratic quantum gravity (University of Waterloo). Waterloo scientists ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...
