The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps ...

This proof-of-principle experiment marks an important advancement toward building large-scale ion-trap quantum computing ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet.

Ethereum co-founder Vitalik Buterin laid out a quantum resistance roadmap targeting four key vulnerabilities in the network’s cryptography.

Ethereum plans to cut block time to 2 seconds and finality to 16 seconds, with quantum resistance across seven forks by 2029.

This move comes shortly after the Ethereum Foundation established a dedicated post-quantum research team to study the issue.

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

Abstract: Quantum computing is rapidly emerging as a promising technology for solving complex optimization problems that arise in various engineering fields. Therefore, it holds significant promise to ...
