A specially tweaked classical computer system has just solved a physics problem so complex it was thought to be impossible without a quantum computer. The problem is the simulation of what are called ...

Toronto-based Xanadu Quantum Technologies published a new algorithmic optimization on May 21 that halves the Toffoli gate ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

Google claims to have developed a quantum computer algorithm that is 13,000 times faster than the most powerful supercomputers. This would bring the technology another step closer to real-world ...

Quantum technologies like quantum computers are built from quantum materials. These types of materials exhibit quantum properties when exposed to the right conditions. Curiously, engineers can also ...

Researchers from the group of theoretical physicist Hans Briegel have collaborated with NVIDIA to develop an AI method that automatically generates efficient quantum circuits, a key bottleneck in ...

For nearly 30 years, the cybersecurity community has known that a quantum computer of sufficient size and sophistication—if such a machine were ever built—could be used to undermine the security of ...

A new report by Capgemini warns that quantum computing may break the widely used public-key cryptographic systems within the next decade — threatening everything from online banking to blockchain ...

Somewhere on a blockchain right now, a Bitcoin address that last moved coins in 2015 is sitting with its public key fully exposed, waiting for its owner to return. That owner may have years to act, or ...

Zero-trust frameworks play a large role in modern security. However, they must progress alongside cryptographic defenses to protect against threats surpassing traditional access control.
