A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical ...

Designed to accelerate advances in medicine and other fields, the tech giant’s quantum algorithm runs 13,000 times as fast as software written for a traditional supercomputer. A quantum computer at ...

“Today, we’re announcing research that shows — for the first time in history — that a quantum computer can successfully run a verifiable algorithm on hardware,” Google writes in a new blog post. The ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

IBM is unveiling IBM Quantum Nighthawk, its most advanced quantum processor yet and designed with an architecture to complement high-performing quantum software to deliver quantum advantage next year: ...

Bitcoin’s security relies on elliptic curve cryptography, a one-way mathematical function that makes deriving a private key from a public key effectively impossible for traditional computers. Shor’s ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

The dreaded Q-day could arrive sooner than expected, and when it does, experts say we need to be ready. Reading time 8 minutes In 1994, American mathematician Peter Shor developed a quantum algorithm ...
