Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one perfectly, all the way down the line, producing an amazing result at the end. A quantum circuit is like a domino chain: a long chain of tiny steps ("operations") that work together to process information together in a powerful way.

Fujitsu quantum researcher Shinji Kikuchi discusses the quantum computing paradigm shift expected around 2030, as well as how business leaders should approach their preparation. Global technology company Fujitsu is leading Japan’s quantum computing revolution.

Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the quantum world

Quantum computing may still be regarded by many IT leaders as a very niche technology, but broader business use cases may be just a few years away. While only a handful of companies have machines with logical qubits today, delegates at the Commercialising ...

After the government's pledge to invest £2bn into quantum computing, how is the industry feeling?

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip into a "true" vacuum, unleashing a sweeping transformation.

Quantum decryption may still be years away, but small and midsize businesses can take practical steps today to protect sensitive data without overwhelming limited IT resources.

This team effort converges expertise to leverage quantum computing for an important, practical outcome.”— Marco Cerezo,
