Google's new whitepaper says it could take only minutes for a quantum system to crack Bitcoin.

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.

"I genuinely believe that quantum computing talent should be used for good," says Dr Carmen Palacios-Berraquero. The tech entrepreneur is echoing Chancellor Rachel Reeves, who recently called for "AI sovereignty" and warned artificial intelligence could be shaped by countries "whose values may differ from ours".

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing.
