This is a modern-day Manhattan Project, again a partnership between the U.K. and the U.S. The team behind Helios began in 2014 as Cambridge Quantum in England before joining with Honeywell Quantum Solutions, an arm of the U.S. industrial giant, to create Quantinuum. The field of quantum computing makes possible cracking encryption, creating innovative technologies, and discovering new drugs. Classical computers process information as ones or zeros in bits. A quantum computer uses qubits—shorthand for quantum bits—to harness the behavior of subatomic particles, which can exist in multiple states at once. That lets it explore vast numbers of possibilities simultaneously, a capability that could accelerate artificial intelligence development.
