Rigetti plans $100M investment in the UK — its first major move outside the US.

Goal: deploy a 1,000+ qubit system in 3-4 years. Builds on existing 36-qubit deployment at the UK National Quantum Computing Centre.

Follows UK's £2B quantum initiative.

Yonsei, RIKEN & IBM link Fugaku supercomputer with Quantum System One to probe Leigh syndrome, a rare neonatal disease.

Solving it requires a ~1B x 1B matrix — ~30 years classically. Quantum-centric supercomputing takes aim.
