A day later, IBM (IBM +1.51%) switched on its most advanced quantum computer in Chicago, powered by its Nighthawk chip.

It also reached Stage C of DARPA's Quantum Benchmarking Initiative and signed 16 enterprise quantum engagements this year, including one with General Motors (GM +0.24%).

IBM's Starling system, planned for 2029, is designed to run 100 million operations on 200 logical qubits.

Its next machine, Sol, is on track for the second half of 2027 and will be tuned toward 100 logical qubits.

Quantinuum is targeting 1 error per 100,000 operations at 100 logical qubits in late 2027.Hit it on time, and I'd keep adding.
