IBM has launched its first Quantum Nighthawk processor, IBM_Miami, featuring the highest T1 coherence times of any IBM quantum processor, averaging around 350 µs. The IBM_Miami, which follows the IBM_Pittsburgh QPU, is available in an early-access preview through IBM's Premium and Flex plans.

It boasts 120 qubits and 218 next-generation tunable couplers, enhancing qubit connectivity by 20% compared to the Quantum Heron chip, allowing for 30% more complex circuit execution. The Nighthawk chip can execute 5,000 two-qubit gates in a single quantum circuit, with future versions expected to increase this capability to 7,500 gates by 2026 and 10,000 gates by 2027. IBM aims to achieve quantum advantage by the end of 2026 and develop a fault-tolerant quantum computer by 2029.
