IBM has introduced two different quantum chips that it believes could help demonstrate “quantum advantage,” or the ability for a quantum computer to solve a problem faster than a classical computer, by the end of 2026. The new chips, Nighthawk and Loon, should help do that by taking different approaches to connecting qubits in a quantum computer, producing fewer errors and supporting more complex computations.
Of the two new chips, IBM Quantum Nighthawk is the one the company believes it can iterate on to produce quantum advantage. By the end of 2025, the version of Nighthawk IBM will provide to its partners will have “120 qubits linked together with 218
