IBM hopes to demonstrate quantum advantage in 2026.
IBM achieved a milestone it calls "quantum utility" in 2023, the point where its quantum computer became challenging for a classical computer to simulate.
IBM is bringing a new 120-qubit device named Nighthawk online in 2026, which features higher connectivity with four connections per qubit instead of the previous three.
IBM's roadmap targets the availability of useful quantum error correction for users around the 2029 timeframe.
IBM developed an error-correcting code, called the Gross Code, which is an order of magnitude more efficient than previously known codes.
IBM's innovation roadmap includes demonstrating logical qubits in 2026, connecting logical qubit modules in 2027, and achieving universal computation on them in 2028.
IBM plans to offer error-corrected quantum devices to clients in 2029, merging its research and development roadmaps.
IBM's quantum computers operate with one end of their wiring at room temperature and the other end at 0.02 degrees above absolute zero.
IBM defines "quantum advantage" as the point where a quantum computer is used to do something better, faster, or cheaper than would have been possible on a classical computer.
Oliver Dial states that the scientific validity of Google's 2019 quantum supremacy claim is questionable due to an extrapolation step in verifying the results.
IBM helped establish the Quantum Advantage Tracker, a public leaderboard for comparing quantum and classical computer performance on specific problems.
IBM uses superconducting qubits, which are fabricated using the same tooling and processes as classical digital logic chips.
