At a glance
IBM unveiled its next-generation quantum computer chip, Nighthawk r3, at its annual Quantum Developer Conference (QDC 2026). It is scheduled for 2027, and IBM also plans to link two chips into a 1,040-qubit system.
Key points
Nighthawk r3 has 520 qubits, the basic units that hold quantum information.
Since September 2026, Nighthawk r2 chips have run more than 34 billion quantum circuits for partners.
Two chips will be connected to form a 1,040-qubit system.
IBM also introduced a managed workflow that lets classical and quantum computers work together in the cloud.
Why it matters
It signals that quantum computers are growing toward a size that could solve real problems in drug and materials research.
