IBM unveils Eagle, a 127-qubit processor

IBM/Starling fault-tolerant roadmap

IBM announced Eagle, a 127-qubit superconducting processor, at its 2021 Quantum Summit. Eagle marks the first IBM quantum processor with more than 100 operational and connected qubits, and is the first whose scale makes it impossible for a classical computer to reliably simulate its quantum state.

• 127-qubit superconducting processor; first IBM system with 100+ connected operational qubits.
• Control wiring placed on multiple physical levels within processor while keeping qubits single layer—enables density without overhead.
• Quantum state complexity exceeds atoms in 7.5 billion people—beyond classical simulation.
• Available to IBM Quantum Network members for exploration of ML optimization, molecular/material modeling for energy, pharma.
