IBM Unveils 1,121-Qubit 'Condor' Quantum Processor
IBM has announced Condor, a 1,121-qubit quantum processor - the first in the industry to surpass the 1,000-qubit milestone.
Technical Specifications
| Parameter | Condor | Previous (Osprey) | |-----------|--------|-------------------| | Qubits | 1,121 | 433 | | Qubit type | Transmon | Transmon | | Connectivity | Heavy-hex | Heavy-hex | | Coherence time | ~200µs | ~150µs | | Gate fidelity (2Q) | 99.9% | 99.8% |
Significance
Breaking the 1K Barrier
The 1,000-qubit threshold is widely considered the minimum for:
- Quantum error correction (surface codes need ~1,000 physical qubits per logical qubit)
- Utility-scale algorithms (chemistry, optimization, ML)
- Commercial viability for enterprise workloads
Roadmap Context
| Year | Processor | Qubits | Milestone | |------|-----------|--------|-----------| | 2021 | Eagle | 127 | First 100+ qubit | | 2022 | Osprey | 433 | First 400+ qubit | | 2023 | Condor | 1,121 | First 1,000+ qubit | | 2024 | Flamingo | 1,386+ | Modular architecture | | 2025 | Kookaburra | 4,158+ | Multi-chip linking |
Quantum System Two
Condor debuts in IBM Quantum System Two, featuring:
- Modular, cryogenic architecture
- Classical control electronics integration
- Support for multi-chip coupling
- Designed for quantum-centric supercomputing
Error Correction Progress
IBM also demonstrated:
- Dynamic circuits - real-time classical computation during quantum execution
- Error suppression - 10x improvement via dynamical decoupling
- Logical qubit prototype - 12 physical qubits → 1 logical qubit (early stage)
Industry Reaction
Dr. Jay Gambetta, IBM Fellow: "Condor isn't just about qubit count - it's about building a system where every component scales. System Two is the first quantum computer designed for the error-corrected era."
Competitors (Google, Rigetti, IonQ) are pursuing different architectures but acknowledge the milestone.
Availability

- Commercial: General availability 2025
Key Takeaways
- First 1,000+ qubit quantum processor
- Enables quantum error correction research
- Debuts in modular System Two architecture
- Roadmap targets 4,000+ qubits by 2025
Frequently Asked Questions
Can I run algorithms on Condor now?
IBM Quantum Network members get cloud access in Q4 2024.
Is 1,121 qubits enough for practical applications?
Not yet for most - error correction needs ~1,000 physical qubits per logical qubit. But it's the critical threshold.
How does this compare to Google's quantum computer?
Google's Sycamore has 70 qubits but different architecture. Qubit count isn't directly comparable across modalities.
