IBM’s quantum computing programme is the most advanced and publicly documented in the world — and it represents the most precise way to track how close we are to a quantum threat against Bitcoin. In 2026, IBM’s quantum computer programme operates systems with over 1,000 physical qubits and has published a roadmap to millions of qubits within this decade. Here is the current IBM quantum status and what it means for Bitcoin security.
IBM has operated a consistent public quantum roadmap since 2020. Key milestones: 2021 — Eagle (127 qubits), 2022 — Osprey (433 qubits), 2023 — Condor (1,121 qubits) and Heron (133 qubits, improved connectivity), 2024 — continued Heron family scaling and error correction improvements, 2025-2026 — IBM targets fault-tolerant logical qubit demonstrations. IBM’s stated goal is to demonstrate 100 error-corrected logical qubits capable of useful computation by 2026-2028. Each logical qubit for Bitcoin-breaking purposes requires approximately 1,000 physical qubits at current error rates.
Breaking 256-bit ECDSA (Bitcoin’s signature scheme) requires approximately 4,000 error-corrected logical qubits running Shor’s algorithm. At current physical-to-logical qubit ratios (~1,000:1), that means approximately 4 million physical qubits. IBM’s 2026 systems: ~1,000-5,000 physical qubits. IBM’s 2033 projected systems: millions of physical qubits on quantum-centric supercomputer architecture. The gap is closing. It is not yet closed.
| Year | IBM System | Physical Qubits | Logical Qubits (est.) | Bitcoin Breaking % |
|---|---|---|---|---|
| 2023 | Condor | 1,121 | ~1 | <0.1% |
| 2025 | Heron family | ~5,000 | ~5 | ~0.1% |
| 2028 est. | Kookaburra / Flamingo | ~100,000 | ~100 | ~2.5% |
| 2031-2033 est. | Quantum-centric supercomputer | ~1,000,000+ | ~1,000+ | ~25%+ |
| 2033-2036 est. | Full fault-tolerant CRQC | ~4,000,000 | ~4,000 | 100% — Bitcoin ECDSA breakable |
The HNDL attack does not need Bitcoin to be breakable today. State actors with intelligence that IBM’s 2033-2036 projection is accurate are archiving Bitcoin blockchain data right now. Every Bitcoin public key ever broadcast is being stored for the day when IBM or another programme reaches CRQC capability. The collection phase is present-tense regardless of when decryption becomes possible.
BMIC’s CRYSTALS-Kyber and CRYSTALS-Dilithium provide full security even against a mature CRQC on IBM’s most aggressive timeline. NIST evaluated these algorithms against hypothetical quantum computers far more powerful than IBM’s current or near-term roadmap. The MLWE lattice problem on which both algorithms are based has no known quantum speedup — IBM’s quantum computers, at any projected scale, cannot efficiently solve it. Presale $0.049999.
Can IBM’s quantum computer break Bitcoin?
Not yet. IBM’s 2026 systems have ~1,000-5,000 physical qubits. Breaking Bitcoin requires ~4 million. Timeline to CRQC: 2031-2036 on IBM’s current roadmap.
When will IBM have a quantum computer powerful enough to break Bitcoin?
IBM’s quantum-centric supercomputer programme targets millions of physical qubits by the early 2030s. Expert consensus: CRQC capability against Bitcoin by 2031-2036.
How does IBM’s quantum progress affect crypto investors now?
Harvest-now-decrypt-later attacks are already collecting blockchain data based on the IBM timeline. The time to migrate to quantum-safe crypto (BMIC) is now — before the CRQC arrives, not after.
Is BMIC safe from IBM quantum computers?
Yes. CRYSTALS-Kyber and Dilithium are based on MLWE — no IBM quantum algorithm can efficiently solve it. NIST confirmed this after seven years of global evaluation.
