How Does This Quantum Experiment Impact Bitcoin’s Encryption?
IBM’s quantum experiment pushes the boundaries of entanglement by generating a Greenberger–Horne–Zeilinger (GHZ) state, often referred to as a “cat state,” where all 120 qubits exist in a superposition of zero and one simultaneously. This state is highly sensitive to imperfections, making it an ideal benchmark for quantum platforms like superconducting circuits, as noted in the research. The team employed an adaptive compiler to route operations through the least noisy parts of the chip and used temporary uncomputation to stabilize qubits, achieving a fidelity score of 0.56—above the 0.5 threshold that confirms full quantum coherence.
Verification relied on parity oscillation tests and Direct Fidelity Estimation, sampling stabilizers to ensure qubit synchronization without exhaustive computation, which would be infeasible for 120 qubits. While current systems lack the power to directly threaten cryptography, this stability marks progress toward scalable quantum machines. For Bitcoin, the implications are profound: quantum algorithms like Shor’s could factor large numbers exponentially faster than classical computers, potentially exposing public keys and allowing fund theft from vulnerable addresses.

Project 11, a quantum computing research group, estimates that 6.6 million BTC—approximately 31% of the total supply and worth about $767.28 billion—are at risk because their public keys are already exposed. This includes coins held by Bitcoin’s pseudonymous creator, Satoshi Nakamoto. Alex Pruden, founder of Project 11, emphasized in a statement to COINOTAG, “This is one of Bitcoin’s biggest controversies: what to do with Satoshi’s coins. You can’t move them, and Satoshi is presumably gone. So what happens to that Bitcoin? It’s a significant portion of the supply. Do you burn it, redistribute it, or let a quantum computer get it? Those are the only options.”
The broader context includes intensifying competition among tech giants. IBM’s achievement eclipses Google’s recent 105-qubit Willow chip, which performed a physics simulation faster than any classical supercomputer. Other players like Quantinuum are also advancing toward fault-tolerant systems, with IBM aiming for practical implementations by 2030. These developments underscore the need for the cryptocurrency industry to prepare through quantum-resistant algorithms, such as those being explored in Bitcoin Improvement Proposals.

Quantum states like GHZ have applications beyond cryptography threats; they enable quantum sensing at the Heisenberg limit, the theoretical maximum precision for measurements. Historically, such states have benchmarked diverse platforms, from trapped ions to photons, highlighting their versatility. IBM’s use of noise-suppressed circuits ensures the entanglement remains viable, a step essential for error-corrected quantum computing where logical qubits can operate reliably despite physical imperfections.
In practical terms, building larger entangled states addresses a core challenge: decoherence, where quantum information degrades due to environmental noise. By disentangling and recomputing qubits temporarily, IBM mitigated this, scaling from smaller demonstrations to 120 qubits without proportional fidelity loss. This methodological innovation could accelerate progress in quantum error correction, vital for running complex algorithms on noisy hardware.
Frequently Asked Questions
What Makes IBM’s 120-Qubit Entanglement a Threat to Bitcoin Security?
IBM’s 120-qubit entanglement creates a stable, multipartite quantum state that advances fault-tolerant computing, potentially enabling Shor’s algorithm to break Bitcoin’s elliptic curve cryptography. This could allow reconstruction of private keys from exposed public keys, risking theft of dormant funds. While not immediate, it signals the urgency for the crypto community to adopt post-quantum signatures to safeguard assets.
Is Quantum Computing Ready to Crack Bitcoin Encryption Today?
No, current quantum systems like IBM’s 120-qubit experiment are not powerful enough to crack Bitcoin’s encryption, which requires millions of stable qubits for practical attacks. However, the demonstrated fidelity of 0.56 in GHZ states shows rapid progress toward scalable machines. Bitcoin users should monitor developments and consider quantum-safe wallets for long-term protection, as threats may emerge within the next decade.
