IBM’s Quantum Leap Threatens Bitcoin Security
- IBM researchers have successfully entangled a record-breaking 120 qubits, marking a significant advancement in quantum computing.
- The GHZ “cat state” achieved a fidelity of 0.56, confirming full multi-qubit entanglement and advancing toward fault-tolerant quantum systems.
- Direct Fidelity Estimation was used to verify results, offering scalable quantum verification methods.
- IBM’s breakthrough poses potential risks to Bitcoin security, as future quantum computers could theoretically crack its encryption.
IBM’s achievement in creating a stable and large-scale entangled qubit state represents a leap forward in quantum computing capabilities, edging closer to systems that might threaten digital asset security like Bitcoin’s encryption.
With IBM targeting fault-tolerant systems by the end of the decade, the timeline for potential threats to digital assets is becoming increasingly tangible, underscoring the need for vigilance in cryptographic security measures. (Source)
