Shor’s Algorithm Breaks 5-bit Elliptic Curve Key on 133-Qubit Quantum Computer
Researchers successfully cracked a standard encryption key using a quantum computer, demonstrating a significant step towards breaking widely used digital security protocols with a 133-qubit processor and a novel approach to extracting the secret key without directly encoding it.
Tippeconnic from Arizona State University and colleagues successfully break a 5-bit elliptic curve cryptographic key, a fundamental component of many security systems, using a 133-qubit quantum computer. This experiment, performed on an IBM quantum processor, demonstrates the ability to solve a cryptographic problem with a relatively small number of qubits and a surprisingly deep circuit, paving the way for further research into quantum-resistant cryptography. The approach used modular arithmetic techniques to encode the problem without directly referencing the secret key, and visualization of the results confirmed the expected quantum interference patterns.
