IBM and University of Chicago Demonstrate Verified Logical Quantum Computation Beyond Classical Simulation

Researchers from IBM and the University of Chicago have successfully demonstrated a logical quantum computation that surpasses the capabilities of classical simulation methods, while also verifying the accuracy of the results¹. This achievement was made possible by utilizing encoded quantum circuits comprising 70 logical qubits, which enabled the completion of thousands of logical operations with reduced effective error rates compared to the underlying physical qubits. The experimental data and circuits have been made publicly available through the Quantum Advantage Tracker, facilitating further analysis and benchmarking. This breakthrough has significant implications for the field of quantum computing, as it underscores the growing need for organizations to migrate to post-quantum cryptography. The demonstration of verified logical quantum computation beyond classical simulation capabilities accelerates the urgency for practitioners to develop and implement quantum-resistant cryptographic solutions, as the threat of quantum computing to current cryptographic standards becomes increasingly imminent.
