MITIGATION OF QUBIT DECOHERENCE IN QUANTUM COMPUTING AND INFORMATION PROCESSING SYSTEMS

Resumen de: US20260350457A1

The ability to employ a qubit for computation and/or information processing is fragile. A qubit is employable for calculation purposes only when the qubit is in “coherence” with other qubits of the quantum computation system and isolated from other elements of the universe. Temperatures near absolute zero are often required for such isolation. Heat, as well as other conditions may cause a qubit to become decohered and “entangled” with other elements of the universe. The invention mitigates adverse issues associated with qubit decoherence in quantum computing and information processing systems. During the execution of a quantum computation, the utilized qubits are monitored for signatures indicating qubit decoherence and/or likely decoherence. Rising heat and/or temperature of a qubit may be one signal of decoherence. During the calculation, when a qubit is determined to be anomalous, the invention “swaps-out” the anomalous qubit and “swaps-in” a non-anomalous qubit.

The updated configurations are transmitted to the quantum hardware for execution. The method can then receive experimental expectation values corresponding to the different numbers of circuit foldings. Then, an error-mitigated expectation value is determined by applying an extrapolation between the experimental expectation values and the corresponding circuit folding numbers.
