US 12,608,441 B2 · Screening for fluctuating energy relaxation times

Abstract

One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to determining estimated true relaxation times of qubits absent measurement of entire T1 decay times of the qubits. A system can comprise a memory that stores computer executable components; and a processor that executes the computer executable components stored in the memory, wherein the computer executable components are executable to cause, by the processor, one or more energy relaxation measurements, using a pulse generation, at the qubit frequency for a qubit and at a plurality of shifted frequencies for the qubit, and to determine, by the processor, a true average relaxation time of the qubit based on the plurality of energy relaxation measurements.
