Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to determining estimated energy relaxation times of qubits. A system can comprise a memory configured to store computer executable components; and a processor configured to execute the computer executable components stored in the memory, wherein the computer executable components comprise a sampling component configured to sample a plurality of measurements of an energy relaxation time of a qubit at individual shifted qubit frequencies of a plurality of shifted qubit frequencies of the qubit; and an analysis component configured to perform an analysis, based on a protocol, to determine a correlation frequency-length between individual energy relaxation times measured at the individual shifted qubit frequencies.

Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to analysis of qubit coherence parameters of a physical qubit layout of a quantum computer. A system can comprise a pulse component for transmitting signals to a qubit, a readout component for receiving signals form the qubit, a memory that stores computer executable component, and a processor that executes the computer executable components stored in the memory. The computer executable components are executable to cause the pulse component to generate a first pulse to drive the qubit, cause the pulse component to generate a second pulse comprising an Autler-Townes off-resonant tone, and determine a probability relative to the qubit, in view of a shift of the qubit to a shifted frequency caused by the second pulse.

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.
