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.
