The disclosed techniques relate to validating and optimizing a quantum computing simulator. A quantum computing simulator executes a quantum executable file to obtain a first result. A second result is received from a quantum computer which also computes the quantum executable file. The hardware metadata associated with the quantum computer, and defining hardware conditions during a time in which the quantum executable file was executed to create the second result, is also received. In response to determining a difference between the first result and the second result, updated hardware metadata is created based on the received hardware metadata associated with the quantum computer. The quantum computing simulator performs a second execution of the quantum executable file based at least in part on the updated hardware metadata to obtain a third result.
