1. A quantum computing system configured for removal of leakage states, the quantum computing system comprising:
quantum hardware comprising a first measurement qubit and a data qubit, wherein the first measurement qubit is configured to have a first transition frequency and wherein the data qubit is configured to have a second transition frequency, the first transition frequency being greater than the second transition frequency; and
one or more quantum control devices configured to control operation of at least the first measurement qubit and the data qubit, wherein the one or more quantum control devices are configured to implement a quantum gate operation on the first measurement qubit and the data qubit based at least in part on the first transition frequency and the second transition frequency, and wherein the one or more quantum control devices are configured to periodically reset a quantum state of the first measurement qubit.
