Premium systems now support mid-circuit measurement and qubit re-use!

Mid-circuit measurement (requires Qiskit Terra 0.16.1 or later) makes it possible to measure an individual qubit at any point in the circuit, not just at the end. You can also measure qubits multiple times within a circuit. Measurements can be triggered independently.

In conjunction with Conditional Reset on IBM Quantum Systems (opens in a new tab), you can now re-use qubits. This opens up the opportunity for a wider variety of experiments, such as

• heralding
• monitoring qubit evolution
• multiple measurement of ancilla qubits for post selection

For more information, see the Mid-Circuit Measurements Tutorial (opens in a new tab) in the docs.
