Dynamic circuits are powerful tools that give us the ability to measure qubits in the middle of a quantum circuit execution, and then perform classical logical operations within the circuit based on the outcome of those mid-circuit measurements. All of this occurs in the blink of an eye, before the circuit execution is complete, allowing us to take creative approaches to solving problems with quantum computation. These capabilities will be essential for the modular quantum computing architectures and quantum error correction protocols of the future. However, we still have a lot of work to do to explore their full potential.In a recent blog post, we saw how IBM researchers used dynamic circuits to share the statistics of entanglement over a classical communications channel, enabling the implementation of virtual two-qubit gates between qubits on separate quantum processors. However, the usefulness of dynamic circuits doesn’t end there. A paper published in PRX Quantum by other IBM researchers shows how dynamic circuits can enable efficient long-range entanglement between qubits on the same chip using shallow circuits.
