Amazon Braket adds dynamic circuit capabilities on IQM Garnet

Today, Amazon Braket introduced experimental support for dynamic circuits on IQM's Garnet quantum processing unit (QPU). This capability enables mid-circuit measurements (MCM) and feed-forward operations, allowing quantum researchers and developers to implement more advanced quantum algorithms. Dynamic circuits are a key building block for quantum error mitigation and correction. They can improve resource efficiency via qubit reuse, as well as enable experimentation with algorithms and protocols that require conditional logic.

With dynamic circuits, customers can now perform active qubit reset to reuse qubits within a single circuit execution and apply conditional operations based on measurement outcomes. These techniques can reduce circuit depth requirements unlocking new capabilities on Amazon Braket.

To use dynamic circuits, customers can submit verbatim programs that include mid-circuit measurement and conditional rotation instructions. These programs can be written using using OpenQASM, the Amazon Braket SDK, or the Amazon Braket Qiskit Provider. This experimental capability is available to all customers using an IQM device in the Europe (Stockholm) Region without requiring any special access permissions.
