-    "These improvements brought by dynamic circuits, however, come with trade-offs. Mid-circuit measurements and classical operations typically have longer execution time than two-qubit gates, and this increase in time might negate the benefits of reduced circuit depth. Therefore, reducing the length of mid-circuit measurement is a focus area of improvement as IBM Quantum® releases the [new version](/announcements/product-updates/2025-03-03-new-version-dynamic-circuits) of dynamic circuits.  For other restrictions when using dynamic circuits, see the [Estimator](/docs/guides/estimator-options#options-compatibility-table) or [Sampler](/docs/guides/sampler-options#options-compatibility-table) Feature compatibility table.\n",

     "The [OpenQASM 3 specification](https://openqasm.com/language/classical.html#looping-and-branching) defines a number of control-flow structures, but Qiskit Runtime currently only supports the conditional `if` statement. In Qiskit SDK, this corresponds to the [if_test](/docs/api/qiskit/qiskit.circuit.QuantumCircuit#if_test) method on [QuantumCircuit](/docs/api/qiskit/qiskit.circuit.QuantumCircuit). This method returns a [context manager](https://docs.python.org/3/reference/datamodel.html#with-statement-context-managers) and is typically used in a `with` statement. This guide describes how to use this conditional statement.\n",
