Bell circuit with terminal measurements
Start in 00. Apply H to the first qubit, apply CX to both, then measure both at the end. The ideal circuit gives 00 or 11 with probability ½ each.
IBM Quantum · Documented fit
ibm_fez · Heron r2, configuration snapshot 1.2.8
IBM identifies ibm_fez as a gate QPU. Its documented basis includes SX, RZ, CZ and measurement. Compile the gates in the chosen preset for this exact backend target.
Check that your IBM Quantum instance exposes ibm_fez and supports the required instructions in its target. The October 2025 Open Plan entry is a dated provider announcement.
arn:aws:braket:eu-north-1::device/qpu/iqm/Garnet · IQM Garnet (Crystal 20), AWS examples at c260fafc
The provider’s Bell notebook demonstrates H and terminal measurement on Garnet through its ordinary compilation route. The CNOT in that notebook is specific to the Bell preset.
Verify access to the exact eu-north-1 device ARN. Confirm SDK support and current experimental conditions before attempting feedforward.
Start in 0, apply H, then measure. If that measurement returned 1, apply X in the same run. Measure again. Both ideal branches end with a final bit of 0.

ibm_fez · Heron r2, configuration snapshot 1.2.8
IBM identifies ibm_fez as a gate QPU. Its documented basis includes SX, RZ, CZ and measurement. Compile the gates in the chosen preset for this exact backend target.
IBM announced dynamic circuits on its cloud backends and lists measure, X and if_else in the ibm_fez configuration snapshot. The Qiskit guide documents this exact circuit. Confirm the live target and use a compatible runtime sampler path for the simple one-bit conditional.

The provider’s Bell notebook demonstrates H and terminal measurement on Garnet through its ordinary compilation route. The CNOT in that notebook is specific to the Bell preset.
AWS documents experimental measure_ff and conditional π rotation on Garnet. Use the experimental capability, a valid qubit group and the documented feedback key and ordering. The OpenQASM example adds a terminal measurement.

Advantage2_system1.6 · Advantage2; solver name documented, live graph ID unverified
Ocean documents a direct DWaveSampler route and names this solver in a native-graph example. Place the two interacting variables on an available edge or use the embedding interface.
Check your Leap project access and Ocean SDK 9.0 or newer for name-based identity selection. Select a working edge or use a valid embedding. The documentation’s example graph ID is historical.

A documented fit requires a physical QPU with the right execution model and documented support for every required operation. Each result applies to the named backend. Changing the circuit to add loops, nested conditions or a different optimization formulation calls for a separate check.
