How can I convert an OpenQASM circuit to Q# and perform resource estimation?

Akita, Kosuke 0

I would like to convert a quantum circuit in OpenQASM format into a quantum circuit written in Q# and then perform resource estimation. What should I modify in the following code?
Alternatively, if there is another way, please let me know.

from qdk import TargetProfile
from qdk.openqasm import import_openqasm
from qdk import qsharp

# Set the QIR target profile
qsharp.init(target_profile=TargetProfile.Base)

qasm_code = """
    include "stdgates.inc";
    qubit[2] q;
    reset q;
    h q[0];
    cx q[0], q[1];
    bit c = measure q[1];
    """

import_openqasm(qasm_code, name="bell")

############################
GAP
############################

result_maj = qsharp.estimate("bell", params={
                "qubitParams": {
                    "name": "qubit_maj_ns_e6"
                },
                "qecScheme": {
                    "name": "floquet_code"
                },
                "errorBudget": 0.1})

EstimateDetails(result_maj)

Hello Akita,

Yes, this workflow is supported using the QDK Python APIs.

The main change needed is that import_openqasm() returns a callable circuit object, and that object should be passed directly to qsharp.estimate() instead of passing the operation name as a string.

So, after importing the OpenQASM circuit, store the returned object, for example:

bell_circuit = import_openqasm(qasm_code, name="BellCircuit")

Then use that callable in the estimator:

result = qsharp.estimate(bell_circuit, params=params)

instead of:

qsharp.estimate("bell", params=params)

Your current approach with TargetProfile.Base is acceptable for this workflow. You may also want to ensure that you are using the latest QDK packages, since OpenQASM import and resource estimation support can vary slightly between versions.

For additional guidance, please refer to the Microsoft documentation below:
