调研方向

Start from the reproducer in the issue: the bell_state example using aq.verbatim() and to_ir(), which currently drops the pragma braket verbatim block during OpenQASM 3 to QIR translation. The payload does not name the source files, so locate the translation code by searching for the verbatim or pragma handling. Done means either the pragma survives translation with a test covering it, or a documented finding on why QIR cannot carry it.

描述

duplicate enhancement
Feature Description

In autoqasm, you use the aq.verbatim() context to instruct the compiler to avoid modifying anything inside the block. For example:

@aq.main
def bell_state():
    with aq.verbatim():
        ins.h("$0")
        ins.cnot("$0", "$1")
    return ins.measure(["$0", "$1"])

print(bell_state.build().to_ir())

This program now targets physical qubits, and the gates will not be modified by the compiler. And the ir looks like this:

OPENQASM 3.0;
output bit[2] return_value;
pragma braket verbatim
box {
    h $0;
    cnot $0, $1;
}
bit[2] __bit_0__ = "00";
__bit_0__[0] = measure $0;
__bit_0__[1] = measure $1;
return_value = __bit_0__;

To support aq.verbatim(), we need support for openqasm3 pragma, which we are unsure if QIR supports or not. Either find a way to support pragma in the openqasm3 to qir translation or determine that is not possible.
