bloqade.qasm2.passes.parallel.UOpToParallel

Bases: Pass

Pass to convert single gates into parallel gates.

Signature

class UOpToParallel(merge_policy_type: Type[MergePolicyABC] = SimpleOptimalMergePolicy, rewrite_to_native_first: bool = False)

Public import paths

• from bloqade.qasm2.passes import UOpToParallel

This pass looks for single gates from the qasm2.uop dialect that can be combined into parallel gates from the qasm2.parallel dialect and performs a rewrite to do so.

Usage Examples

# Define kernel
@qasm2.main
def test():
    q = qasm2.qreg(4)

    theta = 0.1
    phi = 0.2
    lam = 0.3

    qasm2.u(q[1], theta, phi, lam)
    qasm2.u(q[3], theta, phi, lam)
    qasm2.cx(q[1], q[3])
    qasm2.u(q[2], theta, phi, lam)
    qasm2.u(q[0], theta, phi, lam)
    qasm2.cx(q[0], q[2])

# Run rewrite
UOpToParallel(main.dialects)(main)

The individual qasm2.u statements have now been combined into a single qasm2.parallel.u statement.

qasm2.parallel.u(qargs = [q[0], q[1], q[2], q[3]], theta, phi, lam)
qasm2.uop.CX(q[1], q[3])
qasm2.uop.CX(q[0], q[2])
