Cirq conversions

Example Usage

Convert a Cirq circuit to QIR code:

import cirq
from qbraid_qir import dumps
from qbraid_qir.cirq import cirq_to_qir

# create a test circuit
q0, q1 = cirq.LineQubit.range(2)
circuit = cirq.Circuit(cirq.H(q0), cirq.CNOT(q0, q1), cirq.measure(q0, q1))

# convert to QIR
module = cirq_to_qir(circuit, name="bell")

# saves to .ll and .bc files in working directory
dumps(module)

print(module)

; ModuleID = 'bell'
source_filename = "bell"

%Qubit = type opaque
%Result = type opaque

define void @main() #0 {
entry:
  call void @__quantum__qis__h__body(%Qubit* inttoptr (i64 0 to %Qubit*))
  call void @__quantum__qis__cnot__body(%Qubit* inttoptr (i64 0 to %Qubit*), %Qubit* inttoptr (i64 1 to %Qubit*))
  call void @__quantum__qis__mz__body(%Qubit* inttoptr (i64 0 to %Qubit*), %Result* inttoptr (i64 0 to %Result*))
  call void @__quantum__qis__mz__body(%Qubit* inttoptr (i64 1 to %Qubit*), %Result* inttoptr (i64 1 to %Result*))
  ret void
}

declare void @__quantum__qis__h__body(%Qubit*)
declare void @__quantum__qis__cnot__body(%Qubit*, %Qubit*)
declare void @__quantum__qis__mz__body(%Qubit*, %Result* writeonly) #1

attributes #0 = { "entry_point" "output_labeling_schema" "qir_profiles"="custom" "required_num_qubits"="2" "required_num_results"="2" }
attributes #1 = { "irreversible" }

!llvm.module.flags = !{!0, !1, !2, !3}
!0 = !{i32 1, !"qir_major_version", i32 1}
!1 = !{i32 7, !"qir_minor_version", i32 0}
!2 = !{i32 1, !"dynamic_qubit_management", i1 false}
!3 = !{i32 1, !"dynamic_result_management", i1 false}

Note

Circuits constructed using qubits of type cirq.NameQubit or cirq.GridQubit will be transformed to type cirq.LineQubit before conversion to QIR.

Execute the QIR program using the qir-runner command line tool:

$ qir-runner -f bell.bc
