qbraid.transpiler.cirq_braket.convert_from_braket_qasm module

Module for converting Braket circuits to Cirq circuit via OpenQASM

from_braket(circuit)[source]

Returns a Cirq circuit equivalent to the input Braket circuit.

Note: The returned Cirq circuit acts on cirq.LineQubit’s with indices equal to the qubit indices of the Braket circuit.

Parameters: circuit (Circuit) – Braket circuit to convert to a Cirq circuit.
Raises: CircuitConversionError – if circuit could not be converted
Return type: Circuit

qbraid.transpiler.cirq_braket.convert_from_braket module

Module for converting Cirq circuits to Braket circuits

unitary_braket_instruction(instr)[source]

Converts a Braket instruction to a unitary gate instruction.

Parameters: instr (Instruction) – Braket instruction to convert.
Raises: CircuitConversionError – If the instruction cannot be converted
Return type: Instruction

from_braket(circuit)[source]

Returns a Cirq circuit equivalent to the input Braket circuit.

Note: The returned Cirq circuit acts on cirq.LineQubit’s with indices equal to the qubit indices of the Braket circuit.

Parameters: circuit (Circuit) – Braket circuit to convert to a Cirq circuit.
Return type: Circuit

qbraid.transpiler.cirq_braket.convert_to_braket module

Module for converting Braket circuits to Cirq circuits

to_braket(circuit)[source]

Returns a Braket circuit equivalent to the input Cirq circuit.

Parameters: circuit (Circuit) – Cirq circuit to convert to a Braket circuit.
Return type: Circuit
Returns: Braket circuit equivalent to the input Cirq circuit.

qbraid.transpiler.cirq_braket.custom_gates module

Module for Braket custom gates

class C(sub_gate, targets)[source]

Bases: Gate

Controlled gate :type sub_gate: Gate :param sub_gate: Quantum Gate. :type sub_gate: Gate :type targets: QubitSet :param targets: Target qubits. :type targets: QubitSet

Parameters

qubit_count (Optional[int]) – Number of qubits this gate interacts with.
ascii_symbols (Sequence[str]) – ASCII string symbols for the gate. These are used when printing a diagram of circuits. Length must be the same as qubit_count, and index ordering is expected to correlate with target ordering on the instruction. For instance, if CNOT instruction has the control qubit on the first index and target qubit on the second index. Then ASCII symbols would have [“C”, “X”] to correlate a symbol with that index.

Raises

ValueError – qubit_count is less than 1, ascii_symbols are None, or ascii_symbols length != qubit_count

to_matrix(*args, **kwargs)[source]

Returns a matrix representation of the quantum operator

Returns: A matrix representation of the quantum operator
Return type: np.ndarray

adjoint()[source]

Returns a list of gates that implement the adjoint of this gate.

This is a list because some gates do not have an inverse defined by a single existing gate.

Returns: The gates comprising the adjoint of this gate.
Return type: List[Gate]

static c(targets, sub_gate)[source]

Registers this function into the circuit class. :type targets: QubitSet :param targets: Target qubits. :type targets: QubitSet :type sub_gate: Gate :param sub_gate: Quantum Gate. :type sub_gate: Gate

Returns: Controlled Gate Instruction.
Return type: Instruction
