to_openqasm(qubit_prefix='q')

Convert the current operation into an OpenQASM statement.

示例

H -> h q[0]; RX(pi/2) -> rx(pi/2) q[1]; CX(0, 1) -> cx q[0], q[1];

参数:: qubit_prefix (str) -- The prefix used for qubit identifiers in the output QASM code (e.g., "q" results in q[0], q[1], ...).
返回:: A formatted OpenQASM instruction string.
返回类型:: str
抛出:: ValueError -- If the operation contains no target qubits.

wy_qcos.common.cmss.circuit_instruction module

class wy_qcos.common.cmss.circuit_instruction.CircuitInstruction(operation, qubits, clbits=None)

基类：object

电路中的单条指令，对应 QuantumCircuit.instructions 中的元素.

对应 qiskit QuantumCircuit.data 字段。

实例包含三个核心字段：operation 表示门操作对象，需具备 .name、.params、.duration 属性；qubits 为该指令作用的量子比特索引列表；clbits 为该指令关联的经典比特索引列表，主要用于测量门。

参数:

qubits (list)
clbits (list | None)

operation

qubits

clbits

wy_qcos.common.cmss.delay module

Circuit-level Delay instruction.

class wy_qcos.common.cmss.delay.Delay(duration, unit='dt', name='delay')

基类：BaseOperation

Delay instruction that idles a qubit for a specified duration.

property duration: Return the duration of the delay.

property unit: Return the time unit of the duration.

property params: Return instruction params.

wy_qcos.common.cmss.duration module

Duration conversion utilities for quantum circuits.

wy_qcos.common.cmss.duration.convert_durations_to_dt(circuit, dt_in_sec=None, inplace=False)

Convert instruction durations from SI units to dt units.

Converts the duration of each instruction in the circuit from its current time unit to the backend's dt (sample time) unit.

参数:

circuit -- The QuantumCircuit to convert.
dt_in_sec -- The duration of one dt in seconds.
inplace -- If True, modify the circuit in place. Otherwise return a copy.

返回:

The circuit with durations converted to dt units.

wy_qcos.common.cmss.gate_operation module

class wy_qcos.common.cmss.gate_operation.GateOperation(name, targets=None, arg_value=None, operation_type=OperationType.SINGLE_QUBIT_OPERATION.value, hermitian=True)

基类：BaseOperation

中间表示类.

validate_params()

Validate gate's params.

Operation type already indicated the number of qubits that gate needed.

decompose()

门对应的分解规则，如无指定规则，则调用默认的分解方法.

分解规则以字典的形式指定，配置在GlobalSetting的decomposition_rule中，其每个item的形式为:

gate_name: #门名称
{
    "param": [str] #形式化的门参数，数量与门实际所需一致，
                    如无参数，该项可不填
    "gates": [based_gates] #指定的分解形式，以based_gates列表表示
}

其中based_gates为一个三元组（name, targets, exps）, name表示门名称，targets为作用比特下标列表(从0开始), exps为参数对应的表达式，以字符串的形式表示，表达式中的操作数可为param中定义的形式化参数以及常量，常量中π可用pi表示

示例:

decomposition_rule = {
    "u3": {
        "params": ["a", "b", "c"],
        "gates": [
            ("rz", [0], ["c"]),
            ("rx", [0], ["pi/2"]),
            ("rz", [0], ["b+pi"]),
            ("rx", [0], ["pi/2"]),
            ("rz", [0], ["a+pi"]),
        ],
    },
    "h": {"gates": [("rx", [0], ["pi/2"])]},
}

decompose_to_1q2q()

default_decompose(): 默认的分解方法.

static with_gate_array(base_array, dtype=None): Return the complex matrix for the gate.

static with_controlled_gate_array(base_array, ctrl_state, num_ctrl_qubits, cached_states=None, dtype=None)

Return the complex matrix.

Description:: If cached_states is not given, then all possible control states are precomputed. If it is given, it should be an iterable of integers, and only these control states will be cached.

to_matrix()

Return a Numpy.ndarray for the gate unitary matrix.

返回:

a matrix array of the gate.

返回类型:

np.ndarray

抛出:

ValueError -- If a Gate subclass does not implement this method
an exception will be raised when this base class method is called. --
