mindquantum.engine

mindquantum.engine#

Circuit engine module.

class mindquantum.engine.BasicQubit(qubit_id, circuit=None)#

A quantum qubit.

Parameters:

  • qubit_id (int) – The id of this quantum qubit.

  • circuit (Circuit) – The quantum circuit that this qubit belongs to. Default: None.

property circuit#

Get the quantum circuit that this qubit belongs to.

class mindquantum.engine.CircuitEngine#

A simple circuit engine that allows you to generate quantum circuit as projectq style.

allocate_qubit()#

Allocate a quantum qubit.

allocate_qureg(n)#

Allocate a quantum register.

Parameters:

n (int) – Number of quantum qubits.

property circuit#

Get the quantum circuit that construct by this engin.

static generator(n_qubits, *args, **kwds)#

Quantum circuit register.

Parameters:

n_qubits (int) – qubit number of quantum circuit.

Examples

>>> import mindquantum.core.gates as G
>>> from mindquantum.engine import circuit_generator
>>> @circuit_generator(2,prefix='p')
... def ansatz(qubits, prefix):
...     G.X | (qubits[0], qubits[1])
...     G.RX(prefix+'_0') | qubits[1]
>>> print(ansatz)
