成员函数说明

expval_hamiltonian()

float pyqpanda3.core.core.CPUQVM.expval_hamiltonian	(		self,
		QProg	prog,
			hamiltonian,
		int	shots = ...,
		NoiseModel	noise_model = ... )

expval_hamiltonian(self: core.core.CPUQVM, prog: core.core.QProg, hamiltonian: QPanda3::Hamiltonian, shots: int = 1000, noise_model: core.core.NoiseModel = <core.core.NoiseModel object at 0x7f485423a7b0>) -> float

Calculate the expected value of a given Hamiltonian with respect to a quantum program.

This member function of the CPUQVM class computes the expected value (or expectation value) of a specified Hamiltonian using a quantum program. It allows for the simulation of quantum circuits with optional noise modeling.

参数

prog	The quantum program to be executed.
hamiltonian	The Hamiltonian for which the expected value is to be calculated.
shots	The number of times the quantum program is sampled to estimate the expected value. Defaults to 1000 if not specified.
noise_model	The noise model to be applied during the simulation. Defaults to a default-constructed NoiseModel if not specified.

返回

The expected value of the Hamiltonian as a double.

expval_pauli_operator()

float pyqpanda3.core.core.CPUQVM.expval_pauli_operator	(		self,
		QProg	prog,
			pauli_operator,
		int	shots = ...,
		NoiseModel	noise_model = ... )

expval_pauli_operator(self: core.core.CPUQVM, prog: core.core.QProg, pauli_operator: QPanda3::PauliOperator, shots: int = 1000, noise_model: core.core.NoiseModel = <core.core.NoiseModel object at 0x7f484ebbcff0>) -> float

Calculate the expected value of a given PauliOperator with respect to a quantum program.

This member function of the CPUQVM class computes the expected value (or expectation value) of a specified PauliOperator using a quantum program. It allows for the simulation of quantum circuits with optional noise modeling.

参数

prog	The quantum program to be executed.
pauli_operator	The PauliOperator for which the expected value is to be calculated.
shots	The number of times the quantum program is sampled to estimate the expected value. Defaults to 1000 if not specified.
noise_model	The noise model to be applied during the simulation. Defaults to a default-constructed NoiseModel if not specified.

返回

The expected value of the PauliOperator as a double.

result()

QResult pyqpanda3.core.core.CPUQVM.result

(

self

)

result(self: core.core.CPUQVM) -> core.core.QResult

Get the result of the quantum program execution.

返回

The result of the quantum simulation.

run()

None pyqpanda3.core.core.CPUQVM.run	(		self,
		QProg	prog,
		int	shots,
		NoiseModel	model = ... )

run(self: core.core.CPUQVM, prog: core.core.QProg, shots: int, model: core.core.NoiseModel = <core.core.NoiseModel object at 0x7f484eb891b0>) -> None

Run a quantum program using the CPUQVM simulator.

参数

prog	The quantum program to be executed.
shots	The number of shots (repetitions) for measurement.
model	The noise model to apply (default is NoiseModel()).

返回

None
