Abstract

The invention provides a quantum Gibbs state generation method and device and electronic equipment, and belongs to the technical field of quanta. The method comprises the following steps: acquiring atarget Hamiltonian amount; determining a target loss function according to the polynomial expansion of the free energy function corresponding to the target Hamiltonian quantity; determining a target vector corresponding to a parameter vector in a preset parameterized quantum circuit according to the value of the target loss function; substituting the target vector into a preset parameterized quantum circuit to determine a target quantum circuit; acting the target quantum circuit on the initial states of the first type of system and the second type of system, obtaining the target quantum stateof the target quantum circuit on the first type of system, wherein the dimension of the first type of system is the same as the dimension of the target Hamiltonian quantity; and determining a Gibbs state corresponding to the target Hamiltonian quantity according to the target quantum state. Therefore, by means of the quantum Gibbs state generation method, the quantum Gibbs state is efficiently andaccurately generated.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of quantum technology, and proposes a quantum Gibbs state generation method, device and electronic equipment. Background technique [0002] In the field of quantum machine learning and quantum computing, the generation of specific quantum states is an extremely important problem. In particular, especially the generation of Gibbs state is a necessary step to realize many quantum algorithms. [0003] In related technologies, the method of calculating the free energy of quantum states by using amplitude estimation and quantum signal processing, and then generating the Gibbs state, because both amplitude estimation and quantum signal processing require a large number of qubits to realize, it cannot be implemented in the present Some quantum computers run. Therefore, there is an urgent need for a quantum Gibbs state generation method that can run in existing qu...
