#量子计算# 内置算法和模型： 该框架提供了一些内置的量子机器学习算法和模型，例如 Quantum Support Vector Machine（QSVM）、Variational Quantum Eigensolver（VQE）和 Quantum Neural Networks（QNN）。这些算法和模型可以用于解决各种问题，如分类、回归和优化等。可扩展性和模块化： Qiskit Machine Learning 的架构...
What should we add? I would like to discuss improving the way bounds are handled and settle/implement such an improvment: For variational algorithms, like VQE, that use an optimizer, while the initial_point (x0) for the minimize can be p...
We investigate the use of the unitary coupled cluster with singles and doubles (UCCSD) Ansatz using VQE within Qiskit and compare results to full configuration interaction (FCI) calculations. Computed ground state energies, electron affinities, ionization potentials, and dipole moments are considered. ...
landscape of challenges, the evolution of quantum algorithms has led to the development of more advanced methods, moving beyond traditional approaches like the Variational Quantum Eigensolver (VQE). This progress paved the way for the creation of the QSCI (Quantum-Selected Configr...

Lastly the chemistryapplicationsmay be used. These are given a chemistry driver and, in the case ofMolecularGroundStateEnergyan optional instance of an AquaMinimumEigensolver, such asVQE. Optional since components such asUCCSDneed certain information that may be unknown at this point. So alternative...
