Expressive power of complex-valued restricted Boltzmann machines for solving non-stoquastic Hamiltonians
Chae-Yeun Park, Michael J. Kastoryano
Variational Monte Carlo with neural network quantum states has proven to be a promising avenue for evaluating the ground state energy of spin Hamiltonians. However, despite continu…
Classical restrictions of generic matrix product states are quasi-locally Gibbsian
Yaiza Aragonés-Soria, Johan Åberg, Chae-Yeun Park +1
We show that the norm squared amplitudes with respect to a local orthonormal basis (the classical restriction) of finite quantum systems on one-dimensional lattices can be exponent…
Avoiding local minima in variational quantum eigensolvers with the natural gradient optimizer
David Wierichs, Christian Gogolin, Michael Kastoryano
We compare the BFGS optimizer, ADAM and Natural Gradient Descent (NatGrad) in the context of Variational Quantum Eigensolvers (VQEs). We systematically analyze their performance on…
