Empirical Sample Complexity of Neural Network Mixed State Reconstruction

1 code implementation4 Jul 2023 Haimeng Zhao, Giuseppe Carleo, Filippo Vicentini

Quantum state reconstruction using Neural Quantum States has been proposed as a viable tool to reduce quantum shot complexity in practical applications, and its advantage over competing techniques has been shown in numerical experiments focusing mainly on the noiseless case.

Learning ground states of gapped quantum Hamiltonians with Kernel Methods

no code implementations15 Mar 2023 Clemens Giuliani, Filippo Vicentini, Riccardo Rossi, Giuseppe Carleo

Neural network approaches to approximate the ground state of quantum hamiltonians require the numerical solution of a highly nonlinear optimization problem.

Positive-definite parametrization of mixed quantum states with deep neural networks

no code implementations27 Jun 2022 Filippo Vicentini, Riccardo Rossi, Giuseppe Carleo

We introduce the Gram-Hadamard Density Operator (GHDO), a new deep neural-network architecture that can encode positive semi-definite density operators of exponential rank with polynomial resources.

From Tensor Network Quantum States to Tensorial Recurrent Neural Networks

1 code implementation24 Jun 2022 Dian Wu, Riccardo Rossi, Filippo Vicentini, Giuseppe Carleo

We show that any matrix product state (MPS) can be exactly represented by a recurrent neural network (RNN) with a linear memory update.

Variational Monte Carlo

An efficient quantum algorithm for the time evolution of parameterized circuits

2 code implementations12 Jan 2021 Stefano Barison, Filippo Vicentini, Giuseppe Carleo

Our approach is efficient in the sense that it exhibits an optimal linear scaling with the total number of variational parameters.
