Modern day quantum simulators can prepare a wide variety of quantum states but the accurate estimation of observables from tomographic measurement data often poses a challenge. We tackle this problem by developing a quantum state tomography scheme which relies on approximating the probability distribution over the outcomes of an informationally complete measurement in a variational manifold represented by a convolutional neural network. We show an excellent representability of prototypical… 

Optimizing Design Choices for Neural Quantum States


Efficient quantum state tomography with mode-assisted training

Apply mode-assisted training that provides global information via the modes of the NN distribution to quantum state tomography using restricted Boltzmann machines and improves the quality of reconstructed quantum states by orders of magnitude.



Reconstructing quantum states with generative models

The key insight is to reduce state tomography to an unsupervised learning problem of the statistics of an informationally complete quantum measurement, which constitutes a modern machine learning approach to the validation of complex quantum devices.

Quantum Entanglement in Deep Learning Architectures.

The results show that contemporary deep learning architectures, in the form of deep convolutional and recurrent networks, can efficiently represent highly entangled quantum systems and can support volume-law entanglement scaling, polynomially more efficiently than presently employed RBMs.

Quantum state tomography via compressed sensing.

These methods are specialized for quantum states that are fairly pure, and they offer a significant performance improvement on large quantum systems, and are able to reconstruct an unknown density matrix of dimension d and rank r using O(rdlog²d) measurement settings, compared to standard methods that require d² settings.

Scaling of Neural‐Network Quantum States for Time Evolution

The variational power of the restricted Boltzmann machine quantum states and different shallow and deep neural autoregressive quantum states to simulate the global quench dynamics of a non‐integrable quantum Ising chain is benchmarked.

Deep autoregressive models for the efficient variational simulation of many-body quantum systems

This work proposes a specialized neural- network architecture that supports efficient and exact sampling, completely circumventing the need for Markov-chain sampling, and demonstrates the ability to obtain accurate results on larger system sizes than those currently accessible to neural-network quantum states.

Quantum Computing in the NISQ era and beyond

Noisy Intermediate-Scale Quantum (NISQ) technology will be available in the near future, and the 100-qubit quantum computer will not change the world right away - but it should be regarded as a significant step toward the more powerful quantum technologies of the future.

Iterative maximum-likelihood reconstruction in quantum homodyne tomography

I propose an iterative expectation maximization algorithm for reconstructing the density matrix of an optical ensemble from a set of balanced homodyne measurements. The algorithm applies directly to

Efficient quantum state tomography.

Two tomography schemes that scale much more favourably than direct tomography with system size are presented, one of them requires unitary operations on a constant number of subsystems, whereas the other requires only local measurements together with more elaborate post-processing.

Investigating reconstruction of quantum state distributions with neural networks

It is discovered that the Shannon entropy of QSD is suitable to evaluate the quality of reconstruction, and can be utilized to guide the research of other quantum information problems.
