Machine learning design of a trapped-ion quantum spin simulator
Yi Hong Teoh, Marina Drygala, Roger G. Melko +1
Trapped ions have emerged as one of the highest quality platforms for the quantum simulation of interacting spin models of interest to various fields of physics. In such simulators…
The learnability scaling of quantum states: restricted Boltzmann machines
Dan Sehayek, Anna Golubeva, Michael S. Albergo +3
Generative modeling with machine learning has provided a new perspective on the data-driven task of reconstructing quantum states from a set of qubit measurements. As increasingly…
Wavefunction positivization via automatic differentiation
Giacomo Torlai, Juan Carrasquilla, Matthew T. Fishman +2
We introduce a procedure to systematically search for a local unitary transformation that maps a wavefunction with a non-trivial sign structure into a positive-real form. The trans…
Machine learning quantum states in the NISQ era
Giacomo Torlai, Roger G. Melko
We review the development of generative modeling techniques in machine learning for the purpose of reconstructing real, noisy, many-qubit quantum states. Motivated by its interpret…
Universal divergence of the Renyi entropy of a thinly sliced torus at the Ising fixed point
Bohdan Kulchytskyy, Lauren E. Hayward Sierens, Roger G. Melko
The entanglement entropy of a quantum critical system can provide new universal numbers that depend on the geometry of the entangling bipartition. We calculate a universal number c…
Integrating Neural Networks with a Quantum Simulator for State Reconstruction
Giacomo Torlai, Brian Timar, Evert P. L. van Nieuwenburg +9
We demonstrate quantum many-body state reconstruction from experimental data generated by a programmable quantum simulator, by means of a neural network model incorporating known e…
Making Trotters Sprint: A Variational Imaginary Time Ansatz for Quantum Many-body Systems
Matthew J. S. Beach, Roger G. Melko, Tarun Grover +1
We introduce a variational wavefunction for many-body ground states that involves imaginary time evolution with two different Hamiltonians in an alternating fashion with variable t…
