Quantum digital cooling
2021 · Physical Review A
We introduce a method for digital preparation of ground states of simulated Hamiltonians, inspired by cooling in nature and adapted to leverage the capabilities of digital quantum hardware. The cold bath is simulated by a …

The advantage of quantum control in many-body Hamiltonian learning
2023 · arXiv (Cornell University)
We study the problem of learning the Hamiltonian of a many-body quantum system from experimental data. We show that the rate of learning depends on the amount of control available during the experiment. We consider …

Compilation of product-formula Hamiltonian simulation via reinforcement learning
2023 · arXiv (Cornell University)
Hamiltonian simulation is believed to be one of the first tasks where quantum computers can yield a quantum advantage. One of the most popular methods of Hamiltonian simulation is Trotterization, which makes use of the …
