Universal Bounds for Out-of-Distribution Unitary Learning
Joachim Favre, Armando Angrisani, Zoë Holmes
How much can the action of an unknown unitary dynamics on one family of states reveal about its action elsewhere? We develop a general framework for out-of-distribution quantum dyn…
Dissipation accelerates quantum and classical simulation of open-system dynamics
Armando Angrisani, Ricard Puig, Yanting Teng +1
Simulating open quantum systems reveals how environmental coupling shapes relaxation, excitation transport, and the dynamics of quantum correlations. On quantum hardware, dissipati…
The Complexity of Dynamical Correlators: Operator Shadows and Exponential Learning Separations
Shao-Hen Chiew, Armando Angrisani, Zoe Holmes
Quantum platforms can realize many-body dynamics beyond classical simulation yet complete readout remains intractable: the cost of extracting accessible information scales exponent…
Coherent-State Propagation: A Computational Framework for Simulating Bosonic Quantum Systems
Nikita Guseynov, Zoë Holmes, Armando Angrisani
We introduce coherent-state propagation, a computational framework for simulating bosonic systems. We focus on bosonic circuits composed of displaced linear optics augmented by Ker…
Quantum simulation in the Heisenberg picture via vectorization
Shao-Hen Chiew, Armando Angrisani, Zoë Holmes +1
We present a general framework for simulating quantum systems in the Heisenberg picture on quantum hardware. Based on the vectorization map, our framework fully exploits the mappin…
Thermal State Simulation with Pauli and Majorana Propagation
Manuel S. Rudolph, Armando Angrisani, Andrew Wright +3
We introduce a propagation-based approach to thermal state simulation by adapting Pauli and Majorana propagation to imaginary-time evolution in the Schrödinger picture. Our key obs…
