Unitary Designs from Doped Matchgate Circuits
Fabian Ballar Trigueros, Zheng-Hang Sun, Xhek Turkeshi +2
Matchgate circuits realize free-fermion dynamics: they are efficiently classically simulable, yet cannot on their own generate the generic randomness required for universal computa…
Dynamics of defects and interfaces for interacting quantum hard disks
Fabian Ballar Trigueros, Vighnesh Dattatraya Naik, Markus Heyl
Defects and interfaces are essential to understand the properties of matter. However, studying their dynamics in the quantum regime remains a challenge in particular concerning the…
Quantum Circuits as a Dynamical Resource to Learn Nonequilibrium Long-Range Order
Fabian Ballar Trigueros, Markus Heyl
Equilibrium statistical ensembles impose stringent constraints on phases of quantum matter. For example, the Mermin-Wagner theorem prohibits long-range order in low-dimensional sys…
Probing prethermal nonergodicity through measurement outcomes of monitored quantum dynamics
Zheng-Hang Sun, Fabian Ballar Trigueros, Qicheng Tang +1
Projective measurements are a key element in quantum physics and enable rich phenomena in monitored quantum dynamics. Here, we show that the measurement outcomes, recorded during m…
Simplicity of mean-field theories in neural quantum states
Fabian Ballar Trigueros, Tiago Mendes-Santos, Markus Heyl
The utilization of artificial neural networks for representing quantum many-body wave functions has garnered significant attention, with enormous recent progress for both ground st…
