Predicting Noise in a Trapped-ion Quantum Simulation of a Lattice Gauge Theory
Hassan Ugail
A recent trapped-ion experiment realised a lattice gauge theory in which the internal states of the ions carry the gauge field and their vibrations carry bosonic matter. In that ex…

A Coherence Law for Trainability in Noisy Equivariant Quantum Neural Networks
Hassan Ugail, Newton Howard
Symmetry provides a quantum neural network structure, but on its own it does not keep the network trainable once noise is present. We ask which physical quantity decides whether th…
