Exact chiral symmetry with quantum signal processing
Henry Lamm, Alessandro Roggero, Hersh Singh +1
We give a quantum signal processing (QSP) algorithm for the overlap fermion Hamiltonian which preserves the Ginsparg-Wilson relation up to a controllable error . Quantum simul…
Binary Gauss Stabilizers for Abelian Lattice Gauge Theories
Matteo Turco, Luca Spagnoli, Alessandro Roggero
Gauge theories and quantum error-correcting codes share the same underlying structure: both use constraints to identify a specific subspace of the full Hilbert space. In quantum er…
Qudit stabiliser codes for lattice gauge theories with matter
Luca Spagnoli, Alessandro Roggero, Nathan Wiebe
In this work we extend the connection between Quantum Error Correction (QEC) and Lattice Gauge Theories (LGTs) by showing that a gauge theory with prime dimension $N…
Collective Neutrino Oscillations in Three Flavors on Qubit and Qutrit Processors
Luca Spagnoli, Noah Goss, Alessandro Roggero +9
Collective neutrino flavor oscillations are of primary importance in understanding the dynamic evolution of core-collapse supernovae and subsequent terrestrial detection, but also…
