Exact chiral symmetry with quantum signal processing
Henry Lamm, Alessandro Roggero, Hersh Singh +1
The paper presents a quantum signal processing algorithm that implements the overlap fermion Hamiltonian with controllable error, enabling near‑exact chiral symmetry in quantum sim…
Binary Gauss Stabilizers for Abelian Lattice Gauge Theories
Matteo Turco, Luca Spagnoli, Alessandro Roggero
The paper introduces binary Gauss stabilizers for discrete Abelian lattice gauge theories with Z_N groups (N a power of two), providing an alternative to Gauss operators that can b…
Fault-Tolerant Resource Comparison of Qudit and Qubit Encodings for Diagonal Quadratic Operators
Samuel Godwood, DoÄa Murat KürkçüoÄlu, Gabriel N. Perdue +2
Finite local Hilbert-space truncations arise naturally in quantum simulations of lattice field theories and motivate qudit encodings, but their fault-tolerant advantage over qubit…
Schrödinger-Navier-Stokes Equation for the Quantum Simulation of Navier-Stokes Flows
Luca Cappelli, Sauro Succi, Monica Lacatus +2
The search for quantum-like wave formulations of the Navier-Stokes (Schrödinger-Navier-Stokes, SNS for short) equations describing classical dissipative fluids has met with increa…
Neutrino Flavor Evolution in High Flux Astrophysical Environments
Joseph Carlson, Alessandro Roggero, Duff Neill
We examine neutrino evolution in astrophysical environments where the neutrino flux is very large, including core-collapse supernovae and neutron star mergers. In these environment…
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…
