Translation symmetry restoration in integrable systems: the noninteracting case
Molly Gibbins, Adam Gammon-Smith, Bruno Bertini
The study of symmetry restoration has recently emerged as a fruitful means to extract high-level information on the relaxation of quantum many-body systems. However, while the rest…
Quantum trajectory simulation of two-dimensional non-equilibrium steady states with a trapped ion quantum processor
Anna Dalmasso, Arash Jafarizadeh, Julian Boesl +8
Digital quantum computers offer a promising route for studying complex many-body systems that are otherwise inaccessible by their classical counterparts. Capabilities including mid…
Disentangling strategies and entanglement transitions in unitary circuit games with matchgates
Raúl Morral-Yepes, Marc Langer, Adam Gammon-Smith +2
In unitary circuit games, two competing parties, an "entangler" and a "disentangler", can induce an entanglement phase transition in a quantum many-body system. The transition occu…
Simulating Topological Order on Quantum Processors
Adam Gammon-Smith, Michael Knap, Frank Pollmann
It is an ongoing quest to realize topologically ordered quantum states on different platforms including condensed matter systems, quantum simulators and digital quantum processors.…
Scalable simulation of non-equilibrium quantum dynamics via classically optimised unitary circuits
Luke Causer, Felix Jung, Asimpunya Mitra +2
The advent of near-term digital quantum computers could offer us an exciting opportunity to investigate quantum many-body phenomena beyond that of classical computing. To make the…
Quench dynamics in lattices above one dimension: the free fermionic case
Molly Gibbins, Arash Jafarizadeh, Adam Gammon-Smith +1
We begin a systematic investigation of quench dynamics in higher-dimensional lattice systems considering the case of non-interacting fermions with conserved particle number. We pre…
A recipe for local simulation of strongly-correlated fermionic matter on quantum computers: the 2D Fermi-Hubbard model
Arash Jafarizadeh, Frank Pollmann, Adam Gammon-Smith
The simulation of quantum many-body systems, relevant for quantum chemistry and condensed matter physics, is one of the most promising applications of near-term quantum computers b…
Phases of Interacting Fibonacci Anyons on a Ladder at Half-Filling
Nico Kirchner, Roderich Moessner, Frank Pollmann +1
Two-dimensional many-body quantum systems can exhibit topological order and support collective excitations with anyonic statistics different from the usual fermionic or bosonic one…
Topological Superconductivity in Altermagnetic Heterostructures on a Honeycomb Lattice
George McArdle, Brian Kiraly, Peter Wadley +1
Altermagnet-superconductor heterostructures have been shown, in principle, to provide a route towards realising topological superconductivity, and therefore host topologically prot…
Matchgate circuit representation of fermionic Gaussian states: optimal preparation, approximation, and classical simulation
Marc Langer, Raúl Morral-Yepes, Adam Gammon-Smith +2
Fermionic Gaussian states (FGSs) and the associated matchgate circuits play a central role in quantum information theory and condensed matter physics. Despite being possibly highly…
Visualizing Dynamics of Charges and Strings in (2+1)D Lattice Gauge Theories
Tyler A. Cochran, Bernhard Jobst, Eliott Rosenberg +189
Lattice gauge theories (LGTs) can be employed to understand a wide range of phenomena, from elementary particle scattering in high-energy physics to effective descriptions of many-…
