Computing with many encoded logical qubits beyond break-even
Shival Dasu, Matthew DeCross, Andrew Y. Guo +42
High-rate quantum error correcting (QEC) codes encode many logical qubits in a given number of physical qubits, making them promising candidates for quantum computation. Implementi…
Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
Superconducting pairing correlations on a trapped-ion quantum computer
Etienne Granet, Sheng-Hsuan Lin, Kevin Hémery +31
The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivat…
Flux-induced midgap states between strain-engineered flat bands
Dung Xuan Nguyen, Jake Arkinstall, Henning Schomerus
Half-integer quantized flux vortices appear in honeycomb lattices when the signs of an odd number of couplings around a plaquette are inverted. We show that states trapped at these…
Experimental Realization of Multiple Topological Edge States in a One-Dimensional Photonic Lattice
Zhifeng Zhang, Mohammad Teimourpour, Jake Arkinstall +5
Topological photonic systems offer light transport that is robust against defects and disorder, promising a new generation of chip-scale photonic devices and facilitating energy-ef…
Topological tight-binding models from non-trivial square roots
J. Arkinstall, M. H. Teimourpour, L. Feng +2
We describe a versatile mechanism that provides tight-binding models with an enriched, topologically nontrivial bandstructure. The mechanism is algebraic in nature, and leads to ti…
Universal sign-control of coupling in tight-binding lattices
Robert Keil, Charles Poli, Matthias Heinrich +4
We present a method of locally inverting the sign of the coupling term in tight-binding systems, by means of inserting a judiciously designed ancillary site and eigenmode matching…
Degeneracy doubling and sublattice polarization in strain-induced pseudo-Landau levels
Charles Poli, Jake Arkinstall, Henning Schomerus
The degeneracy and spatial support of pseudo-Landau levels (pLLs) in strained honeycomb lattices systematically depends on the geometry -- for instance, in hexagonal and rectangula…
