A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]

Kramers-protected hardware-efficient error correction with Andreev spin qubits

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Haoran Lu, Isidora Araya Day, Anton R. Akhmerov, Bernard van Heck, Valla Fatemi | Summary: We propose an architecture for bit flip error correction of Andreev spins that is protected by Kramers’ degeneracy. Specifically, we show that a coupling network of linear inductors results in a […]

A two-dimensional 10-qubit array in germanium with robust and localised qubit control

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Valentin John, Cécile X. Yu, Barnaby van Straaten, Esteban A. Rodríguez-Mena, Mauricio Rodríguez | Summary: Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for textit{in situ} electric fast and high-fidelity qubit gates. However, the interaction also […]

Scattering theory of higher order topological phases

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: R. Johanna Zijderveld, Isidora Araya Day, Anton R. Akhmerov, , | Summary: The surface states of intrinsic higher order topological phases are protected by the spatial symmetries of a finite sample. This property makes the existing scattering theory of topological invariants inapplicable because the scattering geometry […]
