Spin-liquid-based topological qubits
Kai Klocke, Yue Liu, Gábor B. Halász +1
Topological quantum computation relies on control of non-Abelian anyons for inherently fault-tolerant storage and processing of quantum information. By now, blueprints for topologi…
Entanglement dynamics in monitored Kitaev circuits: loop models, symmetry classification, and quantum Lifshitz scaling
Kai Klocke, Daniel Simm, Guo-Yi Zhu +2
Quantum circuits offer a versatile platform for simulating digital quantum dynamics and uncovering novel states of non-equilibrium quantum matter. One principal example are measure…
Power-law entanglement and Hilbert space fragmentation in non-reciprocal quantum circuits
Kai Klocke, Joel E. Moore, Michael Buchhold
Quantum circuits utilizing measurement to evolve a quantum wave function offer a new and rich playground to engineer unconventional entanglement dynamics. Here we introduce a hybri…
Spontaneous localization at a potential saddle point from edge state reconstruction in a quantum Hall point contact
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
Quantum point contacts (QPCs) are an essential component in mesoscopic devices. Here, we study the transmission of quantum Hall edge modes through a gate-defined QPC in monolayer g…
Majorana Loop Models for Measurement-Only Quantum Circuits
Kai Klocke, Michael Buchhold
Projective measurements in random quantum circuits lead to a rich breadth of entanglement phases and extend the realm of non-unitary quantum dynamics. Here we explore the connectio…
Nanoscale electrostatic control in ultra clean van der Waals heterostructures by local anodic oxidation of graphite gates
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
In an all-van der Waals heterostructure, the active layer, gate dielectrics and gate electrodes are assembled from two-dimensional crystals that have a low density of atomic defect…
Topological order and entanglement dynamics in the measurement-only XZZX quantum code
Kai Klocke, Michael Buchhold
We examine the dynamics of a -dimensional measurement-only circuit defined by the stabilizers of the [[5,1,3]] quantum error correcting code interrupted by single-qubit Paul…
Localization crossover and subdiffusive transport in a classical facilitated network model of a disordered, interacting quantum spin chain
Kai Klocke, Christopher David White, Michael Buchhold
We consider the random-field Heisenberg model, a paradigmatic model for many-body localization (MBL), and add a Markovian dephasing bath coupled to the Anderson orbitals of the mod…
Thermal anyon interferometry in phonon-coupled Kitaev spin liquids
Kai Klocke, Joel E. Moore, Jason Alicea +1
Recent theoretical studies inspired by experiments on the Kitaev magnet -RuCl highlight the nontrivial impact of phonons on the thermal Hall conductivity of chiral topologic…
Time-domain anyon interferometry in Kitaev honeycomb spin liquids and beyond
Kai Klocke, David Aasen, Roger S. K. Mong +2
Motivated by recent experiments on the Kitaev honeycomb magnet , we introduce time-domain probes of the edge and quasiparticle content of non-Abelian spin liquids.…
Hydrodynamic stabilization of self-organized criticality in a driven Rydberg gas
K. Klocke, T. M. Wintermantel, G. Lochead +2
Signatures of self-organized criticality (SOC) have recently been observed in an ultracold atomic gas under continuous laser excitation to strongly-interacting Rydberg states [S. H…
Controlling excitation avalanches in driven Rydberg gases
Kai Klocke, Michael Buchhold
Recent experiments with strongly interacting, driven Rydberg ensembles have introduced a promising setup for the study of self-organized criticality (SOC) in cold atom systems. Bas…
