Universal cooling of quantum systems via randomized measurements
Josias Langbehn, George Mouloudakis, Emma King +5
Designing cooling protocols is believed to require knowledge of the system spectrum. In contrast, cooling in nature occurs whenever the system is coupled to a cold bath. How does n…
Speeding up Quantum Annealing with Engineered Dephasing
Mykolas Sveistrys, Josias Langbehn, Raphaël Menu +3
Building on the insight that engineered noise, specifically, engineered dephasing can enhance the adiabaticity of controlled quantum dynamics, we investigate how a dephasing-genera…
Dilute measurement-induced cooling into many-body ground states
Josias Langbehn, Kyrylo Snizhko, Igor Gornyi +3
Cooling a quantum system to its ground state is important for the characterization of non-trivial interacting systems, and in the context of a variety of quantum information platfo…
Reservoir-engineering shortcuts to adiabaticity
Raphaël Menu, Josias Langbehn, Christiane P. Koch +1
We propose a protocol that achieves fast adiabatic transfer between two orthogonal states of a qubit by coupling with an ancilla. The qubit undergoes Landau-Zener dynamics, whereas…
Topological superconductivity in tripartite superconductor-ferromagnet-semiconductor nanowires
Josias Langbehn, Sergio Acero Gonzalez, Piet W. Brouwer +1
Motivated by recent experiments searching for Majorana zero modes in tripartite semiconductor nanowires with epitaxial superconductor and ferromagnetic-insulator layers, we explore…
Reflection symmetric second-order topological insulators and superconductors
Josias Langbehn, Yang Peng, Luka Trifunovic +2
Second-order topological insulators are crystalline insulators with a gapped bulk and gapped crystalline boundaries, but topologically protected gapless states at the intersection…
