Engineering the speedup of quantum tunneling in Josephson systems via dissipation
Dominik Maile, Joachim Ankerhold, Sabine Andergassen +2
We theoretically investigate the escape rate occurring via quantum tunneling in a system affected by tailored dissipation. Specifically, we study the environmental assisted quantum…
Tailored Error Mitigation for Single-Qubit Magnetometry
Miriam Resch, Dennis Herb, Mirko Rossini +2
Quantum sensing is an emerging field with the potential to outperform classical methods in both precision and spatial resolution. However, the sensitivity of the underlying quantum…
Performance of quantum registers in diamond in the presence of spin impurities
Dominik Maile, Joachim Ankerhold
The Nitrogen Vacancy Center in diamond coupled to addressable surrounding nuclear spins forms a versatile building block for future quantum technologies. While previous activities…
Exponential speedup of incoherent tunneling via dissipation
Dominik Maile, Sabine Andergassen, Wolfgang Belzig +1
We study the escape rate of a particle in a metastable potential in presence of a dissipative bath coupled to the momentum of the particle. Using the semiclassical bounce technique…
Single Qubit Error Mitigation by Simulating Non-Markovian Dynamics
Mirko Rossini, Dominik Maile, Joachim Ankerhold +1
Quantum simulation is a powerful tool to study the properties of quantum systems. The dynamics of open quantum systems are often described by Completely Positive (CP) maps, for whi…
Quantum phase transition with dissipative frustration
Dominik Maile, Sabine Andergassen, Wolfgang Belzig +1
We study the quantum phase transition of the one-dimensional phase model in the presence of dissipative frustration, provided by an interaction of the system with the environment t…
Effects of a dissipative coupling to the momentum of a particle in a double well potential
Dominik Maile, Sabine Andergassen, Gianluca Rastelli
Double well potentials offer the possibility of coherent state preparation and therefore constitute important building blocks in the analysis of quantum information and quantum eng…
Anomalous Dissipation in Current Biased Josephson Systems
Johannes Hauff, Niklas Gaiser, Joachim Ankerhold +1
The paper theoretically studies how embedding a current‑biased Josephson junction in a resistor‑capacitor circuit creates anomalous dissipation that dramatically alters phase‑diffu…
