Bang-bang protocol for nondispersive qubit readout
Nina del Ser, Yinan Chen, Jacob Steiner +1
Fast, precise, and quantum-non-demolition (QND) readout of superconducting qubits is a fundamental component of high-fidelity quantum sensing and computation. Conventional approach…
Prethermal cooling with many-body quantum quenches
Jacob F. Steiner, Mohammad Hafezi, Stefan Kehrein +1
Many-body quantum quenches are typically associated with heating. In this work, we show that quantum quenches that perform positive work on the system can still lead to effective c…
Active quantum matter from monitored pure-state dynamics
Jacob F. Steiner, Felix von Oppen, Reinhold Egger
Quantum many-body systems coupled to out-of-equilibrium reservoirs can behave as active matter and exhibit signs of flocking. However, the resulting steady states are highly mixed…
Dynamics of Josephson junctions beyond the tunneling limit
Jacob F. Steiner, Larissa Melischek, Felix von Oppen
The dynamics of the superconducting phase difference across a Josephson junction can be described within the resistively and capacitively shunted Josephson junction (RCSJ) model. M…
Multi-band fractional Thouless pumps
Marius Jürgensen, Jacob Steiner, Gil Refael +1
Quantization of particle transport lies at the heart of topological physics. In Thouless pumps - dimensionally reduced versions of the integer quantum Hall effect - quantization is…
