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…
Detection of collective modes in unconventional superconductors using tunneling spectroscopy
Patrick A. Lee, Jacob F. Steiner
We propose using tunneling spectroscopy with a superconducting electrode to probe the collective modes of unconventional superconductors. The modes are predicted to appear as peaks…
Diode effects in current-biased Josephson junctions
Jacob F. Steiner, Larissa Melischek, Martina Trahms +2
Current-biased Josephson junctions exhibit hysteretic transitions between dissipative and superconducting states as characterized by switching and retrapping currents. Here, we dev…
Diode effect in Josephson junctions with a single magnetic atom
Martina Trahms, Larissa Melischek, Jacob F. Steiner +8
Current flow in electronic devices can be asymmetric with bias direction, a phenomenon underlying the utility of diodes and known as non-reciprocal charge transport. The promise of…
High-temperature Josephson diode
Sanat Ghosh, Vilas Patil, Amit Basu +8
Symmetry plays a critical role in determining various properties of a material. Semiconducting p-n junction diode exemplifies the engineered skew electronic response and is at the…
Quantum Yu-Shiba-Rusinov dimers
Harald Schmid, Jacob F. Steiner, Katharina J. Franke +1
Magnetic adatoms on a superconducting substrate undergo a quantum phase transition as their exchange coupling to the conduction electrons increases. For quantum spins, this transit…
Surface photogalvanic effect in Weyl semimetals
J. F. Steiner, A. V. Andreev, M. Breitkreiz
The photogalvanic effect -- a rectified current induced by light irradiation -- requires the intrinsic symmetry of the medium to be sufficiently low, which strongly limits candidat…
Quantum spins and hybridization in artificially-constructed chains of magnetic adatoms on a superconductor
Eva Liebhaber, Lisa M. Rütten, Gaël Reecht +5
Magnetic adatom chains on surfaces constitute fascinating quantum spin systems. Superconducting substrates suppress interactions with bulk electronic excitations but couple the ada…
Quantum magnetism and topological superconductivity in Yu-Shiba-Rusinov chains
Jacob F. Steiner, Christophe Mora, Katharina J. Franke +1
Chains of magnetic adatoms on superconductors have been discussed as promising systems for realizing Majorana end states. Here, we show that dilute Yu-Shiba-Rusinov (YSR) chains ar…
Readout of Majorana Qubits
Jacob F. Steiner, Felix von Oppen
Schemes for topological quantum computation with Majorana bound states rely heavily on the ability to measure products of Majorana operators projectively. Here, we employ Markovian…
Anomalous Hall Effect in type-I Weyl metals
J. F. Steiner, A. V. Andreev, D. A. Pesin
We study the ac anomalous Hall conductivity of a Weyl semimetal with broken time-reversal symmetry. Even in the absence of free carriers these materials exhibit a "univ…
