High-quality and field resilient microwave resonators on Ge/SiGe quantum well heterostructures
Luigi Ruggiero, Carlo Ciacca, Pauline Drexler +5
Superconducting resonators integrated with Ge quantum wells (QWs) offer a promising platform for hybrid quantum devices. Yet, in the most common heterostructure architectures, they…
Micromagnet-free operation of electron spin qubits in Si/SiGe vertical double quantum dots
Abhikbrata Sarkar, Daniel Loss
We study a vertical double quantum dot (DQD) in a Si/SiGe/Si double-well heterostructure for full electrical control of electron Loss-DiVincenzo (LD) spin qubits, using…
Indistinguishable photons from a two-photon cascade
Timon L. Baltisberger, Francesco Salusti, Mark R. Hogg +7
Decay of a four-level diamond scheme via a cascade is a potential source of entangled photon pairs. A solid-state implementation is the biexciton cascade in a semiconductor quantum…
Noncooperative Quantum Networks
Yanxuan Shao, Jannik L. Wyss, Don Towsley +1
Existing protocols for quantum communication networks usually assume an initial allocation of quantum entanglement resources, which are then manipulated through local operations an…
On the Cutting Edge: Helical Liquids in Time-Reversal-Invariant Topological Materials
Chen-Hsuan Hsu, Jelena Klinovaja, Daniel Loss
In this perspective, we discuss the unique electronic properties of helical liquids appearing at the boundaries of time-reversal-invariant topological materials and highlight the k…
Deterministic Equations for Feedback Control of Open Quantum Systems III: Full counting statistics for jump-based feedback
Alberto J. B. Rosal, Guilherme Fiusa, Patrick P. Potts +1
In this work, we consider a general feedback protocol based on quantum-jump detections, where the last detected jump channel is stored in a memory and subsequently used to implemen…
Deterministic Equations for Feedback Control of Open Quantum Systems II: Properties of the memory function
Alberto J. B. Rosal, Patrick P. Potts, Gabriel T. Landi
Feedback uses past detection outcomes to dynamically modify a quantum system and is central to quantum control. These outcomes can be stored in a memory, defined as a stochastic fu…
New high-statistics measurement of the Dalitz decay at the Mainz Microtron
S. Prakhov, L. Heijkenskjöld, S. Abt +69
The Dalitz decay has been measured with the highest statistical accuracy obtained so far in the reaction with the A2 tagged-photon facility at the M…
Quantum limit cycles and synchronization from a measurement perspective
Tobias Nadolny, Christoph Bruder
Limit-cycle oscillators are the basic building blocks for synchronization; yet, the notion of a quantum limit cycle has remained unclear. Here, we study quantum limit cycles and sy…
Scattering of the defocusing Calogero--Moser derivative nonlinear Schrödinger equation
Xi Chen
In this paper, we study the long time behavior of solutions to the defocusing Calogero--Moser derivative nonlinear Schrödinger equation (CM-DNLS). Using the Gérard-type explicit fo…
Uncertainties in the production of iron-group nuclides in core-collapse supernovae from Monte Carlo variations of reaction rates
Nobuya Nishimura, Carla Froehlich, Thomas Rauscher
Core-collapse supernovae, occurring at the end of massive star evolution, produce heavy elements, including those in the iron peak. Although the explosion mechanism is not yet full…
Electron-beam-induced Contactless Manipulation of Interlayer Twist in van der Waals Heterostructures
Nicola Curreli, Tero S. Kulmala, Riya Sebait +6
The ability to dynamically control the relative orientation of layers in two dimensional (2D) van der Waals (vdW) heterostructures represents a critical step toward the realization…
Are heuristic switches necessary to control dissipation in modern smoothed particle hydrodynamics ?
Domingo García-Senz, Rubén M. Cabezón
Artificial viscosity is commonly employed in smoothed particle hydrodynamics (SPH) to model dissipation in hydrodynamic simulations. However, its practical implementation today rel…

Noise cross-correlations from single-shot measurements
Juan S. Rojas-Arias, Peter Stano, Yi-Hsien Wu +3
We introduce a novel method that we call Single-Shot Cross-Spectroscopy (SSCS), for extracting the auto- and cross-power spectral densities of dephasing noise of a qubit pair. The…
Family of Unconventional Superconductivities in Crystalline Graphene
Junseok Seo, Armel A. Cotten, Mingchi Xu +17
Unconventional superconductors exhibit multiple broken symmetries and exceed the range of the Bardeen-Cooper-Schrieffer (BCS) theory. For instance, time-reversal symmetry can be br…
Distinguishing Majorana bound states from accidental zero-energy modes with a microwave cavity
Sarath Prem, Olesia Dmytruk, Mircea Trif
Transport measurements of hybrid nanowires often rely on the observation of a zero-bias conductance peak as a hallmark of Majorana bound states (MBSs). However, such signatures can…
