Bridging Quantum and Semi-Classical Thermodynamics in Cavity QED
Marcelo Janovitch, Sander Stammbach, Matteo Brunelli +1
In cavity quantum electrodynamics (QED), photons leaving the cavity can be irreversibly lost or reused as a power source. This dichotomy is reflected in two different thermodynamic…
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…
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…
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…

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…
Path Integral Approach to Input-Output Theory
Aaron Daniel, Matteo Brunelli, Aashish A. Clerk +1
Input-output theory is a well-known tool in quantum optics and ubiquitous in the description of quantum systems probed by light. Owing to the generality of the setup it describes,…
Accelerating the drive towards energy-efficient generative AI with quantum computing algorithms
Frederik F. Flöther, Jan Mikolon, Maria Longobardi
Research and usage of artificial intelligence, particularly generative and large language models, have rapidly progressed over the last years. This has, however, given rise to issu…
Gradient Scalability and Taylor Surrogation of Quantum Cost Landscapes
Sabri Meyer, Francesco Scala, Francesco Tacchino +1
Variational Quantum Algorithms are promising candidates for near-term quantum computing, yet they face scalability challenges due to barren plateaus, where gradients vanish exponen…

Spin-qubit readout analysis based on a hidden Markov model
Maria Spethmann, Peter Stano, Daniel Loss
Across most qubit platforms, the readout fidelities do not keep up with the gate fidelities, and new ways to increase the readout fidelities are searched for. For semiconductor spi…
