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…
Making the Virtual Real: Measurement-Powered Tunneling Engines
Rafael Sánchez, Alok Nath Singh, Andrew N. Jordan +1
Quantum tunneling allows electrons to be transferred between two regions separated by an energetically forbidden barrier. Performing a position measurement that finds a particle in…
Metrological approach to the emergence of classical objectivity
Anthony Kiely, Diana A. Chisholm, Akram Touil +3
We present a precise characterization of the onset of classicality that combines the formalism of quantum Darwinism with the tools from quantum metrology. We show that the quantum…
Subtleties in the pseudomodes formalism
Wynter Alford, Laetitia P. Bettmann, Gabriel T. Landi
The pseudomode method for open quantum systems, also known as the mesoscopic leads approach, consists in replacing a structured environment by a set of auxiliary "pseudomodes" subj…
Current-based metrology with two-terminal mesoscopic conductors
Shishir Khandelwal, Gabriel T. Landi, Géraldine Haack +1
The traditional approach to quantum parameter estimation focuses on the quantum state, deriving fundamental bounds on precision through the quantum Fisher information. In most expe…
Nonequilibrium steady states in multi-bath quantum collision models
Ronan McElvogue, Andrew K. Mitchell, Gabriel T. Landi +1
Collision models provide a simple and versatile setting to capture the dynamics of open quantum systems. The standard approach to thermalisition in this setting involves an environ…
Extracting filtered signal statistics of continuously measured quantum systems
Anthony Kiely, Gabriel T. Landi
The joint state of a continuously monitored quantum system and the classical filtered measurement record has recently been shown to be described by a quantum Fokker-Planck master e…
Violation of local realism with spatially multimode parametric down-conversion pumped by spatially incoherent light
Cheng Li, Jeremy Upham, Boris Braverman +1
We experimentally demonstrate a violation of local realism with highly spatially multimode polarization-entangled two-photon states produced by spontaneous parametric down-conversi…
Deterministic Equations for Feedback Control of Open Quantum Systems
Alberto J. B. Rosal, Patrick P. Potts, Gabriel T. Landi
Feedback control in open quantum dynamics is crucial for the advancement of various coherent platforms. However, currently only a handful of feedback master equations exist in the…
Probing excited-state dynamics of transmon ionization
Zihao Wang, Benjamin D'Anjou, Philippe Gigon +2
The fidelity and quantum nondemolition character of the dispersive readout in circuit QED are limited by unwanted transitions to highly excited states at specific photon numbers in…
Tree tensor network hierarchical equations of motion based on time-dependent variational principle for efficient open quantum dynamics in structured thermal environments
Xinxian Chen, Ignacio Franco
We introduce an efficient method TTN-HEOM for exactly calculating the open quantum dynamics for driven quantum systems interacting with highly structured bosonic baths by combining…
Field energy and angular momentum in spontaneous emission: A Schrödinger-picture approach
P. R. Berman, A. Kuzmich, P. W Milonni
A Schrödinger-picture approach is used to calculate the field energy and angular momentum radiated by an atom undergoing spontaneous emission. The calculation is carried out using…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
CDJ-Pontryagin Optimal Control for General Continuously Monitored Quantum Systems
Tathagata Karmakar, Andrew N. Jordan
The Chantasri-Dressel-Jordan (CDJ) stochastic path integral formalism (Chantasri et al. 2013 and 2015) characterizes the statistics of the readouts and the most likely conditional…
Scalable low-latency entanglement distribution for distributed quantum computing
Jiapeng Zhao, Yang Xu, Xiyuan Lu +5
Practical distributed quantum computing and error correction require quantum networks with high-qubit-rate, high-fidelity, and low-reconfiguration-latency. Unfortunately, current a…
Capturing an Electron in the Virtual State
Alok Nath Singh, Bibek Bhandari, Rafael Sánchez +1
We address a foundational question in quantum mechanics: Can a particle be directly found in a classically forbidden virtual state? We instantiate this conceptual question by inves…
Revealing the fuel of a quantum continuous measurement-based refrigerator
Cyril Elouard, Sreenath K. Manikandan, Andrew N. Jordan +1
While quantum measurements have been shown to constitute a resource for operating quantum thermal machines, the nature of the energy exchanges involved in the interaction between s…
Full-field mapping of spatially varying polarization entanglement generated from spontaneous parametric down-conversion
Cheng Li, Girish Kulkarni, Isaac Soward +6
Two-photon states generated from spontaneous parametric down-conversion (SPDC) can display entanglement in all degrees of freedom (DoFs) of light, including spatial, temporal, and…
