covariant -parametrized maps
Andrei B. Klimov, Ulrich Seyfarth, Hubert de Guise +1
We propose a practical recipe to compute the -parametrized maps for systems with symmetry using a connection between the and symbols through the action…
Thermalization induced by quantum scattering
Samuel L. Jacob, Massimiliano Esposito, Juan M. R. Parrondo +1
We use quantum scattering theory to study a fixed quantum system Y subject to collisions with massive particles X described by wave-packets. We derive the scattering map for system…
Defence against adversarial attacks using classical and quantum-enhanced Boltzmann machines
Aidan Kehoe, Peter Wittek, Yanbo Xue +1
We provide a robust defence to adversarial attacks on discriminative algorithms. Neural networks are naturally vulnerable to small, tailored perturbations in the input data that le…
Crosstalk Suppression for Fault-tolerant Quantum Error Correction with Trapped Ions
Pedro Parrado-Rodríguez, Ciarán Ryan-Anderson, Alejandro Bermudez +1
Physical qubits in experimental quantum information processors are inevitably exposed to different sources of noise and imperfections, which lead to errors that typically accumulat…
Relaxation times do not capture logical qubit dynamics
Amit Kumar Pal, Philipp Schindler, Alexander Erhard +5
Quantum error correction procedures have the potential to enable faithful operation of large-scale quantum computers. They protect information from environmental decoherence by sto…
Non-Abelian Quantum Transport and Thermosqueezing Effects
Gonzalo Manzano, Juan M. R. Parrondo, Gabriel T. Landi
Modern quantum experiments provide examples of transport with non-commuting quantities, offering a tool to understand the interplay between thermal and quantum effects. Here we set…
Locality of temperature and correlations in the presence of non-zero-temperature phase transitions
Senaida Hernández Santana, Andras Molnar, Christian Gogolin +2
While temperature is well understood as an intensive quantity in standard thermodynamics, it is less clear whether the same holds in the presence of strong correlations, especially…
Violation of Bell quantum probability inequalities with classical fields
Laura Ares, Alfredo Luis
Violations of Bell inequalities in classical optics have been demonstrated in terms of field mean intensities and correlations, however, the quantum meaning of violations point to…
Efficient and robust certification of genuine multipartite entanglement in noisy quantum error correction circuits
Andrea Rodriguez-Blanco, Alejandro Bermudez, Markus Müller +1
Ensuring the correct functioning of quantum error correction (QEC) circuits is crucial to achieve fault tolerance in realistic quantum processors subjected to noise. The first chec…
Extremal quantum states
Aaron Z. Goldberg, Andrei B. Klimov, Markus Grassl +2
The striking differences between quantum and classical systems predicate disruptive quantum technologies. We peruse quantumness from a variety of viewpoints, concentrating on phase…
Achieving the ultimate quantum timing resolution
Vahid Ansari, Benjamin Brecht, Jano Gil-López +5
Accurate time-delay measurement is at the core of many modern technologies. Here, we present a temporal-mode demultiplexing scheme that achieves the ultimate quantum precision for…
Detector self-tomography
Raúl Cónsul, Alfredo Luis
We present an intuitive model of detector self-tomography. Two identical realisations of the detector are illuminated by an entangled state that connects the joint statistics in a…
Fundamental quantum limits in ellipsometry
L. Rudnicki, L. L. Sanchez-Soto, G. Leuchs +1
We establish the ultimate limits that quantum theory imposes on the accuracy attainable in optical ellipsometry. We show that the standard quantum limit, as usual reached when the…
Graph approach to quantum teleportation dynamics
E. Honrubia, A. S. Sanz
Quantum teleportation plays a key role in modern quantum technologies. Thus, it is of much interest to generate alternative approaches or representations aimed at allowing us a bet…
Compressively certifying quantum measurements
I. Gianani, Y. S. Teo, V. Cimini +4
We introduce a reliable compressive procedure to uniquely characterize any given low-rank quantum measurement using a minimal set of probe states that is based solely on data colle…
Circuit implementation of bucket brigade qRAM for quantum state preparation
Pablo Antonio Moreno Casares
In this short review I aim to explain how we can construct a circuit implementation of the bucketbrigade qRAM first proposed in [1]. Used with classical data, this qRAM model can b…
Universal compressive characterization of quantum dynamics
Yosep Kim, Yong Siah Teo, Daekun Ahn +6
Recent quantum technologies utilize complex multidimensional processes that govern the dynamics of quantum systems. We develop an adaptive diagonal-element-probing compression tech…
Quantum Zermelo problem for general energy resource bounds
J. M. Bofill, A. S. Sanz, G. Albareda +2
A solution to the quantum Zermelo problem for control Hamiltonians with general energy resource bounds is provided. Interestingly, the energy resource of the control Hamiltonian an…
Observed quantum dynamics: classical dynamics and lack of Zeno effect
Julián López, Laura Ares, Alfredo Luis
We examine a case study where classical evolution emerges when observing a quantum evolution. By using a single-mode quantum Kerr evolution interrupted by measurement of the double…
Optimizing the spatial spread of a quantum walk
Gonzalo Martín-Vázquez, Javier Rodríguez-Laguna
We devise a protocol to build 1D time-dependent quantum walks in 1D maximizing the spatial spread throughout the procedure. We allow only one of the physical parameters of the coin…
Genuine multipartite nonlocality is intrinsic to quantum networks
Patricia Contreras-Tejada, Carlos Palazuelos, Julio I. de Vicente
Quantum entanglement and nonlocality are inextricably linked. However, while entanglement is necessary for nonlocality, it is not always sufficient in the standard Bell scenario. W…
Efficient description of many-body systems with Matrix Product Density Operators
Jiri Guth Jarkovsky, Andras Molnar, Norbert Schuch +1
Matrix Product States form the basis of powerful simulation methods for ground state problems in one dimension. Their power stems from the fact that they faithfully approximate sta…
Anomalous Thermalization in Quantum Collective Models
Armando Relaño
We show that apparently thermalized states still store relevant amounts of information about their past, information that can be tracked by experiments involving nonequilibrium pro…
Inaccessible entanglement in symmetry protected topological phases
Caroline de Groot, David T. Stephen, Andras Molnar +1
We study the entanglement structure of symmetry-protected topological (SPT) phases from an operational point of view by considering entanglement distillation in the presence of sym…
