Classical shadow tomography for continuous variables quantum systems
Simon Becker, Nilanjana Datta, Ludovico Lami +1
In this article we develop a continuous variable (CV) shadow tomography scheme with wide ranging applications in quantum optics. Our work is motivated by the increasing experimenta…
Active spin lattice hyperpolarization: Application to hexagonal boron nitride color centers
F. T. Tabesh, M. Fani, J. S. Pedernales +2
The active driving of the electron spin of a color center is known as a method for the hyperpolarization of the surrounding nuclear spin bath and to initialize a system with large…
Nature and origin of the operators entering the master equation of an open quantum system
Giovanni Spaventa, Paola Verrucchi
By exploiting the peculiarities of a recently introduced formalism for describing open quantum systems (the Parametric Representation with Environmental Coherent States) we derive…
Unraveling-paired dynamical maps can recover the input of quantum channels
Brecht Donvil, Paolo Muratore-Ginanneschi
We explore algebraic and dynamical consequences of unraveling general time-local master equations. We show that the "influence martingale", the paramount ingredient of a recently d…
Efficient Information Retrieval for Sensing via Continuous Measurement
Dayou Yang, Susana F. Huelga, Martin B. Plenio
Continuous monitoring of driven-dissipative quantum optical systems is a crucial element in the implementation of quantum metrology, providing essential strategies for achieving hi…
Overcoming entropic limitations on asymptotic state transformations through probabilistic protocols
Bartosz Regula, Ludovico Lami, Mark M. Wilde
The quantum relative entropy is known to play a key role in determining the asymptotic convertibility of quantum states in general resource-theoretic settings, often constituting t…
Non-perturbative treatment of open-system multi-time expectation values in Gaussian bosonic environments
A. Smirne, D. Tamascelli, J. Lim +2
We determine the conditions for the equivalence between the multi-time expectation values of a general finite-dimensional open quantum system when interacting with, respectively, a…
Rapid determination of single substitutional nitrogen N concentration in diamond from UV-Vis spectroscopy
T. Luo, L. Lindner, R. Blinder +6
Single substitutional nitrogen atoms N are the prerequisite to create nitrogen-vacancy (NV) centers in diamonds. They serve as the electron donors to create the desired NV$^-…
Quantum LOSR networks cannot generate graph states with high fidelity
Yi-Xuan Wang, Zhen-Peng Xu, Otfried Gühne
Quantum networks lead to novel notions of locality and correlations and an important problem concerns the question of which quantum states can be experimentally prepared with a giv…
Fingerprint and universal Markovian closure of structured bosonic environments
Alexander Nüßeler, Dario Tamascelli, Andrea Smirne +3
We exploit the properties of chain mapping transformations of bosonic environments to identify a finite collection of modes able to capture the characteristic features, or fingerpr…
Robust Two-Qubit Gates Using Pulsed Dynamical Decoupling
Patrick Barthel, Patrick H. Huber, Jorge Casanova +5
We present the experimental implementation of a two-qubit phase gate, using a radio frequency (RF) controlled trapped-ion quantum processor. The RF-driven gate is generated by a pu…
Spin operator, Bell nonlocality and Tsirelson bound in quantum-gravity induced minimal-length quantum mechanics
Pasquale Bosso, Luciano Petruzziello, Fabian Wagner +1
Different approaches to quantum gravity converge in predicting the existence of a minimal scale of length. This raises the fundamental question as to whether and how an intrinsic l…
Experimental demonstration of topological bounds in quantum metrology
Min Yu, Xiangbei Li, Yaoming Chu +6
Quantum metrology is deeply connected to quantum geometry, through the fundamental notion of quantum Fisher information. Inspired by advances in topological matter, it was recently…
Geometric interpretation of the CHSH inequality of nonmaximally entangled states
Johannes Seiler, Thomas Strohm, Wolfgang P. Schleich
We show that for pure and mixed states the problem of maximizing the correlation measure in the CHSH inequality reduces to maximizing the perimeter of a parallelogram enclosed by a…

Patrik Schach, Alexander Friedrich, Jason R. Williams +2
We examine the prospects of utilizing matter-wave Fabry-Pérot interferometers for enhanced inertial sensing applications. Our study explores such tunneling-based sensors for the me…
Exact solution for the quantum and private capacities of bosonic dephasing channels
Ludovico Lami, Mark M. Wilde
The capacities of noisy quantum channels capture the ultimate rates of information transmission across quantum communication lines, and the quantum capacity plays a key role in det…
On a gap in the proof of the generalised quantum Stein's lemma and its consequences for the reversibility of quantum resources
Mario Berta, Fernando G. S. L. Brandão, Gilad Gour +4
We show that the proof of the generalised quantum Stein's lemma [Brandão & Plenio, Commun. Math. Phys. 295, 791 (2010)] is not correct due to a gap in the argument leading to Lemma…
A Quantum Optical Microphone in the Audio Band
Raphael Nold, Charles Babin, Joel Schmidt +12
The ability to perform high-precision optical measurements is paramount to science and engineering. Laser interferometry enables interaction-free sensing with a precision ultimatel…
Quantum Optical Communication in the presence of strong attenuation noise
Francesco Anna Mele, Ludovico Lami, Vittorio Giovannetti
Is quantum communication possible over an optical fibre with transmissivity ? The answer is well known to be negative if the environment with which the incoming signal…
Restoring quantum communication efficiency over high loss optical fibres
Francesco Anna Mele, Ludovico Lami, Vittorio Giovannetti
In the absence of quantum repeaters, quantum communication proved to be nearly impossible across optical fibres longer than due to the drop of transmissivity…
