One-shot manipulation of entanglement for quantum channels
Ho-Joon Kim, Soojoon Lee, Ludovico Lami +1
We show that the dynamic resource theory of quantum entanglement can be formulated using the superchannel theory. In this formulation, we identify the separable channels and the cl…
Enhanced force sensitivity and entanglement in periodically driven optomechanics
F. Cosco, J. S. Pedernales, M. B. Plenio
Squeezing is a resource that enables precision enhancements in quantum metrology and can be used as a basis for the generation of entanglement by linear optics. While strong squeez…
Excitation dynamics in chain-mapped environments
Dario Tamascelli
The chain mapping of structured environments is a most powerful tool for the simulation of open quantum system dynamics. Once the environmental bosonic or fermionic degrees of free…
Validity of Born-Markov master equations for single and two-qubit systems
Vasilii Vadimov, Jani Tuorila, Tuure Orell +4
The urgent need for reliable simulation tools to match the extreme accuracy needed to control tailored quantum devices highlights the importance of understanding open quantum syste…
Fundamental limitations to key distillation from Gaussian states with Gaussian operations
Ludovico Lami, Ladislav Mišta, Gerardo Adesso
We establish fundamental upper bounds on the amount of secret key that can be extracted from quantum Gaussian states by using only local Gaussian operations, local classical proces…
Asymptotic state transformations of continuous variable resources
Giovanni Ferrari, Ludovico Lami, Thomas Theurer +1
We study asymptotic state transformations in continuous variable quantum resource theories. In particular, we prove that monotones displaying lower semicontinuity and strong supera…
Framework for resource quantification in infinite-dimensional general probabilistic theories
Ludovico Lami, Bartosz Regula, Ryuji Takagi +1
Resource theories provide a general framework for the characterization of properties of physical systems in quantum mechanics and beyond. Here, we introduce methods for the quantif…
Operational quantification of continuous-variable quantum resources
Bartosz Regula, Ludovico Lami, Giovanni Ferrari +1
The diverse range of resources which underlie the utility of quantum states in practical tasks motivates the development of universally applicable methods to measure and compare re…
Precise Spectroscopy of High-Frequency Oscillating Fields with a Single-Qubit Sensor
Yaoming Chu, Pengcheng Yang, Musang Gong +5
Precise spectroscopy of oscillating fields plays significant roles in many fields. Here, we propose an experimentally feasible scheme to measure the frequency of a fast-oscillating…
Parallel selective nuclear spin addressing for fast high-fidelity quantum gates
Benedikt Tratzmiller, Jan F. Haase, Zhenyu Wang +1
Due to their long coherence times, nuclear spins have gained considerable attention as physical qubits. Two-qubit gates between nuclear spins of distinct resonance frequencies can…
Efficient construction of tensor-network representations of many-body Gaussian states
Alexander Nüßeler, Ish Dhand, Susana F. Huelga +1
We present a procedure to construct tensor-network representations of many-body Gaussian states efficiently and with a controllable error. These states include the ground and therm…
Towards simulating 2D effects in lattice gauge theories on a quantum computer
Danny Paulson, Luca Dellantonio, Jan F. Haase +8
Gauge theories are the most successful theories for describing nature at its fundamental level, but obtaining analytical or numerical solutions often remains a challenge. We propos…
Generalized figure of merit for qubit readout
B. D'Anjou
Many promising approaches to fault-tolerant quantum computation require repeated quantum nondemolition (QND) readout of binary observables such as quantum bits (qubits). A commonly…
Atomic Raman scattering: Third-order diffraction in a double geometry
Sabrina Hartmann, Jens Jenewein, Sven Abend +2
In a retroreflective scheme atomic Raman diffraction adopts some of the properties of Bragg diffraction due to additional couplings to off-resonant momenta. As a consequence, doubl…
Boson sampling with random numbers of photons
Vincenzo Tamma, Simon Laibacher
Multiphoton interference is at the very heart of quantum foundations and applications in quantum sensing and information processing. In particular, boson sampling experiments have…

Johannes Seiler, Thomas Strohm, Wolfgang Schleich
We analyze the information an attacker can obtain on the numbers generated by a user by measurements on a subsystem of a system consisting of two entangled two-level systems. The a…
Interplay between geometric and dynamic phases in a single spin system
A. A. Wood, K. Streltsov, R. M. Goldblatt +4
We use a combination of microwave fields and free precession to drive the spin of a nitrogen-vacancy (NV) center in diamond on different trajectories on the Bloch sphere, and inves…
