Macroscopic Hyperpolarization Enhanced with Quantum Optimal Control
Alastair Marshall, Thomas Reisser, Phila Rembold +13
Hyperpolarization of nuclear spins enhances nuclear magnetic resonance signals, which play a key role for imaging and spectroscopy in the natural and life sciences. This signal amp…
Creation of nitrogen-vacancy centers in chemical vapor deposition diamond for sensing applications
T. Luo, L. Lindner, J. Langer +12
The nitrogen-vacancy (NV) center in diamond is a promising quantum system for magnetometry applications exhibiting optical readout of minute energy shifts in its spin sub-levels. K…
Long-Range Non-Equilibrium Coherent Tunneling Induced by Fractional Vibronic Resonances
R. Kevin Kessing, Pei-Yun Yang, Salvatore R. Manmana +1
We study the influence of a linear energy bias on a non-equilibrium excitation on a chain of molecules coupled to local phonons (a tilted Holstein model) using both a random-walk r…
On the Significance of Interferometric Revivals for the Fundamental Description of Gravity
Kirill Streltsov, Julen S. Pedernales, Martin B. Plenio
We show that an interaction between a harmonic oscillator and a two-level test mass (TLTM) mediated by an LOCC channel produces a signature that in [D. Carney et al., PRX Quantum 2…
Approximating Invertible Maps by Recovery Channels: Optimality and an Application to Non-Markovian Dynamics
Lea Lautenbacher, Fernando de Melo, Nadja K. Bernardes
We investigate the problem of reversing quantum dynamics, specifically via optimal Petz recovery maps. We focus on typical decoherence channels, such as dephasing, depolarizing and…
No second law of entanglement manipulation after all
Ludovico Lami, Bartosz Regula
Many fruitful analogies have emerged between the theories of quantum entanglement and thermodynamics, motivating the pursuit of an axiomatic description of entanglement akin to the…
Qubit-based momentum measurement of a particle
Bernd Konrad, Fabio Di Pumpo, Matthias Freyberger
An early approach to include pointers representing measurement devices into quantum mechanics was given by von Neumann. Based on this idea, we model such pointers by qubits and cou…
Adaptive estimation of quantum observables
Ariel Shlosberg, Andrew J. Jena, Priyanka Mukhopadhyay +3
The accurate estimation of quantum observables is a critical task in science. With progress on the hardware, measuring a quantum system will become increasingly demanding, particul…
Detection of Molecular Transitions with Nitrogen-Vacancy Centers and Electron-Spin Labels
C. Munuera-Javaloy, R. Puebla, B. D'Anjou +2
We present a protocol that detects molecular conformational changes with two nitroxide electron-spin labels and a nitrogen-vacancy (NV) center in diamond. More specifically, we dem…
Thermometry of Gaussian quantum systems using Gaussian measurements
Marina F. B. Cenni, Ludovico Lami, Antonio Acin +1
We study the problem of estimating the temperature of Gaussian systems with feasible measurements, namely Gaussian and photo-detection-like measurements. For Gaussian measurements,…
Universal quantum computation with optical four-component cat qubits
Daiqin Su, Ish Dhand, Timothy C. Ralph
We propose a teleportation-based scheme to implement a universal set of quantum gates with a four-component cat code, assisted by appropriate entangled resource states and photon n…
Entanglement and superposition are equivalent concepts in any physical theory
Guillaume Aubrun, Ludovico Lami, Carlos Palazuelos +1
We prove that any two general probabilistic theories (GPTs) are entangleable, in the sense that their composite exhibits either entangled states or entangled measurements, if and o…
Entanglement resonance in the asymmetric quantum Rabi model
Yu-Qing Shi, Lei Cong, Hans-Peter Eckle
We investigate the entanglement features in the interacting system of a quantized optical field and a two-level system which is statically driven, known as the asymmetric quantum R…

Eldad Bettelheim, Aditya Banerjee, Martin B. Plenio +1
The statistical mechanics characterization of a finite subsystem embedded in an infinite system is a fundamental question of quantum physics. Nevertheless, a full closed form { for…

Quantum-enhanced computing methods are promising candidates to solve currently intractable problems. We consider here a variational quantum eigensolver (VQE), that delegates costly…
Criticality-Enhanced Quantum Sensing via Continuous Measurement
Theodoros Ilias, Dayou Yang, Susana F. Huelga +1
Present protocols of criticality-enhanced sensing with open quantum sensors assume direct measurement of the sensor and omit the radiation quanta emitted to the environment, thereb…
Robust Macroscopic Matter-Wave Interferometry with Solids
Julen S. Pedernales, Martin B. Plenio
Matter-wave interferometry with solids is highly susceptible to minute fluctuations of environmental fields, including gravitational effects from distant sources. Hence, experiment…
