Scalable Bell inequalities for qubit graph states and robust self-testing
F. Baccari, R. Augusiak, I. Šupić +2
Bell inequalities constitute a key tool in quantum information theory: they not only allow one to reveal nonlocality in composite quantum systems, but, more importantly, they can b…
Symphony on Strong Field Approximation
Kasra Amini, Jens Biegert, Francesca Calegari +22
This paper has been prepared by the Symphony collaboration (University of Warsaw, Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of the "simpl…
Coherence and asymmetry cannot be broadcast
Matteo Lostaglio, Markus P. Mueller
In the presence of conservation laws, superpositions of eigenstates of the corresponding conserved quantities cannot be generated by quantum dynamics. Thus, any such coherence repr…
Experimental Low-Latency Device-Independent Quantum Randomness
Yanbao Zhang, Lynden K. Shalm, Joshua C. Bienfang +10
Applications of randomness such as private key generation and public randomness beacons require small blocks of certified random bits on demand. Device-independent quantum random n…
Anomalous weak values and contextuality: robustness, tightness, and imaginary parts
Ravi Kunjwal, Matteo Lostaglio, Matthew F. Pusey
Weak values are quantities accessed through quantum experiments involving weak measurements and post-selection. It has been shown that 'anomalous' weak values (those lying beyond t…
Sample complexity of device-independently certified "quantum supremacy"
Dominik Hangleiter, Martin Kliesch, Jens Eisert +1
Results on the hardness of approximate sampling are seen as important stepping stones towards a convincing demonstration of the superior computational power of quantum devices. The…
Distributed Compression of Correlated Classical-Quantum Sources or: The Price of Ignorance
Zahra Baghali Khanian, Andreas Winter
We resume the investigation of the problem of independent local compression of correlated quantum sources, the classical case of which is covered by the celebrated Slepian-Wolf the…
Trends of information backflow in disordered spin chains
Sudipto Singha Roy, Utkarsh Mishra, Debraj Rakshit
We investigate the trends of information backflow associated with the dynamics of a sub-part of a disordered spin-1/2 transverse field Heisenberg chain for different regimes of the…
PennyLane: Automatic differentiation of hybrid quantum-classical computations
Ville Bergholm, Josh Izaac, Maria Schuld +65
PennyLane is a Python 3 software framework for differentiable programming of quantum computers. The library provides a unified architecture for near-term quantum computing devices,…
Bounds on the capacity and power of quantum batteries
Sergi Julia-Farre, Tymoteusz Salamon, Arnau Riera +2
Quantum batteries, composed of quantum cells, are expected to outperform their classical analogs. The origin of such advantages lies in the role of quantum correlations, which may…
Two-dimensional topological quantum walks in the momentum space of structured light
Alessio D'Errico, Filippo Cardano, Maria Maffei +7
Quantum walks are powerful tools for quantum applications and for designing topological systems. Although they are simulated in a variety of platforms, genuine two-dimensional real…
Thermometry in the quantum regime: Recent theoretical progress
Mohammad Mehboudi, Anna Sanpera, Luis A. Correa
Controlling and measuring the temperature in different devices and platforms that operate in the quantum regime is, without any doubt, essential for any potential application. In t…
Decoherence of spin registers revisited
Jan Tuziemski, Aniello Lampo, Maciej Lewenstein +1
We revisit decoherence process of a qubit register interacting with a thermal bosonic bath. We generalize the previous studies by considering not only the register's behavior but a…
Every entangled state provides an advantage in classical communication
Stefan Bäuml, Andreas Winter, Dong Yang
We investigate the use of noisy entanglement as a resource in classical communication via a quantum channel. In particular, we are interested in the question whether for any entang…
Topological quantum optics using atom-like emitter arrays coupled to photonic crystals
Janos Perczel, Johannes Borregaard, Darrick E. Chang +2
We propose a nanophotonic platform for topological quantum optics. Our system is composed of a two-dimensional lattice of non-linear quantum emitters with optical transitions embed…
Conservation of torus-knot angular momentum in high-order harmonic generation
Emilio Pisanty, Laura Rego, Julio San Román +7
High-order harmonic generation stands as a unique nonlinear optical up-conversion process, mediated by a laser-driven electron recollision mechanism, which has been shown to conser…
Linear programs for entanglement and key distribution in the quantum internet
Stefan Bäuml, Koji Azuma, Go Kato +1
Quantum networks will allow to implement communication tasks beyond the reach of their classical counterparts. A pressing and necessary issue for the design of quantum network prot…
Quantifying Superpositions Between Quantum Evolutions
Manabendra Nath Bera
Quantum mechanics allows coherent superposition between different states of matter. This quality is responsible for major non-classical phenomena that occur in quantum systems. Bey…
A versatile construction of Bell inequalities for the multipartite scenario
Florian J. Curchod, Mafalda L. Almeida, Antonio Acín
Local measurements acting on entangled quantum states give rise to a rich correlation structure in the multipartite scenario. We introduce a versatile technique to build families o…
Dynamics of quantum measurements employing two Curie-Weiss apparatuses
Martí Perarnau-Llobet, Theo M. Nieuwenhuizen
Two types of quantum measurements, measuring the spins of an entangled pair and attempting to measure a spin at either of two positions, are analysed dynamically by apparatuses of…
Verifying the output of quantum optimizers with ground-state energy lower bounds
Flavio Baccari, Christian Gogolin, Peter Wittek +1
Solving optimisation problems encoded in the ground state of classical-spin systems is a focus area for quantum computing devices, providing upper bounds to the unknown solution. T…
