Quantum walk on a square lattice with identical particles
Gonzalo Camacho, Jasmin Meinecke, Janik Wolters
We investigate quantum superposition effects in two-dimensional quantum walks of identical particles with different statistics under particle exchange, starting from various differ…
Analysing quantum systems with randomised measurements
Paweł Cieśliński, Satoya Imai, Jan Dziewior +6
Measurements with randomly chosen settings determine many important properties of quantum states without the need for a shared reference frame or calibration. They naturally emerge…
Valid and efficient entanglement verification with finite copies of a quantum state
Pawel Cieslinski, Jan Dziewior, Lukas Knips +5
Detecting entanglement in multipartite quantum states is an inherently probabilistic process, typically with a few measured samples. The level of confidence in entanglement detecti…
Tracing Information Flow from Open Quantum Systems
Jan Dziewior, Leonardo Ruscio, Lukas Knips +3
Open quantum systems are highly relevant, both for practical applications as well as for fundamental questions about the nature of information and its transfer, encompassing for ex…
Cooperation and dependencies in multipartite systems
Waldemar Klobus, Marek Miller, Mahasweta Pandit +7
We propose an information-theoretic quantifier for the advantage gained from cooperation that captures the degree of dependency between subsystems of a global system. The quantifie…
Multipartite Entanglement Analysis From Random Correlations
Lukas Knips, Jan Dziewior, Waldemar Kłobus +5
Quantum entanglement is usually revealed via a well aligned, carefully chosen set of measurements. Yet, under a number of experimental conditions, for example in communication with…
Measurement-Disturbance Tradeoff Outperforming Optimal Cloning
Lukas Knips, Jan Dziewior, Anna-Lena K. Hashagen +3
One of the characteristic features of quantum mechanics is that every measurement that extracts information about a general quantum system necessarily causes an unavoidable disturb…
Universality of local weak interactions and its application for interferometric alignment
Jan Dziewior, Lukas Knips, Demitry Farfurnik +7
The modification of the effect of interactions of a particle as a function of its pre- and postselected states is analyzed theoretically and experimentally. The universality proper…
An Improved Experiment to Determine the `Past of a Particle' in the Nested Mach-Zehnder Interferometer
Alon Ben-Israel, Lukas Knips, Jan Dziewior +4
We argue that the modification proposed by Li et al. [Chin. Phys. Lett. 32, 050303 (2015)] to the experiment of Danan et al. [Phys. Rev. Lett. 111, 240402 (2013)] does not test the…
Weak value beyond conditional expectation value of the pointer readings
Lev Vaidman, Alon Ben-Israel, Jan Dziewior +6
It is argued that a weak value of an observable is a robust property of a single pre- and post-selected quantum system rather than a statistical property. During an infinitesimal t…
On the experimental verification of quantum complexity in linear optics
Jacques Carolan, Jasmin D. A. Meinecke, Pete Shadbolt +8
The first quantum technologies to solve computational problems that are beyond the capabilities of classical computers are likely to be devices that exploit characteristics inheren…
Quantum walks of correlated photon pairs in two-dimensional waveguide arrays
Konstantinos Poulios, Robert Keil, Daniel Fry +9
We demonstrate quantum walks of correlated photons in a 2D network of directly laser written waveguides coupled in a 'swiss cross' arrangement. The correlated detection events show…
Coherent Time Evolution and Boundary Conditions of Two-Photon Quantum Walks
Jasmin D. A. Meinecke, Konstantinos Poulios, Alberto Politi +6
Multi-photon quantum walks in integrated optics are an attractive controlled quantum system, that can mimic less readily accessible quantum systems and exhibit behavior that cannot…
Simulating quantum statistics with entangled photons: a continuous transition from bosons to fermions
Jonathan C. F. Matthews, Konstantinos Poulios, Jasmin D. A. Meinecke +6
In contrast to classical physics, quantum mechanics divides particles into two classes-bosons and fermions-whose exchange statistics dictate the dynamics of systems at a fundamenta…
String Quantization and the Shuffle Hopf Algebra
Dorothea Bahns, Jasmin D. A. Meinecke
The Poisson algebra of invariants of the Nambu-Goto string, which was first introduced by K. Pohlmeyer in 1982, is described using the Shuffle Hopf algebra. In partic…
