Proof-of-Principle Implementation of Quantum Key Distribution in an Indefinite Causal Order
Yann Valibouse, Martí Cladera-Rosselló, Michael Antesberger +6
In quantum physics, the order in which different operations occur can be placed in superposition. The resulting processes have an indefinite causal order, which is of fundamental i…
Time-Delocalized Local Measurements in an Indefinite Causal Order
Yann Valibouse, Martí Cladera-Rosselló, Michael Antesberger +3
Processes with indefinite causal order (ICO), such as the quantum switch, are an emerging resource for quantum tasks and a fundamental test bed for studies of temporal correlations…
Toward an Experimental Device-Independent Verification of Indefinite Causal Order
Carla M. D. Richter, Michael Antesberger, Huan Cao +2
In classical physics, events follow a definite causal order: the past influences the future, but not the reverse. Quantum theory, however, permits superpositions of causal orders -…
Experimental Quantum State Certification by Actively Sampling Photonic Entangled States
Michael Antesberger, Mariana M. E. Schmid, Huan Cao +3
Entangled quantum states are essential ingredients for many quantum technologies, but they must be validated before they are used. As a full characterization is prohibitively resou…
Distribution of Telecom Entangled Photons through a 7.7 km Antiresonant Hollow-Core Fiber
Michael Antesberger, Carla M. D. Richter, Francesco Poletti +6
State of the art classical and quantum communication rely on standard optical fibers with solid cores to transmit light over long distances. However, recent advances have led to th…
Higher-order Process Matrix Tomography of a passively-stable Quantum SWITCH
Michael Antesberger, Marco Túlio Quintino, Philip Walther +1
The field of indefinite causal order (ICO) has seen a recent surge in interest. Much of this research has focused on the quantum SWITCH, wherein multiple parties act in a superposi…
Feedback-cooling the fundamental torsional mechanical mode of a tapered optical fiber to 30 mK
Felix Tebbenjohanns, Jihao Jia, Michael Antesberger +5
Tapered optical fibers (TOFs) are used in many areas of physics and optical technologies ranging from coupling light into nanophotonic components to optical sensing and amplificati…
Experimental superposition of time directions
Teodor Strömberg, Peter Schiansky, Marco Túlio Quintino +5
In the macroscopic world, time is intrinsically asymmetric, flowing in a specific direction, from past to future. However, the same is not necessarily true for quantum systems, as…
Enhanced Photonic Maxwell's Demon with Correlated Baths
Guilherme L. Zanin, Michael Antesberger, Maxime J. Jacquet +3
Maxwell's Demon is at the heart of the interrelation between quantum information processing and thermodynamics. In this thought experiment, a demon generates a temperature gradient…
Experimental quantum memristor
Michele Spagnolo, Joshua Morris, Simone Piacentini +6
Quantum computer technology harnesses the features of quantum physics for revolutionizing information processing and computing. As such, quantum computers use physical quantum gate…
