Probing quantum mechanics using nanoparticle Schrödinger cats
Sebastian Pedalino, Bruno E. Ramírez-Galindo, Richard Ferstl +3
The quantum superposition principle is a cornerstone of physics and at the heart of many quantum technologies. Yet, it is still often regarded counterintuitive because we do not ob…
Experimental challenges for high-mass matter-wave interference with nanoparticles
Sebastian Pedalino, Bruno Ramírez Galindo, Tomas de Sousa +4
We discuss recent advances towards matter-wave interference experiments with free beams of metallic and dielectric nanoparticles. They require a brilliant source, an efficient dete…
Nanoscale magnetism probed in a matter-wave interferometer
Yaakov Y. Fein, Sebastian Pedalino, Armin Shayeghi +3
We explore a wide range of fundamental magnetic phenomena by measuring the dephasing of matter-wave interference fringes upon application of a variable magnetic gradient. The versa…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
Experimental decoherence in molecule interferometry
Markus Arndt, Stefan Gerlich, Klaus Hornberger
Complex molecules are intriguing objects at the interface between quantum and classical phenomena. Compared to the electrons, neutrons, or atoms studied in earlier matter-wave expe…
Measurement of a microwave field amplitude beyond the standard quantum limit
M. Penasa, S. Gerlich, T. Rybarczyk +6
We report a quantum measurement beyond the standard quantum limit (SQL) for the amplitude of a small displacement acting on a cavity field. This measurement uses as resource an ent…
Past quantum state analysis of the photon number evolution in a cavity
Théo Rybarczyk, Stefan Gerlich, Bruno Peaudecerf +8
A quantum system can be monitored through repeated interactions with meters, followed by their detection. The state of the system at time t is thus conditioned on the information o…
Quantum interference distinguishes between constitutional isomers
Jens Tüxen, Stefan Gerlich, Sandra Eibenberger +2
Matter waves, as introduced by de Broglie in 1923, are a fundamental quantum phenomenon, describing the delocalized center of mass motion of massive bodies and we show here their s…
Influence of conformational molecular dynamics on matter wave interferometry
Michael Gring, Stefan Gerlich, Sandra Eibenberger +9
We investigate the influence of thermally activated internal molecular dynamics on the phase shifts of matter waves inside a molecule interferometer. While de Broglie physics gener…
Matter-wave interference with particles selected from a molecular library with masses exceeding 10000 amu
Sandra Eibenberger, Stefan Gerlich, Markus Arndt +2
The quantum superposition principle, a key distinction between quantum physics and classical mechanics, is often perceived as a philosophical challenge to our concepts of reality,…
Colloquium: Quantum interference of clusters and molecules
Klaus Hornberger, Stefan Gerlich, Philipp Haslinger +2
We review recent progress and future prospects of matter wave interferometry with complex organic molecules and inorganic clusters. Three variants of a near-field interference effe…
Theory and experimental verification of Kapitza-Dirac-Talbot-Lau interferometry
Klaus Hornberger, Stefan Gerlich, Hendrik Ulbricht +5
Kapitza-Dirac-Talbot-Lau interferometry (KDTLI) has recently been established for demonstrating the quantum wave nature of large molecules. A phase space treatment permits us to de…
A Kapitza-Dirac-Talbot-Lau interferometer for highly polarizable molecules
Stefan Gerlich, Lucia Hackermueller, Klaus Hornberger +8
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clus…
Optical polarizabilities of large molecules measured in near-field interferometry
Lucia Hackermueller, Klaus Hornberger, Stefan Gerlich +3
We discuss a novel application of matter wave interferometry to characterize the scalar optical polarizability of molecules at 532 nm. The interferometer presented here consists of…
