Quantum superposition lies at the heart of quantum mechanics and gives rise to many of its paradoxes. Superposition of de Broglie matter waves has been observed for massive particles such as electrons, atoms and dimers, small van der Waals clusters, and neutrons. But matter wave interferometry with larger objects has remained experimentally challenging, despite the development of powerful atom interferometric techniques for experiments in fundamental quantum mechanics, metrology and lithography… Expand

Quantum interference experiments with large molecules
Wave–particle duality is frequently the first topic students encounter in elementary quantum physics. Although this phenomenon has been demonstrated with photons, electrons, neutrons, and atoms, the… Expand
Quantum interference of large organic molecules
TLDR
It is shown that even complex systems, with more than 1,000 internal degrees of freedom, can be prepared in quantum states that are sufficiently well isolated from their environment to avoid decoherence and to show almost perfect coherence. Expand
Foundation experiments in quantum atom optics with ultracold metastable helium
The field of atom optics has progressed rapidly over the past 20 years since the realisation of Bose-Einstein condensation, such that the wave behaviour of atomic gases is now routinely demonstrated.… Expand
Particle diffraction studied using quantum trajectories
Diffraction and interference of matter waves are key phenomena in quantum mechanics. Here we present some results on particle diffraction in a wide variety of situations, ranging from simple slit… Expand
Engineering the quantum transport of atomic wavefunctions over macroscopic distances
How far can you stretch an atomic wavefunction? An experiment demonstrates that the wavefunction of an ensemble of ultracold atoms trapped in an optical lattice can be reversibly expanded and shrunk… Expand
Matter-wave interference of particles selected from a molecular library with masses exceeding 10,000 amu.
TLDR
It is demonstrated how synthetic chemistry allows us to prepare libraries of fluorous porphyrins which can be tailored to exhibit high mass, good thermal stability and relatively low polarizability, which allows for successful superposition experiments with selected species from these molecular libraries in a quantum interferometer, which utilizes the diffraction of matter-waves at an optical phase grating.

First observation of antimatter wave interference
In 1924 Louis de Broglie introduced the concept of wave-particle duality: the Planck constant $h$ relates the momentum $p$ of a massive particle to its de Broglie wavelength $\lambda=h/p$. The… Expand
Quantum Interference and Superposition
Apart from technological applications, interference experiments with massive particles in ample range of masses (electrons, neutrons, atoms, small clusters, organic molecules, or even Bose-Einstein… Expand
A Kapitza–Dirac–Talbot–Lau interferometer for highly polarizable molecules
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons1, neutrons2, atoms3, Bose-condensed ensembles4, cold clusters5 and hot… Expand
Decoherence of matter waves by thermal emission of radiation
TLDR
Good quantitative agreement is found between the experimental observations and microscopic decoherence theory of matter wave interferometer experiments in which C70 molecules lose their quantum behaviour by thermal emission of radiation. Expand

While in the last decade atom interferometry[1] has become a rapidly expanding field, coherent de Broglie optics with large molecules has still remained completely unexplored. We propose that… Expand

Experiments are discussed here in which this entanglement results from the elastic scattering of a photon from an atom initially in a state with extended spatial coherence inside an atom interferometer. Expand

TLDR
Wave interference fringes are revealed by their selective destruction and ac-modulated laser light passes through the interferometer, is scattered by atoms at one velocity, and destroys, and thereby reveals via the ac modulation, the associated high-frequency fringe contribution. Expand
