Emergent quantum technologies have led to increasing interest in decoherence—the processes that limit the appearance of quantum effects and turn them into classical phenomena. One important cause of decoherence is the interaction of a quantum system with its environment, which ‘entangles’ the two and distributes the quantum coherence over so many degrees of freedom as to render it unobservable. Decoherence theory has been complemented by experiments using matter waves coupled to external… 
Quantum gravitational decoherence of matter waves
One of the biggest unsolved problems in physics is the unification of quantum mechanics and general relativity. The lack of experimental guidance has made the issue extremely evasive, though various
Decoherence of electron waves due to induced charges moving through a nearby resistive material
An experiment in which decoherence, i.e. the transition from quantum to classical behaviour, can be studied in detail was proposed by Anglin and Zurek [1] and has now been realized. An electron beam
Quantum decoherence
Erratum: Coherence in the presence of absorption and heating in a molecule interferometer
TLDR
Evidence that center-of-mass coherence can be maintained even when the internal energy and entropy of the interfering particle are substantially increased by absorption of photons from a standing light wave is provided.
Decoherence of high-ℓ Rydberg wave packets
Quantum revivals in very-high-n (n ~ 300) high-l Rydberg wave packets generated from parent np states are used to examine decoherence induced by the application of 'coloured' noise from a random
The Simplest Double Slit: Interference and Entanglement in Double Photoionization of H2
TLDR
It is shown that a photoelectron and two protons form a minimum particle/slit system and that a single additional electron constitutes a minimum environment and that interference fringes observed in the angular distribution of a single electron are lost through its Coulomb interaction with a second electron.
Quantum interference and imaging using intense laser fields
The interference of matter waves is one of the intriguing features of quantum mechanics that has impressed researchers and laymen since it was first suggested almost a century ago. Nowadays,

Wave–particle duality of C60 molecules
TLDR
The observation of de Broglie wave interference of C60 molecules by diffraction at a material absorption grating is reported, which is the most massive and complex object in which wave behaviour has been observed.
Decoherence of quantum superpositions through coupling to engineered reservoirs
TLDR
Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.
Decoherence, einselection, and the quantum origins of the classical
as quantum engineering. In the past two decades it has become increasingly clear that many (perhaps all) of the symptoms of classicality can be induced in quantum systems by their environments. Thus
Photon scattering from atoms in an atom interferometer: Coherence lost and regained.
TLDR
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.
The emergence of classical properties through interaction with the environment
The dependence of macroscopic systems upon their environment is studied under the assumption that quantum theory is universally valid. In particular scattering of photons and molecules turns out to
Dephasing in electron interference by a ‘which-path’ detector
Wave–particle duality, as manifest in the two-slit experiment, provides perhaps the most vivid illustration of Bohr's complementarity principle: wave-like behaviour (interference) occurs only when
An electronic Mach–Zehnder interferometer
TLDR
This device is the first electronic analogue of the optical Mach–Zehnder interferometer, and opens the way to measuring interference of quasiparticles with fractional charges, and is highly sensitive and exhibits very high visibility.
Collisional decoherence observed in matter wave interferometry.
TLDR
The practical limits of matter wave interferometers at finite gas pressures are explored and the required experimental vacuum conditions for interferometry with even larger objects are estimated.

Concepts for near-field interferometers with large molecules
We study the theory behind a Talbot–Lau interferometer. This consists of three gratings in each other’s Fresnel near field and accepts spatially incoherent illumination. Our formalism gives a clear
