Does Quantum Mechanics Clash with the Equivalence Principle – and Does it Matter? [PDF]

, 2010
With an eye on developing a quantum theory of gravity, many physicists have recently searched for quantum challenges to the equivalence principle of general relativity.

Experimental statistical signature of many-body quantum interference [PDF]

Nature Photonics, 2018
Multi-particle interference is an essential ingredient for fundamental quantum mechanics phenomena and for quantum information processing to provide a computational advantage, as recently emphasized by boson sampling experiments.

Controlling quantum interference in phase space with amplitude

Scientific Reports, 2017
We experimentally show a quantum interference in phase space by interrogating photon number probabilities (n = 2, 3, and 4) of a displaced squeezed state, which is generated by an optical parametric amplifier and whose displacement is controlled by ...

Nonmagnetic single-molecule spin-filter based on quantum interference

Nature Communications, 2019
Key spin transport phenomena, including magnetoresistance and spin transfer torque, cannot be activated without spin-polarized currents, in which one electron spin is dominant.

Non-local quantum interference of deterministically separated photons

Results in Optics
Quantum entanglement enables a wide range of fundamental studies and practical applications in quantum optics, computing, and communication. In this work, we investigate two-photon interference using position-momentum entangled photons generated via Type-

Double-slit photoelectron interference in strong-field ionization of the neon dimer [PDF]

Nature Communications, 2018
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept.

Theory of Fano effect in cavity quantum electrodynamics

Physical Review Research, 2021
We propose a Markovian quantum master equation that can describe the Fano effect directly, by assuming a standard cavity quantum electrodynamics system. The framework allows us to generalize the Fano formula, applicable over the weak- and strong-coupling

Quantum experiments and graphs II: Quantum interference, computation, and state generation [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Graph theory can be used to model and explain different phenomena from physics. In this paper, we show that one can interpret quantum experiments composed of linear optics and probabilistic sources with graph theory.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
