Light-matter coupling via quantum pathways for spontaneous symmetry breaking in van der Waals antiferromagnetic semiconductors

Nature Communications
Light-matter interaction simultaneously alters both the original material and incident light. Light not only reveals material details but also activates coupling mechanisms.

Quantum coherence and interference of a single moiré exciton in nano-fabricated twisted monolayer semiconductor heterobilayers

Nature Communications
The moiré potential serves as a periodic quantum confinement for optically generated excitons, creating spatially ordered zero-dimensional quantum systems. However, a broad emission spectrum resulting from inhomogeneity among moiré potentials hinders the

Observation of genuine three-photon interference

, 2017
Multiparticle quantum interference is critical for our understanding and exploitation of quantum information, and for fundamental tests of quantum mechanics.

Near-unity quantum interference of transverse spatial modes in an ultra-compact inverse-designed photonic device [PDF]

APL Photonics
Transverse spatial modes as a degree of freedom is an untapped resource for scaling up integrated photonic quantum computing. To be practically useful for improving scalability, reliable and high-visibility quantum interference between transverse spatial

Can photon be considered as its trajectory self-detector (self-collapse as spontaneous superposition breaking)

, 2022
In this work we theoretically considered variations of remarkable experiments of single photon interference ( at beam splitter, at diaphragm with two slits, etc., especially recent experiment of such kind realized by V. Jacques, E.

Coherence Properties of Molecular Single Photons for Quantum Networks

Physical Review X, 2018
Quantum mechanics implies that a single photon can be in the superposition of two distant spatial modes and enable nonlocal interferences. The most vivid example is the two-photon coalescence on a 50∶50 beam splitter, known as Hong-Ou-Mandel interference.

Quantum erasure with causally disconnected choice

, 2013
The counterintuitive features of quantum physics challenge many common-sense assumptions. In an interferometric quantum eraser experiment, one can actively choose whether or not to erase which-path information, a particle feature, of one quantum system ...

Entanglement of an Atom and Its Spontaneous Emission Fields via Spontaneously Generated Coherence [PDF]

Journal of Sciences, Islamic Republic of Iran, 2011
The entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. The effect of spontaneously generated coherence (SGC) on entanglement between the atom and its spontaneous emission fields is then discussed.

Experimental generalized quantum suppression law in Sylvester interferometers

New Journal of Physics, 2018
Photonic interference is a key quantum resource for optical quantum computation, and in particular for so-called boson sampling devices. In interferometers with certain symmetries, genuine multiphoton quantum interference effectively suppresses certain ...
