Interference of photons from independent hot atoms
JaromÃr Mika, Stuti Joshi, Lukáš Lachman +2
The coherence of light from independent ensembles of elementary atomic emitters plays a paramount role in diverse areas of modern optics. We demonstrate the interference of photons…
Qubit-parity interference despite unknown interaction phases
Kratveer Singh, Kimin Park, VojtÄch Å varc +5
Quantum interference between interacting systems is fundamental to basic science and quantum technology, but it typically requires precise control of the interaction phases of lase…
Sub-Planck structure quantification in non-Gaussian probability densities
Darren W. Moore, VojtÄch Å varc, Kratveer Singh +5
Sub-Planck structures in non-Gaussian probability densities of phase space variables are pervasive in bosonic quantum systems. They are almost universally present if the bosonic sy…
Quantum non-Gaussian coherences of an oscillating atom
A. Kovalenko, L. Lachman, T. Pham +4
Quantum coherence between energy eigenstates of harmonic oscillators is essential for quantum physics. Even the most elementary binary superpositions of the ground and the higher e…
