Duality relation between coherence and path information in the presence of quantum memory
The wave-particle duality demonstrates a competition relation between wave
and particle behavior for a particle going through an interferometer. This
duality can be formulated as an inequality, which upper bounds the sum of
interference visibility and path information. However, if the particle is
entangled with a quantum memory, then the bound may decrease. Here, we find the
duality relation between coherence and path information for a particle going
through a multipath interferometer in the presence of a quantum memory,
offering an upper bound on the duality relation which is directly connected
with the amount of entanglement between the particle and the quantum memory.Comment: 6 pages, 1 figure, comments are welcom

Simplifying Low-Light Image Enhancement Networks with Relative Loss Functions
Image enhancement is a common technique used to mitigate issues such as
severe noise, low brightness, low contrast, and color deviation in low-light
images. However, providing an optimal high-light image as a reference for
low-light image enhancement tasks is impossible, which makes the learning
process more difficult than other image processing tasks. As a result, although
several low-light image enhancement methods have been proposed, most of them
are either too complex or insufficient in addressing all the issues in
low-light images. In this paper, to make the learning easier in low-light image
enhancement, we introduce FLW-Net (Fast and LightWeight Network) and two
relative loss functions. Specifically, we first recognize the challenges of the
need for a large receptive field to obtain global contrast and the lack of an
absolute reference, which limits the simplification of network structures in
this task. Then, we propose an efficient global feature information extraction
component and two loss functions based on relative information to overcome
these challenges. Finally, we conducted comparative experiments to demonstrate
the effectiveness of the proposed method, and the results confirm that the
proposed method can significantly reduce the complexity of supervised low-light
image enhancement networks while improving processing effect. The code is
