Kernel Embedding for Operator-Valued Measures and Its Application to Quantum Tomography
Philipp Nikolas Mayer, Ho Yun
This paper introduces the Quantum Covariance Embedding, which embeds Positive Operator-Valued Measures into a tensor product of a Reproducing Kernel Hilbert Space and the quantum s…
Spectral Shrinkage of Gaussian Entropic Optimal Transport
Ho Yun
We present a functional calculus treatment of Entropic Optimal Transport (EOT) between Gaussian measures on separable Hilbert spaces, providing a unified framework that handles inf…
Computerized Tomography and Reproducing Kernels
Ho Yun, Victor M. Panaretos
The X-ray transform is one of the most fundamental integral operators in image processing and reconstruction. In this article, we revisit the formalism of the X-ray transform by co…
Redheffer: Trig to Quantum Error Bounds
Ho Yun
In the existing literature, the Redheffer inequality is typically proven using mathematical induction. In this short paper, we present a straightforward proof of this inequality by…
