Controlled Fusion Frame in Tensor Product of Hilbert Spaces [PDF]

Mathematica Pannonica
In this paper, we study controlled fusion frame in tensor product of Hilbert spaces and discuss some of its properties. We describe the resolution of the identity operator on a tensor product of Hilbert spaces using the theory of controlled fusion frame.

Regression in tensor product spaces by the method of sieves. [PDF]

Electronic Journal of Statistics, 2022
Estimation of a conditional mean (linking a set of features to an outcome of interest) is a fundamental statistical task. While there is an appeal to flexible nonparametric procedures, effective estimation in many classical nonparametric function spaces,

Tensor Product of 2-Frames in 2-Hilbert Spaces

, 2016
2-frames in 2-Hilbert spaces are studied and some results on it are presented. The tensor product of 2-frames in 2-Hilbert spaces is introduced. It is shown that the tensor product of two 2-frames is a 2-frame for the tensor product of Hilbert spaces ...

Tensor product dual frames

Journal of Inequalities and Applications, 2019
To construct dual frames with good structure for a given frame is a fundamental problem in the theory of frames. The tensor product duals of tensor product frames can provide a rank-one decomposition of bounded antilinear operators between two Hilbert ...

Numerical radius inequalities for tensor product of operators [PDF]

Proceedings - Mathematical Sciences, 2022
The two well-known numerical radius inequalities for the tensor product $$A \otimes B$$ A ⊗ B acting on $${\mathbb {H}} \otimes {\mathbb {K}}$$ H ⊗ K , where A and B are bounded linear operators defined on complex Hilbert spaces $${\mathbb {H}} $$ H and $

Dimensionality Reduction with Variational Encoders Based on Subsystem Purification

Mathematics, 2023
Efficient methods for encoding and compression are likely to pave the way toward the problem of efficient trainability on higher-dimensional Hilbert spaces, overcoming issues of barren plateaus.

Product of random states and spatial (half-)wormholes

Journal of High Energy Physics, 2021
We study how coarse-graining procedure of an underlying UV-complete quantum gravity gives rise to a connected geometry. It has been shown, quantum entanglement plays a key role in the emergence of such a geometric structure, namely a smooth Einstein ...

Generalization of the Tensor Product Selected CI Method for Molecular Excited States. [PDF]

Journal of Physical Chemistry A, 2023
In a recent paper [JCTC, 2020, 16, 6098], we introduced a new approach for accurately approximating full CI ground states in large electronic active-spaces called Tensor Product Selected CI (TPSCI).

Efficient and flexible approach to simulate low-dimensional quantum lattice models with large local Hilbert spaces

SciPost Physics, 2021
Quantum lattice models with large local Hilbert spaces emerge across various fields in quantum many-body physics. Problems such as the interplay between fermions and phonons, the BCS-BEC crossover of interacting bosons, or decoherence in quantum ...
