Hadamard NMR spectroscopy for two-dimensional quantum information processing and parallel search algorithms [PDF]

, 2006
Hadamard spectroscopy has earlier been used to speed-up multi-dimensional NMR experiments. In this work we speed-up the two-dimensional quantum computing scheme, by using Hadamard spectroscopy in the indirect dimension, resulting in a scheme which is ...

A Characterization of Generalized Boolean Functions Employed in CDMA Communications [PDF]

International Journal of Mathematical, Engineering and Management Sciences
In design of secure cryptosystems and CDMA communications, the negabent functions play a significant role. The generalized Boolean functions have been extensively studied by Schmidt and established several important results in this setup.

Transformer Encoder–Decoder Framework for Nonlinear Pulse Evolution and Inverse Modeling

Advanced Photonics Research, EarlyView.
Modeling nonlinear pulse evolution in optical systems is key to advancing photonic technologies. A transformer‐based encoder‐decoder framework is proposed for both forward and inverse modeling, applied to supercontinuum generation. This approach captures complex dynamics efficiently, outperforming traditional methods in speed.

Interpretable PROTAC Degradation Prediction With Structure‐Informed Deep Ternary Attention Framework

Advanced Science, EarlyView.
PROTAC‐STAN, a structure‐informed deep learning framework is presented for interpretable PROTAC degradation prediction. By modeling molecular hierarchies and protein structures, and simulating ternary interactions via a novel attention network, PROTAC‐STAN achieves significant performance gains over baselines.

Metaheuristics in the Optimization of Cryptographic Boolean Functions

Entropy, 2020
Generating Boolean Functions (BFs) with high nonlinearity is a complex task that is usually addresses through algebraic constructions. Metaheuristics have also been applied extensively to this task. However, metaheuristics have not been able to attain so

A Fourier-analytic Approach to Counting Partial Hadamard Matrices

, 2010
In this paper, we study a family of lattice walks which are related to the Hadamard conjecture. There is a bijection between paths of these walks which originate and terminate at the origin and equivalence classes of partial Hadamard matrices. Therefore,

Quantum‐Inspired Fourier Transforms Based on Circuits

Advanced Science, EarlyView.
An analog scheme of classical circuit for the quantum Fourier transform is proposed. The number of the basic computing components employed in the circuit design is consistent with the number of the quantum gate in the quantum circuit. The information is encoded using correlated electrical signals.
