Split-Step Dirac Cellular Automata for Continuous-Time Dirac Dynamics on Finite Spatial Lattices
Wei-Ting Wang, Pei-Ming Ho, Ching-Ray Chang
Dirac Cellular Automata (DCA) provide a framework for simulating Dirac dynamics, yet the rigid coupling between spatial and temporal resolutions can introduce artificial phase-matc…
Quantum Stochastic Walks for Portfolio Optimization: Theory and Implementation on Financial Networks
Yen Jui Chang, Wei-Ting Wang, Yun-Yuan Wang +3
Financial markets are noisy yet contain a latent graph-theoretic structure that can be exploited for superior risk-adjusted returns. We propose a quantum stochastic walk (QSW) opti…
Quantum Walks-Based Adaptive Distribution Generation with Efficient CUDA-Q Acceleration
Yen-Jui Chang, Wei-Ting Wang, Chen-Yu Liu +2
We present a novel Adaptive Distribution Generator that leverages a quantum walks-based approach to generate high precision and efficiency of target probability distributions. Our…
Quantum Entanglement in Dirac Dynamics via Continuous-Time Quantum Walks in a Quantum Circuit Framework
Wei-Ting Wang, Yen-Jui Chang, Ching Ray Chang
We propose a Continuous-Time Quantum Walks (CTQW) model for one-dimensional Dirac dynamics simulation with higher-order approximation. Our model bridges CTQW with a discrete-time m…
A novel approach for quantum financial simulation and quantum state preparation
Yen-Jui Chang, Wei-Ting Wang, Hao-Yuan Chen +2
Quantum state preparation is vital in quantum computing and information processing. The ability to accurately and reliably prepare specific quantum states is essential for various…
Preparing random state for quantum financing with quantum walks
Yen-Jui Chang, Wei-Ting Wang, Hao-Yuan Chen +2
In recent years, there has been an emerging trend of combining two innovations in computer science and physics to achieve better computation capability. Exploring the potential of…
Quantum walk in (1+1)-dimensional spacetime for Majorana dynamics with high order approximation in NISQ
Wei-Ting Wang, Xiao-Gang He, Hsien-Chung Kao +1
In this study, we show that quantum walk can describe a Majorana fermion when the coin operator constrained by Lorentz covariance and the initial state satisfies the Majorana condi…
