Tensor Network Assisted Distributed Variational Quantum Algorithm for Large Scale Combinatorial Optimization Problem
Yuhan Huang, Siyuan Jin, Yichi Zhang +3
Although quantum computing holds promise for solving Combinatorial Optimization Problems (COPs), the limited qubit capacity of NISQ hardware makes large-scale instances intractable…
Multi-Channel Currency: A Secure Method Using Semi-Quantum Tokens
Yichi Zhang, Siyuan Jin, Yuhan Huang +1
Digital currencies primarily operate online, but there is growing interest in enabling offline transactions to improve digital inclusion. Existing offline methods struggle with dou…
Cloud-based Semi-Quantum Money
Yichi Zhang, Siyuan Jin, Yuhan Huang +2
In the 1970s, Wiesner introduced the concept of quantum money, where quantum states generated according to specific rules function as currency. These states circulate among users w…
Quantum Graph Optimization Algorithm
Yuhan Huang, Ferris Prima Nugraha, Siyuan Jin +3
Quadratic unconstrained binary optimization (QUBO) tasks are very important in chemistry, finance, job scheduling, and so on, which can be represented using graph structures, with…
