Mean-State Entropy Hierarchies and Classical Communication through Quantum Convolutions
Chunhe Xiong, Sunho Kim, Qing-hua Zhang +2
Quantum convolution provides a discrete-variable analogue of classical convolution, with the mean state capturing the stabilizer structure preserved under repeated convolution. We…
Private Capacity of Quantum Channels Induced by Non-stabilizer Environmental States
Chunhe Xiong, Sunho Kim, Long Long +1
We investigate the private capacity of quantum channels using the recently proposed quantum convolution theory for discrete-variable quantum systems. We focus on the role of the ma…
On the Simulation Cost of Quantum Finite Automata
Zeyu Chen, Junde Wu
This paper identifies exact probabilistic simulation cost as the natural quantitative measure of quantum advantage for finite automata under strict cutpoints. It gives sharp simula…
Matrix encoding method in variational algorithm of calculating eigenvalues and generalized eigenvalues
Alexander I. Zenchuk, Junde Wu
We propose a variational method for constructing the eigenvalues and generalized eigenvalues for an arbitrary complex matrix. The quantum part of our algorithm is based…
The State Cost of Classical Simulation of One-Way General Quantum Finite Automata
Zeyu Chen, Junde Wu
Under strict cutpoints, probabilistic finite automata (PFAs) and one-way general quantum finite automata (1gQFAs) recognize the same stochastic languages, shifting the theoretical…
