Exact Separation of Words via Trace Geometry
Zeyu Chen, Junde Wu
A basic question in the study of measure-once quantum finite automata is whether two distinct input words can be separated with certainty. The exact separation problem reduces to a…

Rational-Valued Affine Verifiers in Arthur--Merlin Proof Systems
Zeyu Chen, Junde Wu
Affine automata provide a finite-state computational model that preserves the linear-algebraic structure of quantum computation while operating entirely over the reals. Recent work…

Implementation of Quantum Fourier Transform and Quantum Hashing for a Quantum Device with Arbitrary Qubits Connection Graphs
Kamil Khadiev, Aliya Khadieva, Zeyu Chen +1
In the paper, we consider quantum circuits for Quantum fingerprinting (quantum hashing) and quantum Fourier transform (QFT) algorithms. Quantum fingerprinting (quantum hashing) is…
