Entanglement Detection for Two-Qubit and Three-Qubit Pure States via Unitary Transformations and Ancilla State Measurements
Yu-Hang Liu, Yuan-Hong Tao, Yi-Wen Liu +2
The paper presents quantum circuit designs that use unitary operations and ancilla qubits to directly measure two-qubit concurrence and three-qubit 3‑tangle, avoiding full state to…
Quantum Circuit Implementation of Two Matrix Product Operations and Elementary Column Transformations
Yu-Hang Liu, Yuan-Hong Tao, Jing-Run Lan +1
This paper focuses on quantum algorithms for three key matrix operations: Hadamard (Schur) product, Kronecker (tensor) product, and elementary column transformations each. By desig…
Quantum Algorithms for Matrix Operations Based on Unitary Transformations and Ancillary State Measurements
Yu-Hang Liu, Yuan-Hong Tao, jing-Run Lan +1
MQuantum algorithms of matrix operations are of great significance in many fields in science and technology. In this paper, by leveraging multi-qubit Toffoli gates and basic single…
Basis-independent Coherence and its Applications
Zhi-Xiang Jin, Yuan-Hong Tao, Bing Yu +1
In the quantitative theory of quantum coherence, the amount of coherence for given states can be meaningfully discussed only when referring to a preferred basis. One of the objecti…
