Does qubit connectivity impact quantum circuit complexity?
Pei Yuan, Jonathan Allcock, Shengyu Zhang
Some physical implementation schemes of quantum computing can apply two-qubit gates only on certain pairs of qubits. These connectivity constraints are commonly viewed as a signifi…

Optimal (controlled) quantum state preparation and improved unitary synthesis by quantum circuits with any number of ancillary qubits
Pei Yuan, Shengyu Zhang
As a cornerstone for many quantum linear algebraic and quantum machine learning algorithms, controlled quantum state preparation (CQSP) aims to provide the transformation of $|i\ra…
