Unifying the Clifford Hierarchy via Symmetric Matrices over Rings
Narayanan Rengaswamy, Robert Calderbank, Henry D. Pfister
The paper shows that diagonal gates in the Clifford hierarchy can be described by quadratic forms over the integer ring \(\mathbb{Z}_{2^k}\) using symmetric matrices, linking these…
Quantum algorithm for calculating molecular vibronic spectra
Nicolas P. D. Sawaya, Joonsuk Huh
