Kevin Shen, Andrii Kurkin, Adrián Pérez-Salinas +3 more·Dec 22, 2024
Expectation Value Samplers (EVSs) are quantum generative models that can learn high-dimensional continuous distributions by measuring the expectation values of parameterized quantum circuits. However, these models can demand impractical quantum resou...
Dynamic T-decomposition for classical simulation of quantum circuits
Wira Azmoon Ahmad, Matthew Sutcliffe·Dec 22, 2024
It is known that a quantum circuit may be simulated with classical hardware via stabilizer state (T-)decomposition in $O(2^{\alpha t})$ time, given $t$ non-Clifford gates and a decomposition efficiency $\alpha$. The past years have seen a number of p...
