Tensor Decomposition for Non-Clifford Gate Minimization
Kirill Khoruzhii, Patrick GelÃ, Sebastian Pokutta
Fault-tolerant quantum computation requires minimizing non-Clifford gates, whose implementation via magic state distillation dominates the resource costs. While -count minimizat…

Quantum dynamics of coupled excitons and phonons in chain-like systems: tensor train approaches and higher-order propagators
Patrick GelÃ, Sebastian Matera, Rupert Klein +1
We investigate tensor-train approaches to the solution of the time-dependent Schrödinger equation for chain-like quantum systems with on-site and nearest-neighbor interactions onl…
