WebbThe time-evolving block decimation (TEBD) algorithm is a numerical scheme used to simulate one-dimensional quantum many-body systems, characterized by at most … The time-evolving block decimation (TEBD) algorithm is a numerical scheme used to simulate one-dimensional quantum many-body systems, characterized by at most nearest-neighbour interactions. It is dubbed Time-evolving Block Decimation because it dynamically identifies the relevant low-dimensional … Visa mer Considering the inherent difficulties of simulating general quantum many-body systems, the exponential increase in parameters with the size of the system, and correspondingly, the high computational costs, … Visa mer The numerical simulation is targeting (possibly time-dependent) Hamiltonians of a system of $${\displaystyle {\it {N}}}$$ particles arranged in a line, which are composed of … Visa mer One thing that can save a lot of computational time without loss of accuracy is to use a different Schmidt dimension for each bond instead of a fixed one for all bonds, … Visa mer Introducing the decomposition of State Consider a chain of N qubits, described by the function $${\displaystyle \Psi \rangle \in H^{{\otimes }N}}$$. … Visa mer One can proceed now to investigate the behaviour of the decomposition D when acted upon with one-qubit gates (OQG) and two-qubit gates (TQG) acting on neighbouring qubits. … Visa mer The errors in the simulation are resulting from the Suzuki–Trotter approximation and the involved truncation of the Hilbert space.
