Fig. 8: Runtime comparison of NetSquid’s quantum state formalisms.
From: NetSquid, a NETwork Simulator for QUantum Information using Discrete events
Runtime comparisons of the available quantum state formalisms in NetSquid as well as ProjectQ ket vector for two benchmark use cases. The KET, DM, STAB and GSLC formalisms refer to the use of ket vectors, density matrices, stabiliser tableaus and graph states with local Cliffords, respectively. a Generating a Greenberger-Horne-Zeilinger (GHZ) state. Qubits are split off from the shared quantum state after a measurement. For the KET formalism the effect of turning off memoization (dotted line) is also shown. b Quantum computation involved in a repeater chain. Each formalism is shown with qubits split (dotted lines) versus being kept in-place (solid lines) after measurement.
