Using the methods for optimal simulation of quantum logic gates developed in Ref. [1], we perform a numerical estimation of time and spatial resources involved in the execution of one and two qubit gates for the case of three representative models of quantum computation based on global control. The importance of such models stems from the solution to the problem of experimentally addressing and locally manipulating the qubits in a given quantum register. The numerical estimation of the temporal efficiency for each model is performed by assuming that the qubits are coupled to each other via the Ising interaction whose strength is considered to be of the order of 50 MHz (33 neV).
