pkg> add CloudQSim
CloudQSim allows to calculate evolution of observables for quantum hamiltonians. Any diagonal observable is supported. An observable is defined by a vector that maps each quantum state to the observable value.
Parameters:
hamiltonians- a Bloqade.jl hamiltoniantime_points- number of poinst in time when observables are evaluatedobservables- Vector of observables to evaluateclconf-CloudQSim.CloudConfigspecifies the servers to usesubspace_radius(optional keyword) - used to generate subspace for faster evolution
