Status:
Tools for the simulation and execution of quantum annealing algorithms.
Install the package,
] add QuantumAnnealing
Load the package and build a two spin ferromagnetic Ising model for simulation,
using QuantumAnnealing
ising_model = Dict((1,) => 0.1, (1,2) => -1.0)
Perform a basic simulation with an annealing time of 1.0 and a linear annealing schedule,
ρ = simulate(ising_model, 1.0, AS_LINEAR)
print_z_state_probabilities(ρ)
Increase the annealing time to approach the adiabatic limit,
ρ = simulate(ising_model, 5.0, AS_LINEAR)
print_z_state_probabilities(ρ)
Change the annealing schedule and observe different state probabilities,
ρ = simulate(ising_model, 5.0, AS_QUADRATIC)
print_z_state_probabilities(ρ)
