 Compared to other libraries for quantum information processing, qutip-qip puts additional emphasis on the physics layer and the interaction with the QuTiP package.
 The package offers two different approaches for simulating quantum circuits, one with `QubitCircuit` calculating unitary evolution under quantum gates by matrix product, another called `Processor` using open system solvers in QuTiP to simulate noisy quantum device.
