qutip-qip v0.1.0

This is the first release of qutip-qip, the Quantum Information Processing package in QuTiP.

The qutip-qip package used to be a module qutip.qip under QuTiP (Quantum Toolbox in Python). From QuTiP 5.0, the community has decided to decrease the size of the core QuTiP package by reducing the external dependencies, in order to simplify maintenance. Hence a few modules are separated from the core QuTiP and will become QuTiP family packages. They are still maintained by the QuTiP team but hosted under different repositories in the QuTiP organization.

The qutip-qip package, QuTiP quantum information processing, aims at providing basic tools for quantum computing simulation both for simple quantum algorithm design and for experimental realization. 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 the execution of quantum circuits on a noisy quantum device.
