AQC-Tensor Qiskit addon¶
This addon lets a Qiskit user perform approximate quantum compilation by using tensor networks, a technique that was introduced in arXiv:2301.08609.
Specifically, with this package you can compile the initial portion of a circuit into a nearly equivalent approximation of that circuit, but with fewer layers.
It has been tested primarily on Trotter circuits to date. It might, however, be applicable to any class of circuits where you have access to both of the following:
A great intermediate state, known as the “target state,” that can be achieved by tensor-network simulation
A good circuit that prepares an approximation to the target state, but with fewer layers when compiled to the target hardware device
