AKLT ground state in "Bosonic Qiskit"

A collaboration within the Co-design Center for Quantum Advantage (C2QA) is currently building an instruction set architecture for hybrid qubit/oscillator circuit QED hardware using Qiskit, the IBM open-source software development kit (SDK). Qiskit has been designed to operate on two-level systems. The aim is to create a branch of Qiskit called "Bosonic Qiskit" which can accommodate continuous variable systems with a view to using "Bosonic Qiskit" to represent circuit QED hardware in the future. As a proof of concept of "Bosonic Qiskit", we use it to implement a symmetry protected topological state - the seminal AKLT chain - using the native bosonic operations made available in the SDK.
