Fermionic quantum computation with Cooper pair splitters

The code provides a framework to construct second quantized fermionic Hamiltonians using sympy and obtain effective models using pymablock. The code considers the system dot L --- dot M --- dot R, where L and are R dots that host local fermionic modes and M is the middle dot with finite superconducting pairing \(\Delta\) that mediates coupling between the dots as was shown by Chunxiao et al. We consider the applicability of this system as a fermionic quantum computer as proposed by Bravyi and Kitaev.
