How to Sum and Exponentiate Hamiltonians in ZXW Calculus
Razin A. Shaikh, Quanlong Wang, Richie Yeung
This paper develops practical summation techniques in ZXW calculus to reason about quantum dynamics, such as unitary time evolution. First we give a direct representation of a wide…
Annealing Optimisation of Mixed ZX Phase Circuits
Stefano Gogioso, Richie Yeung
We present a topology-aware optimisation technique for circuits of mixed ZX phase gadgets, based on conjugation by CX gates and simulated annealing.
DisCoPy for the quantum computer scientist
Alexis Toumi, Giovanni de Felice, Richie Yeung
DisCoPy (Distributional Compositional Python) is an open source toolbox for computing with string diagrams and functors. In particular, the diagram data structure allows to encode…
Differentiating and Integrating ZX Diagrams with Applications to Quantum Machine Learning
Quanlong Wang, Richie Yeung, Mark Koch
ZX-calculus has proved to be a useful tool for quantum technology with a wide range of successful applications. Most of these applications are of an algebraic nature. However, othe…
