In quantum information and communication, optical schemes provide simple and intuitive experimental implementations. Of particular importance is quantum state preparation. In this thesis, the creation of polarisation entanglement using a particular class of optical circuits is studied. I give a mathematical description of this class of circuits in terms of Hermite polynomials. In this context, single photon resolution and single photon sensitivity detectors are discussed and compared with detector cascading. In addition, I study applications of state preparation such as quantum teleportation and quantum lithography.

  1. Rigorous no-go theorems for heralded linear-optical state generation tasks

    quant-ph 2026-02 conditional novelty 6.0 of 10

    Applying the NulLA algorithm proves no-go theorems for heralded linear-optical state generation, showing e.g. that Bell states need ≥4 input photons and a heralded CNOT gate needs ≥2 ancilla photons.
