Complexity and Control in Quantum Photonics

The book delves into integrated quantum photonics, showcasing a two-qubit quantum photonic chip that enables arbitrary state preparation. It features a novel implementation of Wheeler's delayed choice experiment and introduces a technique for obtaining nonlocal statistics without a shared reference frame. Additionally, it presents a new quantum chemistry algorithm for simulating the helium hydride ion and explores multiphoton quantum interference in a large Hilbert space, discussing its implications for computational complexity.
