# Journal club ideas ## Bristol LOQC key papers ### [Error protected photonic qudits](https://www.nature.com/articles/s41567-021-01333-w) * This work is an experimental demonstration of quantum information protected by encoding. * There is no error-correction. * Everything is still based on post-selection. ### [Quantum information processing with remote connections](https://www.nature.com/articles/s41567-019-0727-x.pdf) * This work covers various quantum information processing including quantum teleportation with a chip-to-chip quantum interconnect. * Looks like a good material to learn how quantum information processing is getting done in LOQC. ## Quantum information theory for LOQC ### [Resource-Efficient Linear Optical Quantum Computation](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.95.010501) * First work that describes the fusion operation. * LOQC's strategy to build larger entangled state is based on this seminal work. ### [From Three-Photon Greenberger-Horne-Zeilinger States to Ballistic Universal Quantum Computationn](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.115.020502) * First work that descrbies ballistic operation is useful for scalable quantum computation. ### [Creation of Entangled Photonic States Using Linear Optics](https://arxiv.org/pdf/2106.13825.pdf) * Strategy for enlarging entangled states is described well here. * It is based on Dr. Terry Rudolph's two previous works: fusion and ballistic operation. ## Internal tutorial production ### Summarize the purity measurement methods * Start from this paper: [Probing multimode squeezing with correlation functions](https://iopscience.iop.org/article/10.1088/1367-2630/13/3/033027)
