• Abstract: We introduce groundbreaking techniques in image encryption, assuming the existence of quantum computing ressources functioning with qudits, where d is a power of 2. Our quantum representation of color multi-image is based on space-filling curves and allows to reduce the storage space. We generalize the quantum baker map, so that it may scramble two n-qudits. By doing so, we enlarge its parameter space exponentially, leading to a better security. We define two new concepts of mixed scrambling and mixed diffusion, and present a variety of schemes, depending on the needs of the users.

  We use the open-source Simulator of QUantum Network Communication (SeQUeNCe), developed by our team, to simulate entanglement generation between two atomic frequency comb (AFC) absorptive quantum memories. We realize the representation of photonic quantum states within truncated Fock spaces in SeQUeNCe. We observe varying fidelity with SPDC source mean photon number, and varying entanglement generation rate with both mean photon number and memory mode number.
