Nonlocal Temporal Interferometry for Highly Resilient Free-Space Quantum Communication

Nonlocal Temporal Interferometry for Highly Resilient Free-Space Quantum Communication Entanglement distribution via photons over long distances enables many applications, including quantum key distribution, which provides unprecedented privacy. The inevitable degradation of entanglement through noise accumulated over long distances remains one of the key challenges in this area. Exploiting the potential of higher-dimensional entangled photons promises to address this challenge, but poses extre...
