QuanteninternetInfrastrukturen

QuanteninternetInfrastrukturen, also known as quantum internet infrastructures, refers to the foundational elements and technologies required to build a functional quantum internet. This network would enable the transmission of quantum information, such as qubits, over long distances, allowing for novel applications in communication, computation, and sensing. Unlike classical internet infrastructures that transmit bits as electrical signals or light pulses, quantum internet infrastructures must handle the delicate nature of quantum states.

Key components of quantum internet infrastructures include quantum repeaters, which are essential for overcoming signal loss in optical fibers. These repeaters are designed to purify and retransmit quantum information, extending the range of quantum communication. Another critical element is the development of robust quantum memory, which can store quantum states for later use. Furthermore, precise control over photons and their entanglement is paramount, necessitating advancements in single-photon sources, detectors, and optical components. The physical layer often relies on low-loss optical fibers, but research also explores free-space quantum communication. Establishing these infrastructures involves significant technological challenges and ongoing research and development.
