A quantum internet is a network that transmits information using quantum states of particles, typically photons, rather than classical bits. Unlike conventional networks, which send data as 0s and 1s, quantum networks use qubits, which can exist in multiple states simultaneously due to superposition. Qubits can also be entangled, meaning the state of one qubit instantaneously affects its entangled partner, regardless of distance. This allows for ultra-secure communication, quantum key distribution (QKD), and distributed quantum computing .
Quantum networks rely on several key principles:

End nodes can both receive and emit information. Telecommunication lasers and parametric down-conversion combined with photodetectors can be used for quantum key distribution. In this case, the end nodes can in many cases be very simple devices consisting only of beamsplitters and photodetectors. However, for many protocols more sophisticated end nodes are desirable. These sy
