Abstract
The disclosure relates to a node of a network, the node comprising a monolithically integrated entropy source having: a photon source that is designed to emit photons, the photon source comprising a first outer shell, said first outer shell being formed by a first base surface, a first top surface, and at least one first side surface connecting the first base surface and the first top surface to one another; and a photon detector that is designed to detect the photons emitted by the photon source, the first base surface of the photon source being arranged so as to face the photon detector.
Claims26
A node of a network, wherein the network is configured to connect the node with a plurality of further nodes in such a way that data between the nodes can be exchanged via the network, comprising a quantum random number generator, wherein the quantum random number generator includes:
- a monolithically integrated entropy source, wherein the entropy source includes a photon source configured to emit photons, wherein the photon source includes an outer shell, wherein the outer shell is formed by a base surface, a top surface and at least one side surface connecting the base surface and the top surface, and a photon detector designed to detect the photons emitted by the photon source, wherein the base surface of the photon source is arranged facing the photon detector, wherein the base surface of the photon source is formed in a two-dimensional plane, with a normal vector perpendicular to the base surface pointing in a direction of the photon detector, and
- an electronic circuit designed to generate a random bit depending on an output signal of the entropy source, wherein a characteristic of the output signal of the entropy source depends on a temporal frequency of the photons detected by the photon detector.
