Quantum technology based on the quantum mechanics and optical physics to meet the grand challenge of new principles for sensing and information transfer in the photonic layer. An important aspect of the is quantum technologies is the development of new cryptosystem. Quantum networking research is giving rise to the field of quantum internet. This will involve the use of quantum computing in the application layer, quantum repeaters in the quantum transport or teleportation layer, and quantum end nodes or gateways in the quantum network layer. Photonic quantum sensors based on avalanche photodiodes for entangled photon detection will be included in the sensor nodes for the quantum internet of things as an example. Quantum optical sensors can be used for quantum metrology, quantum lithography or for the quantum radar and detecting gravitational waves. The quantum internet of things as a part of the quantum internet will utilize a quantum approach to security. Since the implementation of quantum networks with quantum internet of things would allow for quantum cryptography. This paper provides a brief analysis of quantum techniques for modern communications. The paper discusses the main entities of a quantum network, quantum sensor, and quantum internet. It considers an architecture for quantum internet of things representation based on the quantum networks. A proposed integrated functional architecture for quantum internet of things will be presented, which will include quantum key distribution, quantum teleportation, and quantum sensing will be proposed.
