Use Cases of Quantum Networks for Industry and Science

In the past few years, quantum computers have become increasingly robust and are reaching industrial strength in terms being considered seriously for addressing real life problems. The potential of quantum computers to impact almost every industry vertical and scientific research is well documented. It is only now that this potential can be realized to a certain extent. There are several areas that quantum computing spawns including quantum machine learning, quantum simulation, quantum metrology, quantum cryptography and secure quantum communications. One of the most important applications of secure quantum communications is the quantum network. A quantum network is a complex ecosystem in quantum computing which uses numerous quantum technologies to be implemented including quantum cryptography, quantum entanglement and quantum teleportation. Given the increasing maturity in terms of the hardware required to develop the quantum network, there is a need to focus on identifying and proposing use cases for quantum networks across various industry verticals and scientific domains which may not be implementable using the current classical computing paradigm. This paper evaluates and lists the use cases and applications using the quantum networks. We focus on some of the conventional industry verticals and newer industries and scientific areas where the use cases can be proposed.
