“…Future uses of OpenFlow for quantum networking will require tracking of additional metadata, most notably, metadata to define the state of quantum switches and routers. 26 Quantum switches represent a component of the quantum network responsible for connecting devices over established input and output paths. Because quantum optical states cannot be copied or probed during transmission, management of network switching and routing must occur by sharing metadata across the network.…”

“…We currently use these simulations as a fundamental demonstration of how the quantum device can be integrated with the SDN controller. While our efforts to model the underlying protocols are ongoing [29], we have used this functional model to verify the protocol syntax. In particular, every time an attribute is changed or updated, the OpenFlow agent on the device updates the SDN controller with new metadata that is in turn made available to all other quantum devices under its control as needed.…”

Quantum networks must classically exchange complex metadata between devices in order to carry out information for protocols such as teleportation, super-dense coding, and quantum key distribution. Demonstrating the integration of these new communication methods with existing network protocols, channels, and data forwarding mechanisms remains an open challenge. Software-defined networking (SDN) offers robust and flexible strategies for managing diverse network devices and uses. We adapt the principles of SDN to the deployment of quantum networks, which are composed from unique devices that operate according to the laws of quantum mechanics. We show how quantum metadata can be managed within a software-defined network using the OpenFlow protocol, and we describe how OpenFlow management of classical optical channels is compatible with emerging quantum communication protocols. We next give an example specification of the metadata needed to manage and control QPHY behavior and we extend the OpenFlow interface to accommodate this quantum metadata. We conclude by discussing near-term experimental efforts that can realize SDN's principles for quantum communication.Quantum information theory promises a variety of new techniques for transmitting, protecting, and processing information that may benefit the efficiency, security, and speed of tactical communication networks. This includes higher bandwidth encodings on network links, idealized encryption between network nodes, and faster, distributed computation across the network topology. These capabilities could offer disruptive advances in military communication networks. However, quantum information theory also imposes constraints on the operation of a quantum network including, for example, nocloning and no-broadcasting. Therefore, conventional network engineering methods are unlikely to apply to the construction of future quantum networks, and new methods for quantum network engineering and management are needed to address different use cases. While multiple experimental demonstrations have validated these ideas, demonstrating the integration of quantum communication methods with existing protocols, channels, and data forwarding mechanisms is an open challenge.Software-defined networking (SDN) is an emerging and fast growing technology for interconnecting network devices and forwarding packets based on unified policies and security enforcements. SDN capabilities have also been recently highlighted as an important enabling capability for military tactical networks, where assured networking is critical and flexible management are needed. The defining feature of SDN is deep programmability of the network at all layers including the extension of the network state into applications for enabling better pathing decisions. This versatile and programmable network architecture is expected to be more suitable to support future heterogeneous systems and implement ad hoc network policies, for example, that may arise in tactical environments. This includes quantum communication model...

“…A software-defined quantum communication framework has been presented in [358], where a quantum communication terminal was represented in form of three layers, i.e., hardware, middleware, and software layers. In [359], a programmable multi-node quantum network was designed based on the SDN principles. Dasari et al [360] described the network abstraction and configuration interfaces required for implementing a SDN-enabled programmable quantum network.…”

“…Planned technological advances in quantum annealing architectures will also make possible tighter integration of quantum and classical components in the hybrid approaches discussed above, both through more programmable devices that allow for greater flexibility as subroutines and through application-specific devices that maximize the effectiveness of particular algorithms. In future, we expect quantum hardware to be integrated into larger systems much as graphical processing units are today [19].…”

In the last couple of decades, the world has seen several stunning instances of quantum algorithms that provably outperform the best classical algorithms.For most problems, however, it is currently unknown whether quantum algorithms can provide an advantage, and if so by how much, or how to design quantum algorithms that realize such advantages. Many of the most challenging computational problems arising in the practical world are tackled today by heuristic algorithms that have not been mathematically proven to outperform other approaches but have been shown to be effective empirically. While quantum heuristic algorithms have been proposed, empirical testing becomes possible only as quantum computation hardware is built. The next few years will be exciting as empirical testing of quantum heuristic algorithms becomes more and more feasible. While large-scale universal quantum computers are likely decades away, special-purpose quantum computational hardware has begun to emerge that will become more powerful over time, as well as some small-scale universal quantum computers. * Rupak Biswas
