“…the error propagates along the swapping route. All these considerations would require a more refined physical model, which would in turn imply revisions to our mathematical framework, but should not be excessively difficult to include in the numerical part of our discussion: the simulator code was written from the ground up in order to provide a simpler and more agile contribution, but it was designed with particular attention to keeping a layered and modular structure that should be reasonably adaptable to well-established quantum network simulation packages such as NetSquid [47] or QuISP [48].…”

Quantum Internetworking is a recent field that promises numerous interesting applications, many of which require the distribution of entanglement between arbitrary pairs of users. This work deals with the problem of scheduling in an arbitrary entanglement swapping quantum network -often called first generation quantum network -in its general topology, multicommodity, loss-aware formulation. We introduce a linear algebraic framework that exploits quantum memory through the creation of intermediate entangled links. The framework is then employed to apply Lyapunov Drift Minimization (a standard technique in classical network science) to mathematically derive a natural class of scheduling policies for quantum networks minimizing the square norm of the user demand backlog. Moreover, an additional class of Max-Weight inspired policies is proposed and benchmarked, reducing significantly the computation cost at the price of a slight performance degradation. The policies are compared in terms of information availability, localization and overall network performance through an ad-hoc simulator that admits userprovided network topologies and scheduling policies in order to showcase the potential application of the provided tools to quantum network design.

“…The research community has developed several approaches to quantum network architecture and protocol design [22], [24], [25] as well as quantum network simulators to implement and evaluate them, such as QuISP [46], SeQUeNCe [25], and NetSquid [47]. However, the simulators do not share any tooling nor a common node architecture, which has resulted in protocol implementations that are tightly coupled to their simulators.…”

Quantum entanglement is so fundamentally different from a network packet that several quantum network stacks have been proposed; one of which has even been experimentally demonstrated. Several simulators have also been developed to make up for limited hardware availability, and which facilitate the design and evaluation of quantum network protocols. However, the lack of shared tooling and community-agreed node architectures has resulted in protocol implementations that are tightly coupled to their simulators. Besides limiting their reusability between different simulators, it also makes building upon prior results and simulations difficult. To address this problem, we have developed QuIP: a P4-based Quantum Internet Protocol prototyping framework for quantum network protocol design. QuIP is a framework for designing and implementing quantum network protocols in a platform-agnostic fashion. It achieves this by providing the means to flexibly, but rigorously, define device architectures against which quantum network protocols can be implemented in the network programming language P416. QuIP also comes with the necessary tooling to enable their execution in existing quantum network simulators. We demonstrate its use by showcasing V1Quantum, a completely new device architecture, implementing a link-and network-layer protocol, and simulating it in the existing simulator NetSquid.

“…Our design and assumptions of the error propagation follow those in Ref. [53], which tracks information about whether a qubit has been affected by a Pauli Z and/or X error along with a time stamp when it was initiated. We now summarize the error sources which contribute towards the degradation of the fidelity of the end-to-end entangled state.…”

“…To simulate the complex behavior of the quantum network, time delay and resource management, we use SimPy, the discrete-event simulation package written in Python. For noise simulation, as large quantum systems needed to be simulated, similarly to Stabilizer formalism, we use error-basis model [53] which collects only the information about the noise of each qubit thus allow us to efficiently simulate the system. Although this is not the representation of a quantum state, the choice is preferred as it is relatively easier to implement and the information of the noise is enough to be used for the fidelity discussed in Section 2.3.…”

A quantum network is expected to enhance distributed quantum computing and quantum communication over a long distance while providing unconditional security. As quantum entanglement is essential for a quantum network, major issues from various types of noise and decoherence prevent it from being realized, and research has been intensively active to obtain optimal configurations for a quantum network. In this work, we address the performance of a quantum network capable of quantum error correction and entanglement purification. Our results show that one should distribute Bell pairs as fast as possible while balancing the deployment of fidelity enhancement. We also show suitable hybrid strategies in quantum cryptography tasks under some noise regimes that need to use purification and quantum error correction together. Our results suggest that using purification to distribute high fidelity Bell pairs and preserving them for application using quantum error correction is a promising way to achieve a near-term quantum network for secure communication.
