Jaime S. Buruaga, Alberto Sebastián-Lombraña, Ruben B. Méndez, Rafael J. Vicente, Juan P. Brito, Laura Ortiz, Vicente Martin

TL;DR
The MadQCI project provides quantum communication services in a cloud-like format, making quantum technology accessible to users without technical expertise.
Contribution
The paper introduces a cloud-based quantum service model that abstracts technical complexity for end users.
Findings
Quantum services like SD-QKD, QRNG, and Quantum-Safe TLS are delivered via a cloud-based XaaS model.
The MadQCI infrastructure promotes quantum technology adoption by simplifying user interaction.
The approach is applied and transferable for broader quantum service deployment.
Abstract
Within the Madrid Quantum Communication Infrastructure (MadQCI), a cloud-like, quantum-enabled network scenario has been commissioned to promote the growth of the quantum technology scientific community. This scenario is designed to provide both quantum communication primitives and quantum-enabled services to potential end users. This work focuses on exposing these quantum services in a user-friendly manner by abstracting the underlying technical complexity, letting end users operate without prior knowledge of implementation details. To this end, multiple quantum services—the SD-QKD software stack, QRNG, Quantum-Safe TLS, and Quantum-Safe IPsec as a Service—are offered following the cloud “anything as a service” (XaaS) model. The delivery of quantum-enabled services is therefore researched using an applied and transferable cloud-based paradigm.
