# The MadQCI Cloud Scenario: Quantum as a Service

## 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.

## Key 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.
