Quantum algorithm can be used to optimize telecommunications networks

Informative summary

  • Cinfo and Kipu Quantum and R use quantum computing to improve the Galician operator’s fiber optic backbone network.
  • The quantum algorithm identifies the most sensitive nodes, which could have the greatest impact on the service in the event of a disconnection or breakdown.
  • The information allows us to focus on those points detected with current quantum technology and anticipate counterattacks.

PRESS RELEASEThe project, promoted by Cinfo and Kipu Quantum on the R infrastructure, applies the computing capacity that quantum computing offers today to the Galician operator’s fiber optic backbone network, examining its robustness and resilience in the event of possible outages and/or critical situations.

The newly designed quantum algorithm identifies the most sensitive nodes, which could have the greatest impact on service in the event of a disconnection or failure. This relevant information allows us to focus on those points detected with current quantum technology and anticipate counterattacks, achieving a maximum rate of network availability and service excellence.

Cinfo, which has developed the network model adapted to the capabilities of accessible quantum computers, has had the support of Kipu Quantum, which has been in charge of preparing the quantum algorithm model to analyze the R backbone network.

Norberto Ojinaga, Director of Technological Solutions at R and the MASMOVIL Group, believes that “the use case considered is a realistic instance that allows a significant improvement in the quality and guarantee of the service that, as a telecommunications operator, we want to offer our clients. ”. customers”.

Furthermore, Isidro Fernández de la Calle, Business Director of R y Grupo MASMOVIL, explains that “we express our strong commitment to providing our clients with a robust and resilient network in the event of the most adverse circumstances; Therefore, we cannot neglect the advances that quantum computing now offers to simulate and prepare our environments to be managed with the maximum guarantee.”

Analysis in two phases: quantum annealing and neutral atoms.

Unlike classical computing, and thanks to the large number of qubits of neutral atom quantum computers (256 currently and around 1,000 expected in about a year), the piloted quantum algorithm consumes the same time regardless of the number of nodes in the network.

In the first phase of the R-Cinfo-Kipu project, an analysis of each node has been carried out with currently available quantum computers. Specifically, an initial classification of the network topology has been carried out with a quantum annealing in 180 of the 5,627 qubits available on the D-Wave company’s quantum computers, allowing for sensitive network segmentation.

In the second phase, related to the examination of subnetworks, the QuEra quantum computer based on neutral atom technology was used with 20 qubits for the solution of the main lattice structure and 46 qubits for the combined subnet structure.

This pioneering hybrid solution architecture employing various quantum computing technologies has been made possible by commercial access offered by providers through cloud services. Access to the QuEra platform is enabled by the AWS Braket service, while D-Wave provides its own services. Quantum computing capabilities in the cloud made these combined solutions possible by extracting the best from each of them.

The general director of Cinfo, Antonio Rodríguez del Corral, points out that “at Cinfo we have accepted the challenge of creating valuable quantum computing use cases for the industry. To do this, we are developing a team of professionals – graduates in Physics from the University of Santiago de Compostela – and selecting technological partners who will introduce us to the design of quantum algorithms and the understanding of the different capabilities of existing quantum computers. like Kipu Quantum.”

For Rodríguez del CorralTechnology companies are needed to identify business problems that quantum computing can help with, because the customer does not have to know the details of a complex field that evolves at high speed. We are trying to find unsolved business problems in large companies and see if quantum computing can offer better solutions. “Once the challenge has been identified, the most appropriate algorithm and quantum hardware will need to be chosen, which may change over time as quantum computers develop.”

Regarding the analysis carried out on the R network, the CEO of Cinfo explains that “the optimization of network traffic is always a key issue and, in complex networks such as the R network, it may require quantum computing. We proposed it, confirmed the fit and this project was born.”

On the other hand, the visionary director of Kipu Quantum, Enrique Solano, comments that “quantum computers with digital, analog and digital-analog encoding will approach the quantum advantage for industrial use cases this year. Projects such as the one developed with R and Cinfo represent a step forward towards the practical use of quantum processors with hundreds of qubits. Kipu Quantum is proud to contribute to the leaders and pioneers of the Galician quantum pole in the use of quantum technologies.”

The general director of Kipu Quantum, Daniel Volz, believes that “this project should lay the foundations for a long and fruitful collaboration with Cinfo, with the industry and the Galician business community, as well as with the Spanish technological ecosystem on our joint path towards utility. of quantum computers in Europe.

So much quantum hardware Companies and algorithm providers have taken on the challenge of achieving a quantum advantage in the near term, possibly within a couple of years. The startup Kipu Quantum aims to achieve this as soon as possible with its application- and hardware-specific algorithms, which adapt to existing needs. hardware. Additionally, Kipu Quantum has maximum compression (i.e. reduction of algorithms in quantum devices) with digital, analog and digital-analog encoding in optimization, logistics, finance and artificial intelligence, as well as in the design of chemical molecules and materials. . In this way, the best solutions can be extracted from quantum processors with qubits encoded in trapped ions, neutral atoms or superconducting circuits.

Points for improvement in a realistic case

The topology of an advanced fiber network infrastructure like R’s requires a detailed study of the connectivity of its nodes and strategic points to facilitate an evaluation of its strength. For this reason, R has become a use case for Cinfo. In this sense, by running algorithms or models through quantum computers, it is possible to detect points of improvement in the network and draw conclusions to act and solve.

As quantum computers become more powerful, a greater number of more complex variables can be incorporated into algorithmic study. In this way, the path marked by this Cinfo project, in collaboration with its expert partner Kipu Quantum, will continue and exploit the more than predictable improvements in quantum hardware. In fact, it is expected that in 2025 these supercomputers will already be capable of processing the algorithm of a complex network such as the backbone of R and the entire MASMOVIL Group; Basically, as the infrastructure grows, it is optimized and perfected.

All this shows that the use of quantum computing for the analytical and complete resolution of common problems in the industry is imminent. This will allow us to rule out current approaches based on brute force and experience, which are not always effective in anticipating all scenarios.
