Aliro Deploys Quantum-Secure Communication Testbed BrightNet
Aliro, a trailblazing quantum technology company, has successfully developed and deployed BrightNet, a quantum-secure communication testbed powered by quantum fiber. This significant achievement was made possible by Aliro Simulator, a digital laboratory that enabled the intricate mapping of quantum states and entanglement distribution before any physical implementation.
Aliro's engineers approached the network as a delicate ecosystem, carefully harmonising hardware components, optical fibers, and environmental conditions. The Aliro Simulator, with its Python-based API, orchestrated simulation inputs, while its scalable, swappable backend managed quantum state evolution.
The simulator's power was demonstrated when it modeled the impact of temperature fluctuations on the polarisation controller. This led to active temperature regulation in the field, ensuring the resilience of the quantum network. In BrightNet, data is transmitted as fragile quantum states shared between distant parties, Alice and Bob, using the BBM92 protocol for quantum key distribution (QKD).
Iterative refinements using Aliro Simulator significantly reduced the time from concept to deployment of BrightNet, nearly a year. Continuous benchmarking with the simulator helped detect anomalies and maintain the resilience of the live BrightNet network. The simulator accurately predicted key metrics like coincidence rate, quantum bit error rate (QBER), and secure key rate by running the BBM92 protocol in a virtual setting.
Aliro Simulator has proven to be an invaluable tool in the development and deployment of quantum-secure communication systems like BrightNet. By enabling the mapping of quantum states, predicting key metrics, and optimizing network resilience, the simulator has significantly accelerated the process of quantum network development.
