Matías R. Bolaños defended his PhD thesis
We are proud to announce that on February 11, 2026, Doctoral Candidate Matías R. Bolaños successfully defended his PhD thesis, marking a significant milestone in the advancement of high-performance quantum communication technologies.
Dr. Matías Rubén Bolaños Wagner presented his dissertation entitled “Development of High Performance Systems for Quantum Communications”, a comprehensive work focused on the design and implementation of high-performance hardware platforms for both discrete-variable (DV) and continuous-variable (CV) quantum communication systems.
His research bridges FPGA-based digital logic, advanced optoelectronic control, and quantum optics to create fast, stable, and fully reconfigurable experimental platforms. These systems are engineered to meet the demanding performance requirements of next-generation quantum key distribution (QKD) networks.
Among the key achievements of the thesis are:
- High-speed DV-QKD hardware architectures, including polarization-encoded sources operating at gigahertz repetition rates.
- Time-bin encoded quantum sources capable of supporting high-dimensional quantum states with excellent phase stability.
- Advanced digital signal processing frameworks for CV-QKD, implemented within the same hardware ecosystem.
- Demonstration of coexistence between DV and CV quantum schemes within the same optical channel, an important step toward hybrid and scalable quantum networks.
By extending a unified hardware framework across DV and CV paradigms, Dr. Bolaños’ work demonstrates how performance, stability, and scalability can be simultaneously achieved. His contributions represent a significant step toward practical, large-scale QKD deployments and the realization of robust quantum-safe communication infrastructures.
This achievement aligns closely with the mission of Quantum Safe Internet: advancing the technologies that will secure tomorrow’s communications against quantum-enabled threats. We warmly congratulate Dr. Bolaños on this outstanding accomplishment and look forward to the continued impact of his work in the field of quantum communications.
