Company
Who we are.
A Spanish National Research Council (CSIC) spin-off building quantum-secure communication systems for European infrastructure.
Mission
Frontier science, pragmatic engineering.
Q-Dynamics is a CSIC spin-off based in Madrid, with roots in two decades of fundamental research in quantum optics. We build systems that bridge the rigour of physics and the real-world requirements of network operators, enterprises and institutions.
Europe is building a sovereign quantum communication infrastructure: EuroQCI. Spain’s Quantum Technologies Strategy 2025–2030 allocates €808M of public funding, with quantum communications as one of its three pillars.
Scientific integrity
Claims backed by peer-reviewed research and measured results.
Transparency
We explain our technology plainly, from the CISO to the policymaker.
European sovereignty
Europe’s critical infrastructure must be secured with European technology.
Interoperability
Systems designed to work with existing infrastructure, not against it.
Team · Physicists and engineers
From the lab to the network.
A team shaped by quantum optics research at CSIC, now focused on turning that science into deployable systems.
Verónica Fernández
Co-founderLead Technical Officer
Leads the technical direction of Q-Dynamics. She holds a PhD in Physics from Heriot-Watt University and was a tenured scientist at CSIC, where she led the creation of its quantum communications laboratory. Her research covers high-speed quantum key distribution (QKD) over fibre and free space, and laser beam stabilisation against atmospheric turbulence.
Aida García Callejo
Co-founderSecurity and post-processing, technical project management
Leads the security and post-processing of Q-Dynamics’ QKD systems and for the technical management of its projects. With a background in mathematics and physics, she was formerly a member of CSIC’s Cryptology and Information Security group, and has published on continuous-variable QKD security and pilot-assisted frequency locking.
Andrés Ruiz Chamorro
Co-founderHead of CV-QKD
Heads the continuous-variable QKD (CV-QKD) line of Q-Dynamics. A physicist, he completed his PhD at CSIC with a thesis on the design of a CV-QKD system (Complutense University of Madrid, 2025). He has published on pilot-assisted frequency locking and CV-QKD security, and develops the post-processing and control software.
Pablo Arteaga Díaz
Co-founderHead of DV-QKD free space
Heads the free-space discrete-variable QKD (DV-QKD) line of Q-Dynamics. He completed his PhD at CSIC with a thesis on robust QKD systems for aerial channels (Complutense University of Madrid, 2024). His work covers optical ground station design, beam stabilisation and satellite QKD, as well as the Madrid Quantum Network free-space link.
Adrián Llanos Velasco
Co-founderHead of electronics
Leads electronics development at Q-Dynamics. An industrial electronics and automation engineer with a master’s degree in automation and robotics, he worked in CSIC’s quantum communications group on laser beam pointing and tracking, polarisation tracking and adaptive optics, for both the fibre CV-QKD and free-space DV-QKD lines.
