Luces Cuánticas de Madrid: The Second Quantum Revolution.
At LuxQuanta, we believe science and research only reach their full potential when they’re brought into society. That’s why, for the third consecutive year, we joined Luces Cuánticas de Madrid, a special segment of OndaCero’s radio program Más de Uno Madrid to talk about quantum technologies in clear and accessible terms.
In this latest episode, our CEO Vanesa Díaz sat down with journalist Jorge Granullaque to explain the concept of the Second Quantum Revolution. She offered a clear and grounded explanation of why this revolution isn’t just a future possibility, we’re already living it.
WHAT IS THE SECOND QUANTUM REVOLUTION
As Vanesa explained during the interview, most people don’t realise that we’ve already experienced a first quantum revolution. It began in the early 20th century, when scientists uncovered the fundamental laws that govern the smallest elements of the universe: atoms, electrons, photons. This paved the way for inventions like lasers, transistors, and magnetic resonance imaging, the foundation of modern technologies like smartphones, the internet, and advanced medical diagnostics.
“Now, we’re entering the second quantum revolution” said Vanesa. “This time, we’re not just understanding nature, we’re learning how to control it.”
If the first revolution gave us the tools, this second one is about using quantum principles to engineer entirely new systems with unprecedented capabilities. These technologies are generally grouped into three major areas:
- Quantum computing, which promises computational power far beyond the limits of today’s machines.
- Quantum sensing, enabling ultra-precise measurements in fields like medicine and navigation.
- Quantum communications, where LuxQuanta plays a key role — securing digital information using the laws of physics.
Quantum Communications are being deployed.
Among the three fields, quantum computing is often in the spotlight, and with good reason. Global tech giants are racing to build scalable quantum computers. But despite real progress, universal machines are still not yet practical.
Quantum sensing is less well known, but it’s already delivering results in niche areas. And then there’s quantum communications, which stands apart as the most mature and commercially ready quantum technology, where LuxQuanta is leading in the sector.
“There are already real systems on the market” Vanesa pointed out. “Quantum communications isn’t a promise, it’s a product being deployed in real-world scenarios.”
The main focus in this area is quantum cryptography, and more specifically, Quantum Key Distribution (QKD). QKD uses the principles of quantum mechanics to securely generate and distribute cryptographic keys between two endpoints, not through algorithms, but through the behaviour of quantum particles. If anyone tries to intercept or measure the transmission, the data is altered, making eavesdropping not just difficult, but physically impossible.
“Even when a quantum computer arrives, it won’t be able to break this kind of encryption. That’s why we say we have a window of time, to make infrastructures quantum-safe before those machines exist.”
In short, quantum communications is how we future-proof digital security, from personal data and health records to government systems and national networks.
SPAIN IS LEADING THE QUANTUM ECOSYSTEM
There’s a common perception that Europe is lagging in the global quantum race. But as Vanesa clarified, Europe is actually leading in quantum initiatives, where Spain positions as one the main countries leading the adoption and development of new quantum technologies.
“We’re not starting from zero , and that’s what I keep telling the government” she shared. “We have not only great talent, but a growing and powerful business ecosystem that will help mature these technologies for real commercial use.”
Spain already has:
- Three companies building quantum hardware across different specialisations: LuxQuanta (QKD), Quside (QRNG), Qilimanjaro (Quantum Computers).
- Startups like Qoolnet developing software layers for quantum networks (KMS)
- Academic leadership, particularly from the Polytechnic University of Madrid, where Vicente Martín’s team built the Madrid Quantum Communications Network, the largest operational quantum network in Europe.
“From research centres to companies like Telefónica, Spain has a strong ecosystem and a clear roadmap,” Vanesa said.
WHY QUANTUM MATTERS NOW
Quantum technologies are no longer just a scientific milestone. They’re becoming a strategic asset, key to national security, technological sovereignty, and digital resilience.
“This is a collective effort,” Vanesa concluded. “Quantum requires vision, but it also requires execution, and Spain is already executing.”
At LuxQuanta, we believe the Second Quantum Revolution offers more than just new tools. It provides the opportunity to design a digital future that is secure by default.
We’re proud to contribute to that future by making quantum communications real, robust, and ready for deployment.
