QKD uses quantum physics to generate and share encryption keys for quantum communication between two network nodes using light over optical fiber.

Quantum computing is changing cybersecurity. Luxquanta brings quantum security solutions for the post-quantum era.
01
Any data sent over a network can be intercepted. Encryption makes that captured data unreadable without the right key.
02
But today’s cryptography won’t be enough for the quantum era. Quantum computers are advancing faster than expected and current methods won’t hold.
03
Luxquanta makes your data infrastructure security quantum-ready. We deliver quantum cryptography that protects sensitive data against tomorrow’s threats, today.
Quantum Key Distribution (QKD) is the most advanced quantum security technology.
Quantum keys
Security is built into the signal itself
Because quantum signals are extremely low-energy, any interception attempt alters the signal and makes it visible.
Built for the quantum era
The result is an ultra-secure, symmetric shared key, resilient against today’s and tomorrow’s cryptographic threats.
The future waits for no one, so neither should you.
It’s time to get Ready. Quantum. Secure.
01
Closer than predicted
Quantum computers are advancing faster than predicted. What once seemed distant is now approaching within real business timeframes, especially for long-lived sensitive data.
02
Data lasts longer
Sensitive data doesn’t age as fast as technology, especially in regulated sectors. Information shared today may still be valuable years from now.
03
No second chance
Waiting means taking a risk you can’t undo. Once data is exposed, it can’t be protected retroactively.
Where security requirements are highest,
quantum-safe protection matters most.
Harvest now, decrypt later threat
Luxquanta delivers physics-based key generation secured by the laws of quantum physics, keeping communications confidential permanently, even against future breakthroughs.
QKD provides future-proof security
Luxquanta’s security is based on physics. The keys don’t rely on algorithms to be solved, so no amount of computational power can compromise them.
Long-lifetime secrets stay secret
Luxquanta’s CV-QKD provides information-theoretic security: keys are protected by physics. Even if traffic is captured today, it remains unreadable forever.
Real-time attack detection
Tamper-evident quantum key exchange provides immediate eavesdropping detection. Operators can respond instantly and protect trust in critical communications.
No new fiber required
CV-QKD integrates into existing optical fibers and coexists with classical data over DWDM, enabling quantum-safe encryption across metro and long-haul networks in weeks.
Compliance and sovereignty are rising
Carrier-grade, standards-aligned CV-QKD for multi-vendor, multi-network environments, supporting sovereignty, regulatory alignment, and long-term compliance.
Trusted by those who know what’s at stake.
“We build what truly matters: protecting the world’s communications not only with technology, but with a team bold enough to turn quantum science into reality.”
- Vanesa Díaz, CEO
“The dream of delivering the technology we were developing in our labs into a product that secures digital communication is now a reality with our QKD solution being deployed across the globe.”
- Sebastián Etcheverry, CTO & Co-founder
“The main innovation at Luxquanta is to use Continuous Variable QKD, as it can be deployed using standard equipment for optical communications and leverage the same optical fiber infrastructure.”
- Jeison Tabares, R&D Engineer
Where quantum-safe transition is essential.
From operators to public institutions, this is where quantum meets cybersecurity.
Telecommunication
network providers
Legally required to protect personal data across complex, evolving networks, where security failures are not an option.
Government
Institutions
Handling sensitive information with direct impact on national security and public trust, where long-term exposure has real consequences.
Critical infrastructure
Secure communications where downtime, failure or compromise can’t be tolerated.
Data centers
Protecting large volumes of data that are constantly stored, processed and accessed, where breaches scale instantly.
Hospitals
and healthcare
Securing patient data in environments where availability, integrity and confidentiality are equally critical.
Financial
services
Protecting sensitive information transmitted across long-distance and shared links, where interception risks increase.
