LuxQuanta Gets €8 Million in Series A Funding to Hasten the Global Rollout of Cybersecurity Solutions

A €8 million ($9.3 million USD) Series A fundraising round has been successfully closed by LuxQuanta, a trailblazing European deep tech startup that specializes in quantum cybersecurity. The goal of this significant investment is to secure vital communications in the quantum era by accelerating the mass market adoption and worldwide deployment of the company’s Continuous-Variable Quantum Key Distribution (CV-QKD) technology.

A&G was the primary or major investor in the investment round, which was led by Big Sur Ventures. The European Innovation Council (EIC) Fund, Wayra, and GMV are among the new strategic investors taking part in the round. Corning and GTD, two current shareholders, also extended their pledges. Soft finance, such as a €2.5 million ($2.9 million USD) grant given to LuxQuanta in March 2024 under the EIC Accelerator program, further supports the investment.

Transition to a Global Scale-up

This milestone funding transformed LuxQuanta from a promising company to a global scale-up. The money will be judiciously utilized to build its commercial, technical, and operational teams, increase flagship system manufacturing, and research and develop integrated photonics and quantum technologies. With a focus on new markets in Europe and beyond, LuxQuanta plans to accelerate its worldwide market expansion.

Integrated photonics is emphasized as a crucial technology for upcoming research and development, putting the business in a position to lower expenses and improve scalability in order to satisfy the expanding need for quantum-safe products worldwide.

The CEO of LuxQuanta, Vanesa Díaz, underlined the significance of the investment, saying that the money is a strong affirmation of their goal to protect international communications. She reaffirmed the business’s dedication to ensuring that quantum security is dependable and affordable for enterprises everywhere.

Telecommunications, government, data centers, financial institutions, critical infrastructure, industrial, and energy sectors are among the industries that LuxQuanta’s products are intended to serve.

Using CV-QKD to Counter the Quantum Threat

The growing threat of strong quantum computers, which could crack existing encryption systems with “harvest now, decrypt later” assaults, makes the need for quantum-safe alternatives urgent. Using the principles of quantum physics, LuxQuanta’s CV-QKD technology creates and disseminates very secure cryptographic keys that defend against present and potential attacks.

The second version of LuxQuanta‘s flagship product, NOVA LQ, was introduced in March 2025. The system’s primary characteristics, which are meant to blend in seamlessly with current optical networks, are:

Security: Uses the extensively examined Gaussian-modulated coherent-state (GMCS) CV-QKD protocol, which has been shown to be safe from collective assaults in situations with finite sizes.

Interoperability: Compatible with SKIP and ETSI GS QKD 014 interfaces for multi-vendor encryptor and key management system integration.

Scalability: Supporting P2P and P2MP topologies, it may minimize network expansion costs by half while maintaining security.

Performance: Operates up to 20 dB channel loss and provides a high secret key rate (>100 kbps at 4 dB loss, 1 kbps at 16 dB). Up to 100 km can be covered by the system during operation.

Investor Trust and Strategic Alliances

The investors emphasised LuxQuanta’s technology and well-established position:

LuxQuanta’s successful deployments and proven CV-QKD technology establish it as a leader in quantum cybersecurity, according to Big Sur Ventures, which referred to its emphasis on integrated photonics as a “game-changer.”

LuxQuanta’s solutions are particularly positioned to secure critical environments, in line with their focus on vital industries where security and dependability are crucial, according to the A&G Energy Transition Tech Fund.

Telefónica’s corporate venture capital division, Wayra, confirmed that the collaboration promotes industry change and fortifies Europe’s technological superiority in quantum communications.

According to GMV, LuxQuanta’s technology advances European innovation in quantum-safe cybersecurity and marks a milestone in communications security for the quantum era.

Europe’s quantum innovation leadership was supported by the EIC Fund’s trust in LuxQuanta to lead the global transformation to quantum-safe infrastructure.
