Empower decision-makers to understand emerging risks, share best practices, and accelerate organizational readiness for the quantum era.

The rise of quantum computing represents a major shift for global cybersecurity. Current digital systems rely heavily on cryptographic mechanisms that could eventually become vulnerable to the processing power of quantum computers.
Organizations must therefore begin preparing today for their transition to a new generation of digital security: Quantum-Safe Cybersecurity.
Q-Day Finance™ is an executive event dedicated to the challenges of Quantum Cybersecurity, Post-Quantum Cryptography, and Quantum-Safe Communication within the financial sector.
Empower decision-makers to understand emerging risks, share best practices, and accelerate organizational readiness for the quantum era.





The quantum threat isn't waiting for tomorrow. Neither is the financial sector.
The "Harvest Now, Decrypt Later" paradigm is no longer a theoretical concept: it is an immediate operational risk threatening banking infrastructure, capital markets, and the confidentiality of financial data.
Combined with the rise of cyberattacks driven by autonomous and agentic AI systems, the technological status quo exposes international finance to critical vulnerabilities. Q-Day Finance™, co-organized by the teams behind the Q-Day Summit™ and the Luxembourg Quantum Alliance, stands as the essential executive summit for the end of this year.
Key themes of the preliminary program (program currently under development, subject to change):
Q-Day Finance™ is organized by the Luxembourg Quantum Alliance (LQA) in partnership with Q-Day Summit™, the leading French platform dedicated to the strategic challenges of quantum security and post-quantum communications.

Following the success of the first French edition of Q-Day Summit™, which brought together over 200 decision-makers and a dozen major partners, Q-Day Summit™ is preparing its second edition in France for June 2027, as well as Q-Day Series in Germany (2026) and Switzerland (2027).
Establishing Luxembourg as a premier European hub for the Quantum Cybersecurity Transition in the Financial Industry.
