What is Q-Day and why is it a threat?

Q-Day refers to the point at which quantum computers can break classical encryption (RSA, ECC), exposing sensitive banking, healthcare, and defense data.

How will Q-Day impact banking and financial systems?

Q-Day could compromise billions in transactions daily by breaking TLS certificates, VPNs, and digital signatures critical to banking security.

What industries are most at risk from Q-Day?

Industries most exposed include banking, healthcare, defense, and AI-driven platforms that rely on public key infrastructure and digital trust.

What is post-quantum cryptography?

Post-quantum cryptography (PQC) involves new encryption algorithms designed to resist attacks from large-scale quantum computers.

What strategies should enterprises adopt for quantum readiness?

Enterprises should begin inventorying cryptographic assets, adopting hybrid encryption, and engaging startups building quantum-resistant solutions.

How does Q-Day compare to Y2K?

Unlike Y2K's fixed date bug, Q-Day has uncertain timing but far greater systemic risk, potentially costing trillions if unaddressed.

Q-Day Industry Report 2025 | Pitchworks VC Studio

The Q-Day Industry Report 2025 by Pitchworks VC Studio explores the looming quantum threat that could transform the foundations of cybersecurity, encryption, and digital infrastructure worldwide.

What is Q-Day in Cybersecurity?

Q-Day marks the moment when quantum computing becomes powerful enough to break traditional encryption methods like RSA and ECC. Experts warn that this will trigger massive risks across banking security, healthcare data, and defense systems security.

How Will Quantum Computers Break Encryption?

Quantum algorithms like Shor’s make today’s digital locks obsolete. This means:

Quantum threat to banking transactions
Quantum risk to healthcare records
Exposure of classified defense information
A trillion-dollar risk to the global economy
