About Eigen State
Strategic consultancy at the intersection of quantum computing, artificial intelligence, and business strategy.
The Name
An eigenstate is a fundamental concept in quantum mechanics—a definite, measurable state of a quantum system. In German, eigen means "characteristic" or "own."
Just as eigenstates provide clarity in quantum systems, we help organisations find clear, actionable strategies amid the complexity of emerging computational technologies.
What We Do
We help organisations answer three critical questions:
Where is quantum computing relevant?
Most quantum opportunities are not obvious. We identify high-value problems where quantum approaches offer genuine advantages.
How should you prepare?
Quantum computers will break current encryption. They will also solve previously intractable problems. We help you prepare for both.
What AI creates real value?
Beyond the hype, which AI applications solve actual problems? We focus on implementations with measurable ROI.
The Quantum Threat Landscape
SNDL Attacks
Store Now, Decrypt Later attacks are happening today. Adversaries harvest encrypted data now, storing it until quantum computers can break current encryption. Any sensitive data with long-term value is already at risk.
PQC Transition
Post-Quantum Cryptography migration is no longer optional. NIST published quantum-resistant standards in 2024. Organizations face a 5-10 year migration timeline. RSA-2048 break projected by 2030-2035.
Y2Q Problem
Year to Quantum parallels Y2K but with higher stakes. Unlike Y2K's known deadline, quantum arrival is uncertain. Organizations that delay risk catastrophic security failures.
PQC Migration Timeline
Key milestones in the transition to quantum-resistant cryptography:
NIST PQC Competition Launched
NIST initiates standardization process for quantum-resistant algorithms
Algorithm Selection
NIST announces first four algorithms for standardization
NIST Standards Published
Final PQC standards released: ML-KEM, ML-DSA, SLH-DSA

Frequently Asked Questions
01 What is post-quantum cryptography?
Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to be secure against attacks from both classical and quantum computers. NIST standardized several PQC algorithms in 2024, and organizations need to migrate their infrastructure to these new algorithms before large-scale quantum computers become available.
02 What are SNDL attacks?
Store Now, Decrypt Later (SNDL) attacks involve adversaries harvesting encrypted data today, storing it until quantum computers become powerful enough to break current encryption (RSA, ECC). Any sensitive data with long-term value—financial records, health information, intellectual property—is already at risk.
03 When will quantum computers break current encryption?
Quantum computers capable of breaking RSA-2048 are projected to emerge between 2030-2035. However, the exact timeline is uncertain, which is why organizations should begin PQC migration planning now to avoid catastrophic security failures when quantum computers mature.
04 What is quantum advantage?
Quantum advantage is the point at which a quantum computer solves a practical problem faster or more efficiently than the best known classical approach. Genuine quantum advantage is expected in optimization, molecular simulation, and certain machine learning tasks.
05 How long does PQC migration take?
Organizations typically face a 5-10 year migration timeline to implement quantum-resistant algorithms across their infrastructure. This includes cryptographic inventory, risk assessment, algorithm selection, testing, and phased deployment.
06 What NIST PQC algorithms should we implement?
NIST standardized ML-KEM (formerly CRYSTALS-Kyber) for key encapsulation and ML-DSA (formerly CRYSTALS-Dilithium) for digital signatures. SLH-DSA (SPHINCS+) provides a hash-based alternative. Organizations should prioritize hybrid approaches combining classical and PQC algorithms during transition.
07 Which industries are most at risk from quantum threats?
Financial services, healthcare, government, and critical infrastructure face the highest risk due to long data retention requirements and regulatory obligations. Any organization handling data that must remain confidential for 10+ years should begin PQC planning immediately.
08 What is crypto-agility and why does it matter?
Crypto-agility is the ability to rapidly switch cryptographic algorithms without major system changes. It's essential for PQC migration because algorithm recommendations may evolve, and organizations need flexibility to respond to new threats or vulnerabilities.
