Questions Every Leader Should Be Asking

  • What is quantum computing, and when will it materially affect my organization?
  • What is post-quantum cryptography (PQC), and why does it matter now?
  • What do I need to know about Harvest Now, Decrypt Later (HNDL)?
  • How will these disruptive technologies impact my security posture, data longevity, and competitive position?

Our Vision

QSI strives to be the most trusted guide orchestrating leading experts to help governments and enterprises safely and discreetly navigate the quantum era.

Our Mission

We help federal, public, and private-sector leaders prepare for the quantum era by orchestrating trusted experts, translating complex quantum and post-quantum cryptography risks into clear strategy, and guiding practical, secure implementation grounded in decades of proven IT and cybersecurity leadership.

About QSI

QSI is a boutique consulting firm focused on helping governments and enterprises prepare for the quantum era. We guide leaders through the risks and opportunities of quantum computing and post-quantum cryptography (PQC) by orchestrating trusted experts and translating complex technologies into clear strategy and practical action, informed by decades of global IT and cybersecurity experience.

Why Quantum Matters

Leading scientific and government institutions recognize the transformative impact of quantum technologies.

“We expect quantum technology to change and improve the way we do secure communication and information processing, improve sensitivity of detectors and sensors, provide new functional materials for future electronic devices and change the way we approach computing.”

“The threat to cryptography from future large-scale, fault-tolerant quantum computers is now well understood…Quantum computers will be able to efficiently solve the hard mathematical problems that asymmetric public key cryptography (PKC) relies on to protect our networks today.”

What We Do
