No jargon. No PhD required. A clear explanation of what quantum computing means for your organisation — and what you can do about it today.
When you send a message, process a payment, or store customer data, your systems scramble the information using a mathematical problem that is practically impossible to solve. This scrambling is encryption.
The problems used today — factoring enormous prime numbers — would take a classical computer millions of years to crack. That is why banks, hospitals, governments, and virtually every business on earth trust them.
Your business has a padlock that takes a million years to pick. So far, no thief has been patient enough. But a new kind of thief is arriving — one who can pick it in minutes.
Classical computers think in 0s and 1s, solving one answer at a time. Quantum computers use the laws of quantum physics to explore millions of possibilities simultaneously. For the specific mathematical problems your encryption depends on, this makes them extraordinarily fast.
A quantum computer running an algorithm called Shor's Algorithm can crack RSA and ECDSA — the two most common encryption types used by Indian businesses — in minutes, not millions of years.
Google's Willow chip (December 2024) crossed a key engineering threshold. IonQ Chairman and CEO Niccolò de Masi, speaking at the World Economic Forum, Davos, January 2026: "There is a geopolitical race underway to see who cracks encryption first... we believe IonQ will be first." He compared the race to build fault-tolerant quantum computers to "the Manhattan Project of our era."
Q-Day is the point when quantum computers become powerful enough to break current encryption. Estimates range from 3 to 10 years. But you do not need to wait for Q-Day to be at risk — the threat is already active today.
Intelligence agencies and sophisticated threat actors are currently collecting your encrypted data — transactions, customer records, communications — and storing it. They cannot read it yet. They are betting they will be able to once quantum computers arrive.
This is called Harvest Now, Decrypt Later (HNDL). It is not a future threat. It is active today.
For Indian financial entities, RBI's 7-year data retention mandate means records encrypted in 2024 remain in scope until 2031 — well within every Q-Day estimate. Your oldest data is your highest-risk data.
₹84,000+ crore in daily UPI transactions are at cryptographic risk (NPCI, May 2026). Every transaction settled today using RSA or ECDSA is a potential future liability under HNDL attacks.
Post-quantum cryptography (PQC) refers to a new generation of encryption algorithms designed to resist quantum computer attacks. These are not quantum computers themselves — they are new mathematical approaches that even quantum computers cannot crack efficiently.
In August 2024, NIST officially published the world's first post-quantum encryption standards:
Migrating from RSA and ECDSA to these algorithms is the technical core of becoming quantum-safe. SEBI's CSCRF framework, RBI's Q-SAFE mandate, and India's DST roadmap all require this migration.
On May 25, 2026, the Reserve Bank of India constituted the Quantum Secure and Adaptive Financial Ecosystem (Q-SAFE) expert committee — India's most significant regulatory response to quantum risk so far.
The Q-SAFE committee is mandated to evaluate every financial institution's cryptographic systems through a Cryptographic Bill of Materials (CBOM), identify the most vulnerable systems, assess crypto agility, and recommend a national migration roadmap.
The committee report is due within six months of its first meeting (formed 25 May 2026) — commonly estimated around November 2026, though this is an estimate, not a confirmed date. Every bank, NBFC, fintech, and payment company in India will need to respond.
Don't wait for the report to publish. SEBI's CSCRF audit and PQC-readiness obligations are already live today, independent of the Q-SAFE timeline — entities that begin assessment now have a genuine head start.
A Cryptographic Bill of Materials (CBOM) is a complete inventory of every cryptographic algorithm, key, certificate, and library your organisation uses. Think of it as a fire safety register — but for encryption.
Just as a building must list every fire extinguisher, exit, and sprinkler for a fire safety audit — your organisation must list every piece of encryption for a quantum security audit. Without the list, you cannot know what needs replacing.
RBI's Q-SAFE committee has made CBOM generation a regulatory expectation. SEBI's CSCRF framework requires it for all regulated entities. QryptoNox creates your CBOM as part of every assessment — in the format regulators expect.
This is the most common misconception we encounter. The answer: partially, and not the parts that matter most.
AWS describes this as a "shared responsibility model" — they handle their layer, you handle yours. SEBI requires your CBOM and your risk assessment, not AWS's compliance whitepaper. The 70% of your attack surface that sits in your application layer remains entirely your responsibility.
QryptoNox gives you a complete quantum risk picture — in plain rupees, with a clear plan, formatted for your board and your auditor.
