QubitDecoded takes quantum computing from zero to Shor's algorithm — with browser-based simulators, rigorous math, and zero paywalls. Every lesson on this site is free, and we intend to keep it that way. This page explains what it actually costs to build and maintain this, and how you can help if you want to.
Most quantum computing resources fall into one of two traps: either they're watered-down pop-science that never gets to real math, or they're dense academic papers that assume you already work in the field. QubitDecoded is built to be neither.
Every lesson follows a fixed structure — intuition first, then a conceptual framework, then formal theory, then the full mathematics, then an interactive you can actually play with. The circuit simulator runs a complete state-vector simulation in your browser. The Bloch sphere renderer is built from scratch. Nothing here is a wrapper around a third-party widget.
This is research-quality content made free, and keeping it that way is a deliberate choice — one that costs real time and real money.
No vague promises. Here is exactly what support funds:
There's no tier that's "too small" and no tier that unlocks special treatment — everything stays free for everyone regardless. Pick whatever feels appropriate for the value you've gotten.
Quantum education is the kind of thing that should exist on the internet for free. The physics is not secret. The math is not proprietary. The only reason good courses don't stay free is that building them well costs time, and time costs money.
QubitDecoded exists to fix that. If you agree it should exist, supporting it is a direct vote for the kind of web you want.
— Team QubitDecodedSecure checkout options — including card and bank transfer — will appear in the section below once our payment backend is live. These buttons scroll directly there.
One-time and recurring payment options will live here — card, bank transfer, and any regional methods we can offer with low fees. We'll keep the process straightforward, send you a receipt, and never reference your contribution again in lessons or prompts.
Until the payment backend is connected, you can reach us directly via the About page if you'd like to contribute now.
Payment integration — coming soonIf donating isn't the right move right now, these alternatives have a real impact on the project's reach and quality:
No guilt if you leave this page empty-handed. Come back when a lesson genuinely changes how you think about something — that's a better reason to support it than obligation.
