What is Qubitcoin?
Imagine Bitcoin, but the “work” your computer does while mining actually means something.
Qubitcoin (QTC) is a cryptocurrency built on a fork of Bitcoin Core. It keeps the parts people trust, 21 million coin cap, halving every 210,000 blocks, proof-of-work security, but replaces the mining puzzle with something new: Quantum Proof of Work (qPoW).
The one-liner: Your GPU pretends to be a tiny quantum computer. That simulation secures the blockchain and helps advance quantum science, while you earn QTC.
Traditional Bitcoin mining burns electricity solving random math puzzles that get thrown away. Qubitcoin miners run 16-qubit quantum circuit simulations on NVIDIA GPUs. The results are turned into a hash that secures the network, and every simulation contributes to benchmarking quantum computing hardware.
Qubitcoin is maintained by Superquantum, a non-profit focused on merging blockchain incentives with quantum research.
Bitcoin vs Qubitcoin
Same scarcity model. Different kind of work.
| Bitcoin | Qubitcoin | |
|---|---|---|
| Max supply | 21,000,000 | 21,000,000 |
| Halving schedule | Every 210,000 blocks | Every 210,000 blocks |
| Starting block reward | 50 BTC | 50 QTC |
| Proof of work | SHA-256 hash puzzles | 16-qubit quantum circuit simulation (QHash) |
| Work output | No useful computation | Advances quantum simulation benchmarking |
| Best mining hardware | ASIC miners | NVIDIA GPUs (cuQuantum) |
