QubitCoin (QTC) mining pools compared

· HeroMiners · Coins · 6 min read

The HeroMiners mascot, an orange robot with a gold crown, stands beside a comparison board under the QubitCoin logo, where the first column is all green ticks and the others mix yellow and red marks.

QubitCoin (QTC) is a proof of work coin built on Bitcoin Core. It is mined on graphics cards with an algorithm called qhash. This guide covers how its mining works, how the pools compare and how to start.

Quantus also uses the ticker QTC, but it is a different coin with its own chain, wallet and algorithm. So check the coin name as well as the ticker when you pick a pool or an exchange.

QubitCoin mining in short

  • QubitCoin is mined on NVIDIA, AMD and Intel GPUs. No ASIC, FPGA or CPU miner exists for the current hash.
  • Run SRBMiner-Multi 3.1.6 or later, WildRig NG or ForgeMiner.
  • Blocks come every 10 minutes and pay 50 QTC, with halvings like Bitcoin.
  • HeroMiners charges 1% for pool and solo mining and pays every hour from 0.1 QTC.
  • HeroMiners was the only pool in our comparison that could pay QubitCoin mining in Monero.

What a qhash share actually computes

QubitCoin keeps SHA-256 at both ends and puts a small quantum circuit simulation in the middle. Here is what your miner does on every attempt:

  • It hashes the 80-byte block header with SHA-256.
  • It splits the 32-byte result into 64 pieces of four bits. These set the rotation angles of 16 simulated qubits.
  • It runs two layers of the circuit. Each qubit is turned twice, then a chain of CNOT gates links each qubit to its neighbour.
  • It reads one number per qubit and rounds it to a fixed-point value.
  • It hashes the first result again together with those 16 values. This final hash is checked against the share and block targets.
How a qhash proof of work is computed: the block header is hashed with SHA-256, the result sets the rotation angles of a simulated 16-qubit circuit with two layers of gates and a chain of CNOTs between neighbouring qubits, every qubit is measured, and the first hash is hashed again together with those measurements to give the value checked against the block target.
The qhash pipeline: SHA-256, a 16-qubit circuit, its measurements, then SHA-256 again.

Two more rules apply. A result with too many zero bytes in its measurements is invalid, a rule added in mid 2025. On 25 September 2025 the angle formula changed slightly, so miners had to update that day. If an old miner build is rejected, this is usually why.

What hardware mines QubitCoin

Simulating 16 qubits means tracking 65,536 complex numbers for every hash attempt. That kind of parallel maths suits a GPU. To compare cards, see our best mining GPUs.

Every qhash attempt simulates 16 qubits at once, the kind of parallel maths a GPU is built for.

Three miners cover the common cards: SRBMiner-Multi (1.5% dev fee, version 3.1.6 or later), WildRig NG (2%) and ForgeMiner (1%, NVIDIA and AMD).

The chain in numbers

  • Block target: one block every 10 minutes, about 144 a day.
  • Block reward: 50 QTC plus fees, with no developer cut.
  • Halving: every 210,000 blocks, so the first comes at block 210,000.
  • Maximum supply: 21 million QTC.
  • Maturity: 100 confirmations, about 17 hours at the target pace.
  • Genesis block: 28 October 2024.
  • Addresses: Bitcoin's formats, starting with bc1, 1 or 3.

How HeroMiners compares on QubitCoin

We compare HeroMiners with the same five large pools on every coin we run. Only two of them mined QubitCoin on the check date, so the table has three pool columns. Green means the pool has the feature, yellow means part of it, and red means its page did not show it.

Every cell was checked on that pool's own site or API on 5 November 2026. A pool that offered email alerts alone, or none, is marked red for alerts.

How to choose a QubitCoin pool

  • Think about variance first. The network finds about 144 blocks a day, so a small pool may wait many hours between blocks. A larger pool smooths your earnings.
  • Solo keeps the whole 50 QTC block for the finder. It suits a big farm that likes the odds.
  • Compare the minimum payout with what your rigs earn. A threshold you reach in a day beats one you reach in a month.
  • Pick a server close to your rigs, since a lower ping means fewer stale shares. Check that the pool lists your miner, and whether it needs an account.

What HeroMiners offers on QubitCoin

One feature was on no other pool's QubitCoin page on the check date: payment in another coin. You can mine QubitCoin and be paid in Monero (XMR).

The pool converts your QTC on an exchange and sends XMR to your own address once a day, from 0.1 XMR. Exchange and network fees apply, so plain QTC stays the cheapest choice.

The wallet step of the HeroMiners QubitCoin how-to-mine guide: two payout cards, Qubitcoin (QTC) paid directly to your own wallet with a 0.1 QTC minimum, and Monero (XMR) where the pool converts your QTC on an exchange and pays XMR once a day from a 0.1 XMR minimum, above the address and worker name fields.

The rest, as checked on 4 November 2026: the fee was 1% for pool and solo mining, with PROP rewards. QTC payouts run every hour from 0.1 QTC, and you can raise your own threshold.

There are 11 server regions, each with its own proxy. Port 1195 takes both plain TCP and TLS. For solo, put solo: in front of your address and keep the whole block.

Alerts for blocks, payouts, hashrate drops and offline workers can go to Discord, Telegram, Web Push or ntfy. The site is in 37 languages, with a help centre and calculators. The fee can change, so check the live figure on the site.

Questions miners ask

Is QubitCoin the same coin as Quantus?

No. Both use the ticker QTC, but QubitCoin is a Bitcoin Core fork mined with qhash on GPUs, and Quantus is a separate chain with its own algorithm. A wallet for one cannot receive the other, so check the coin name.

Can I mine QubitCoin with a CPU?

Not in practice. The miners that run the current qhash rules are GPU miners for NVIDIA, AMD and Intel cards.

Can I use a Bitcoin wallet address?

Only if it comes from a QubitCoin wallet. The address formats are the same, so a Bitcoin address will be accepted and paid in QTC on the QubitCoin chain, where your Bitcoin wallet does not look.
