What it calculates
The initial state is cos(θ/2)|0⟩ + e^(iφ)sin(θ/2)|1⟩. The selected 2×2 unitary is applied directly with complex arithmetic.
Working now Starter lab / QUBT
Forefront Qubit
Lab
Prepare a pure qubit on the Bloch sphere, apply one common gate and inspect the resulting amplitudes and measurement probabilities.
Working starter tool / v0.1
Single-qubit gate lab
Prepare a pure qubit on the Bloch sphere, apply one common gate and inspect the resulting amplitudes and measurement probabilities.
What it does not prove
This is an exact, noiseless single-qubit simulation. It does not model decoherence, sampling noise, calibration, multi-qubit entanglement or physical hardware.
Build on the mission
Use it, inspect it, prepare the next build.
Independent starter tool. This lab is functional software, but it is intentionally narrow and does not claim to complete the full Circuit Bridge roadmap. Every benchmark separates simulator results from physical-hardware results.
