Make uncertainty
observable.
Compose a small quantum circuit. Watch amplitudes become measurable outcomes. Keep every experiment reproducible.

Every operation here runs in your browser. Select a gate, then place it on a wire. A two-qubit gate takes a control and a target.
Bell pair
Observe the difference.
Pin one run, edit the circuit or sampling setup, and run again. Differences between sampled distributions are quantified here.
A reference waits to be pinned.
Use “Pin as baseline” above, make a change, then run again to compare your observations.
Two observations reveal a pattern.
Leave a trace.
Records stay in this browser until you export them. Reopen a record to restore its circuit, seed and shot count, then reproduce the same sample.
Make provenance portable.
Future wallet signatures and on-chain digests could anchor experiment versions. This browser demo writes nothing to a blockchain.
What this instrument
actually measures.
This is an independent, small statevector simulator written for Phasefolio. It supports three qubits and H, X, Z, S and CX gates. Every run computes exact basis probabilities, then draws seeded pseudorandom samples. It does not call Qiskit, remote hardware, or a live network.
The workflow is inspired by Qiskit, an open-source SDK for circuits, operators, transpilation and primitives under the Apache 2.0 license. No Qiskit code or branding is included here. Results are illustrative simulations, not hardware measurements.
