Statevector

The Statevector panel shows your circuit's quantum state as both a bar chart of amplitudes and the raw statevector array:

Statevector panel

  • The bar chart plots amplitude magnitude against each computational basis state; bar color reflects phase
  • Below the chart, the full statevector is printed as an array of amplitude values (e.g. [0.707, 0, 0, 0.707, 0, ...]), with a copy icon to copy it directly
  • The small Phase color wheel (bottom left) shows the same phase-to-color mapping used in the Q-Sphere

Info

Click the ⓘ icon (top-right of the panel) to see an explanation of what the chart shows:

Statevector info tooltip

Complex amplitudes ⟨x|ψ⟩ for each computational basis state after running the circuit. Bar height shows magnitude, bar color shows phase. Switch to table view for exact real/imaginary values.

Phase info

Bar color in the chart encodes phase, using the same Phase color wheel legend shown in the panel and in the Q-Sphere.

Vector info

The array below the chart is the exact statevector - each entry is one basis state's complex amplitude, in the same left-to-right order as the chart's basis states.

Table view

Click the table icon (top-right of the panel, next to info) to switch to an exact-value table, showing each basis state's amplitude as a full complex number (real + imaginary) alongside its phase angle:
