Grover’s Search Visualizer

A tiny Python package that steps through Grover’s Search algorithm and shows you, after each iteration:

• A bar‐chart of amplitudes (or probabilities)
• A sine‐curve of success‐probability vs. iteration
• A geometric "rotation" on the unit circle

Choose between a Matplotlib-based CLI or an optional DearPyGui GUI (WIP).

Installation

Via pipx

Basic (CLI only):

pipx install grovers-visualizer
grovers-visualizer 1111

With the optional DearPyGui UI (WIP):

pipx "grovers-visualizer[ui]"
grovers-visualizer --ui

Via uvx

Basic (CLI only):

uvx grovers-visualizer 1111

With the optional UI extra:

uvx "grovers-visualizer[ui]" --ui

Usage

CLI Mode

Flags:

• TARGET
   Target bit‐string (e.g. 010). Length determines number of qubits.
• -s, --speed SPEED
   Delay between iterations (seconds). Default 0.5.
• -i, --iterations ITERATIONS
   Max iterations; 0 means use the optimal \lfloor\frac\pi4\sqrt{2^n}\rfloor.
• -p, --phase PHASE
  The phase \psi (in radians) used for both the oracle and diffusion steps. Defaults to \pi (i.e. a sign-flip, e^{i\pi}=-1).
• --ui
   Launch the optional DearPyGui GUI (requires the [ui] extra) (WIP).

GUI Mode (WIP)

If you installed with "[ui]", launch the DearPyGui window:

grovers-visualizer --ui

In the UI you can:

• Set number of qubits
• Enter the target bit‐string
• Choose max iterations or leave at 0 for optimal
• Control the animation speed

Hit Start to watch the bar chart, sine plot, and rotation‐circle update in real time.
