## What is Quantum Edge?

Quantum Edge runs real quantum circuit simulations directly on your device using
Apple's Metal GPU framework — no cloud compute, no vendor lock-in, no abstractions hiding the physics.
Built for practitioners who want to understand quantum computing from the hardware up.

WHAT'S INSIDE

  QPO — Quantum Prompt Optimisation
  Watch a QAOA (Quantum Approximate Optimisation Algorithm) circuit run gate-by-gate
  on your device. Four Bloch spheres update in real time via reduced density matrix.
  On Apple Intelligence devices, enter any goal and the on-device language model
  decomposes it into binary feature axes, scores all candidate variants, builds a QUBO
   matrix, and runs the quantum circuit to find the optimal prompt configuration.
  
  Bloch Sphere
  Interactive single-qubit visualisation. Apply gates and watch the
  state vector move in real time. Rotate freely, reset on demand.

  Gate Sequencer
  Build two-qubit circuits interactively. Drag gates onto a circuit diagram and see
  the statevector evolve.

  Entanglement
  Bell state and GHZ state visualisations with animated probability arcs. See
  entanglement happen.

  Benchmark
  Three honest benchmark modes:
  • Sweep n=4–20: wall-clock time per gate across qubit counts
  • Find Ceiling: push from n=20 until jetsam kills the process — find your device's
  exact memory wall
  • Depth n×d: n=20–30 × depth 1–4, measures Metal bandwidth saturation
