📡 GHZ on Real Quantum Devices
Play the GHZ Game on noisy copies of IBM quantum computers — and win back most of the rounds the noise costs you.

git clone the repository, create the conda environment from environment.yml, and open GHZ-on-Real-Devices.ipynb.Simulators are perfect; real quantum computers are not. This notebook plays the GHZ Game on simulated copies of six IBM quantum computers — fake backends that add the noise measured in a calibration snapshot of each device — and confronts the noise head-on: gate errors, readout errors, and what the transpiler does to your circuit before it reaches the chip.
On bad qubits the quantum team barely beats a classical one — or falls to guessing. You’ll pick better qubits by hand and with the transpiler, then correct the readout errors with readout error mitigation to win back most of the lost rounds. An appendix runs the same experiment on a real IBM quantum computer (free IBM Quantum Platform account). A realistic first encounter with the craft of making today’s noisy devices useful.
