Qiskit - Real Hardware & Pulse Control

Moving from simulators to real hardware requires a shift in mindset. You are no longer working with perfect "ideal" qubits, but with superconducting circuits that suffer from decoherence, readout errors, and crosstalk. This guide covers how to get the most science out of noisy intermediate-scale quantum (NISQ) devices.

When to Use

• Executing quantum algorithms on real IBM Quantum backends.
• Characterizing hardware noise (T1, T2 relaxation times).
• Implementing Error Mitigation to improve result accuracy.
• Using Qiskit Pulse to define custom microwave pulses (OpenPulse).
• Optimizing circuits for specific hardware topologies (coupling maps).
• Benchmarking quantum advantage in real-world conditions.
