Error mitigation on Amazon Braket with program sets and Mitiq

This article explains how Amazon Braket's program sets enable quantum error mitigation using the Mitiq toolkit to improve quantum computational accuracy while reducing costs.

• Program sets allow multiple circuit variations to be submitted in single tasks, reducing execution time and costs
• 30-qubit error mitigation experiment achieved 12x error reduction with 86x cost reduction
• Readout error mitigation corrects output distribution using confusion matrix inversion or post-selection
• Zero-noise extrapolation models expectation values at multiple noise levels and extrapolates to zero-noise limit
• Pauli twirling transforms noisy quantum channels to standard form using randomized gate insertion
• Rigetti Ankaa-3 workflow combined REM, PT, and ZNE with 11x shot overhead
• New example notebooks available in Amazon Braket Examples repository demonstrating all techniques

Error mitigation with program sets enables practical improvements to noisy quantum computers by combining multiple techniques while substantially reducing computational costs.
