Quantum Error Correction Modeling using the Intel® Quantum Software Development Kit (SDK)

A common use for quantum simulation is the evaluation and vetting of quantum error correction (QEC) protocols. In this talk, we provide an example of the use of the full-stack-in-simulation capabilities of the Intel Quantum SDK for this purpose. We start by demonstrating scaling simulations using a Clifford simulation backend to investigate the existence of an error threshold. Due to the hybrid design of the Intel Quantum SDK, we show how the classical decoding implementation can be written in C++ and seamlessly integrated with the quantum syndrome extraction circuit. We also demonstrate the simulation of smaller code instances with more realistic simulation modeling .This is done through tomography on a full-stack simulation to extract chi matrix representations of the gates. These chi matrices are then fed into the custom error modeling interface for the Intel Quantum Simulator state vector qubit backend to scale to code sizes of near-term interest.
