Mitigating cross-talk errors in gate-based quantum computations

MdM Quantum Meeting

I will start by giving a brief overview of the current status of universal and non-universal quantum computing. I will then tell about a case study of simulating the BCS model on IBM quantum computers and the error-mitigation techniques used in it [1]. I will discuss the technique of crosstalk randomized compiling that allows one to simplify the structure of noise on a quantum computer, mitigate the noise in simulation results and quantify the amount of crosstalk.
