Noisy Intermediate Scale Quantum Computers: on the Co-Simulation of Qubits and Control Electronics

In this paper, we discuss the challenges in modeling of Noisy Intermediate Scale Quantum Computers, in particular, those implementations that rely on integrated interface and control electronics. We begin with an overview of the current state of quantum computers and highlight the emergence of quantum engineering and its relation to electrical and electronic engineering. We then discuss qubit modeling and existing solutions. The particular example we focus on in this paper is related to semiconductor CMOS charge qubits. For this reason, we overview the physical models and equivalent circuit model of this type of qubits.
