Abstract:
Problems associated with quantum many-body systems are notoriously difficult to solve on conventional computers, even using modern parallel processing units. These problems cover a large class of systems in physics, chemistry, biology, and material science. Feynman envisioned an approach to solve them by using one quantum system as a platform for simulating another, a technique that now is referred to as quantum simulation. There are two main approaches to quantum simulation: digital and analog. Digital quantum simulation exploits the universality of a quantum computer to carry out the simulation, whereas an analog quantum simulation uses a specially engineered quantum system to carry out a specific class of simulations. Each of these approaches has its own pros and cons and I will clarify this in my talk. I will start my talk with an introduction on quantum simulation and addressing the question that why do we need them for more exact simulations. Then after an introduction on digital and analog quantum simulation, I will present my recent results on simulating dynamics of complex open quantum systems using superconducting circuits.
