报告摘要：As nanotechnology progresses towards the atomic scale, quantum effects will become unavoidable. However, this is not always a nuisance. On the contrary, using quantum resources can make possible surprising improvements in the efficiency over its classical counterpart. For example, quantum information processors (QIPs) use the laws of quantum mechanics for computation, communication, and information storage. Spins feature prominently in most condensed matter proposals for QIPs, either directly being used as computational or storage qubits, or being important sources of decoherence.

In this talk, I will introduce the basics of spin-based quantum information processing by nuclear magnetic resonance, report our experimental progresses on quantum algorithms and quantum simulations, and discuss current, proposed roles and future directions for nuclear magnetic resonance-based QIP. In more details for our experiments, I will focus on solving the problem of integer factorization by quantum algorithms, and simulating exotic many-body quantum systems by quantum simulators. These experiments fully demonstrate the feasibility of small QIPs.
