Research

Welcome!👋 Integrate circuits (ICs) are the infrascture of the information society as the core part of data processing (computing). 

In Liao lab, we mainly focus on the both of the current classical ICs (VLSIs) and the emerging techniques of the quantum ICs. 

Our research topics are featured with reliability, along with the more general topics such as the high-performance and low-power computating ICs.

Radiation is invisible but a very significant error source of ICs. During the designed lifetime of ICs, the radiation-induced soft errors are the dominant errors in ICs.

The error rate of soft error is different with different system/circuits/cells design. In our lab, we are making effort to evaluate and predict the soft error rate in the emerging devices with the simulation and the good accessibility to high-intensity beam.

Based on the evaluation above, we also design ICs designs to achive the strong tolerance to soft error in both embedded and HPC systems. Recently, soft errors in superconducting quantum ICs are reported, which also interest us a lot.

Quantum computing is a promising candidate in the post-silicon era. However, due to the large noise, the short lifetime of Qubit is the main obstacle for the quantum computing device.

FTQC is regarded as the complete solution for noise issue. We are trying to integrate the design of both quantum and classical parts to tackle several engineering challenges being necessary for FTQC.

On the other hand, we are also researching on the improvement of quantum algorithm, which is more efficient at FTQC.
