Abstract:
Quantum error correction is a critical technique for transitioning from noisy intermediate-scale quantum (NISQ) devices to fully functioning quantum computers. The choice of error correction code will influence the full quantum computing stack, from the layout of qubits at the physical level to gate compilation strategies at the software level. The surface code, which has a high threshold error rate, is the leading quantum error correction code for two-dimensional grid architecture. In addition, bosonic also called an oscillator or a continuous-variable (CV) code is also a recently reported alternate option. Encodes logical Hilbert space, finite- or infinite-dimensional, into a physical Hilbert space that contains at least one oscillator. Bosonic quantum error correction is a viable option for realizing error-corrected quantum information processing in continuous-variable bosonic systems. I will outline the construction and operation of the surface code, the most widely pursued error correction protocol for experiment. I will discuss issues that arise in the practical implementation of the surface code and other quantum error correction codes. Will discuss the recent progress of different bosonic codes and summarize the challenges associated with the bosonic codes and potential research directions.

Bio:

Saleem Rao is an Associate Professor of Physics at KFUPM. In 2005, he received his Ph.D. in Physics (fabrication and characterization of CNT-based integrated circuits) from Florida State University. After completing his Ph.D., he served as faculty in the USA and in Pakistan, and in 2009 he joined KFUPM as an Assistant Professor. His area of research is nanostructure-based integrated circuit fabrication and its characterization.  Since 2018, he is actively involved in superconducting quantum-chip fabrication and their low-temperature characterization in collaboration with UC Berkeley and KAUST.

All faculty, researchers, and students are invited to attend.
