IQI Weekly Seminar

Abstract: Bosonic quantum error correction is a viable option for realizing error-corrected quantum information processing in continuous-variable bosonic systems. Various single-mode bosonic codes such as cat, binomial, and GKP codes have been implemented experimentally in circuit QED and trapped ion systems. Moreover, there have been many theoretical proposals to scale up such single-mode bosonic codes to realize large-scale fault-tolerant quantum computation. In this talk, I will present some of my results on single-mode bosonic codes. Furthermore, I will discuss concatenation of single-mode bosonic codes with conventional multi-qubit codes. In particular, I will consider the concatenation of the single-mode GKP code with the surface code and explain how the additional information gained from bosonic error correction can significantly boost the performance of the surface code. I will also briefly discuss various other applications of bosonic quantum error correction.
