Quantum error correction compiler for novel quantum computing platform

Realistic quantum computers unavoidably suffer from physical imperfections, such as environmental influence and imprecise control. An imperfect quantum computer will introduce computational error, so quantum error correction (QEC) is necessary to improve information accuracy. Standard QEC assumes an implementing circuit that involves a typical set of logic gates. However, not all the standard gates can be implemented naturally in a physical platform.

In this project, we will develop a software compiler for QEC in hybrid qubit-bosonic platform. This platform has the advantage that the generation of entanglement (the resource of quantum computing advantage) can be extremely efficient. However, the practical limitations of bosonic system, e.g. energy constraint, will introduce error. This GRA project is a part of the intern’s thesis, which characterizes the logical error during quantum computation. A compiler is a tool for the automated generation of optimal combinations of platform-specific gates that increase computational accuracy. With the compiler, we can explore the accuracy threshold, which will benchmark and guide the development of the platform.
