M.S. Paper Title: Resource Optimized Quantum Architectures for Surface
Code Implementations of Magic-State Distillation

Abstract:
Quantum computers capable of solving classically intractable problems
are under construction, and intermediate-scale devices are approaching
completion. Current efforts to design large-scale devices require
allocating immense resources to error correction, with the majority
being dedicated to the production of high-fidelity ancillary states
known as magic-states. Leading techniques focus on dedicating a large,
contiguous region of the processor as a single "magic-state
distillation factory" responsible for meeting the magic-state demands
of applications.

In this work we present a comprehensive analysis of the realistic
resource requirements of factories, along with optimized architectural
layouts that divide a single factory into spatially distributed
factories located throughout the processor. We find the distributed
factory architectures minimize the space-time volume overhead imposed
by state distillation, and the granularity of optimal configurations
is sensitive to application characteristics and underlying physical
device error rates. Our techniques yield between a 10x and 20x
resource reduction compared to commonly accepted single factory
designs, when applied to representative application classes such as
quantum simulation and quantum chemistry.

Yongshan's advisor is Prof. Frederic Chong
