Title: Innovations by David Sutter in Quantum Computing

Introduction

David Sutter is an accomplished inventor based in Zurich, Switzerland. He has made significant contributions to the field of quantum computing, holding two patents that focus on error mitigation techniques. His work is pivotal in advancing the capabilities of quantum devices.

Latest Patents

Sutter's latest patents include "Quantum error mitigation using hardware-friendly probabilistic error correction" and "Fault-tolerant T-gates via quasiprobability decomposition." The first patent outlines techniques that facilitate error mitigation for quantum computing devices. It describes a system that executes computer-executable components stored in memory, which include an approximation component, a budget component, and an optimization component. The approximation component generates an approximate decomposition of a quantum gate, while the budget component sets a budget value for a C-factor that measures the increase in variance of quasi-probability sampling. The optimization component determines an optimal decomposition for the quantum gate based on this budget.

The second patent focuses on simulating a fault-tolerant T-gate with low sampling overhead using the quasiprobability decomposition method. This innovation combines quantum error correction and quantum error mitigation techniques. In some embodiments, the T-gate is simulated using two logical bits and a magic state preparation, which reduces the need for magic state distillation, resulting in low sampling overhead. Additionally, noise is removed from the T-gate using quasiprobability decomposition based on a learned logical error rate.
