In this episode, Mira and Chris talk with Markus Müller, a member of ML4Q and Professor at RWTH Aachen University and Forschungszentrum Jülich. Markus, an expert in quantum error correction, explains its importance in building large-scale quantum computers. He has supported pioneering logical qubit experiments on various platforms, including ion traps and superconducting qubits. They also discuss his recent work on avoiding mid-circuit measurements, a technique that benefits certain architectures and chip designs.

00:00:00 Intro
00:01:06 Welcome Markus
00:01:35 Reflections on the early career experience
00:21:44 A deep dive into quantum error correction
00:44:02 Getting to the promised land of fault-tolerant quantum computing
00:50:20 About magic state preparation and injection
00:55:23 About code switching
00:57:23 What about decoding?
01:01:15 Discussing recent work on fault-tolerant resource optimized schemes
01:12:02 Outlook on future projects
Note: The episode was recorded back in March. The recent work discussed from 01:01:15 onwards is the paper titled “Measurement-Free Fault-Tolerant Quantum Error Correction in Near-Term Devices” a synopsis of which appeared on physics.org. Since the recording another work on the “Demonstration of fault-tolerant Steane quantum error correction” was published in PRX Quantum.
