Quantum Computing: Quantum Error Correction in Bosonic Qubits

(28:35 + Q&A) Marina Kudra, PhD, Intermodulation Products -- Presentation from 2023 Workshop on Quantum Computing: Devices, Cryogenic Electronics and Packaging (QC-DCEP) ...
Summary: Quantum error correction (QEC) is an essential ingredient of quantum computers. It is an algorithm that lowers the rate of physical qubit errors by redundantly encoding binary quantum information in a multidimensional quantum system. I explain on a high level what quantum error correction is and give an overview of quantum error correction protocols implemented so far in superconducting circuits. To date, bosonic qubits stand out as the only system that improved qubits’ lifetime by implementing QEC. So we will look into the advantages of bosonic error correction schemes. Finally, I will summarize the challenges we encountered when we implemented parts of the autonomous QEC protocol in a bosonic mode.
Marina Kudra, PhD, works for Intermodulation Products as Quantum Application Specialist helping customers implement their experiments using IMP products. She recently completed her PhD at Chalmers University of Technology in Sweden with the topic Building a Bosonic Microwave Qubit. Her PhD work covered everything from building hardware components of bosonic qubits up to designing a quantum error correction protocol. She did a EMM Nanoscience and Nanotechnology master jointly at KU Leuven in Belgium and Chalmers University of Technology in Sweden. She did a Bachelor program in Electrical Engineering at Belgrade University in Serbia.
