Joschka Roffe

Dr. Joschka Roffe is an EPSRC Quantum Career Acceleration Fellow at the University of Edinburgh and serves as the Quantum Error Correction Lead and Board Member at the UK's Quantum Software Lab. His research focuses on developing quantum error correction protocols to enable fault-tolerant quantum computing, addressing the fundamental challenge of qubit fragility in quantum systems.

Dr. Roffe's educational background includes:

• MPhys Physics from Manchester University (2011-2015)
• A year abroad at the University of California, Santa Barbara (2013-2014)
• PhD in Quantum Computing from Durham University (2015-2018)
• Research Associate at Sheffield University (2018-2021)
• Postdoctoral Researcher at Freie Universität Berlin (2021-2023)

Dr. Roffe's research addresses the critical challenge that quantum bits (qubits) are realized through fragile quantum systems such as single ions, photons or superconducting circuits, making them highly susceptible to errors. His work develops quantum error correction protocols designed to mitigate these errors, which is essential for realizing practical quantum computers that can outperform classical systems. His expertise spans theoretical frameworks for quantum error correction to practical implementations that could enable scalable quantum computing architectures.

His publication record shows a clear progression from foundational work on the Coherent Parity Check framework during his PhD to increasingly sophisticated approaches for quantum LDPC codes, surface codes, and fault-tolerant architectures. Notably, his 2019 review paper 'Quantum error correction: an introductory guide' published in Contemporary Physics has become a standard reference in the field.

His notable scientific achievement is the prestigious EPSRC Quantum Career Acceleration Fellowship, which supports his research at the University of Edinburgh.

Dr. Roffe leads the quantum error correction efforts at the Quantum Software Lab, where he collaborates with researchers across the UK to advance quantum software development. His work bridges theoretical quantum information science with practical implementations that could enable the next generation of quantum computers capable of solving problems beyond the reach of classical computing.
