Postdoctoral Fellow in Quantum Information Theory and Fault-Tolerant Quantum Computation

Simula UiB (https://simula-uib.com) is a research institute in Cryptography and Information Theory located in Bergen, Norway. The Department of Information Theory is seeking an outstanding candidate for a postdoctoral researcher position in quantum information theory and fault-tolerant quantum computation, with a focus on logical operations for quantum low-density parity-check (qLDPC) codes. The position is part of the Research Council of Norway-funded project Noisy Intermediate-Scale Quantum Error Correction (NISQEC). The successful candidate will work under the supervision of Hsuan-Yin Lin and Eirik Rosnes.

How can logical quantum operations be implemented reliably with limited physical qubits and execution time? The postdoctoral researcher will address this question by developing fault-tolerant protocols for logical gates and logical Pauli-product measurements (PPMs) in qLDPC codes. The research will connect protocol design, syndrome compilation, decoding, and performance analysis to improve reliability and reduce resource overhead.

A central focus will be quantum code surgery, including lattice surgery and algebraic surgery, as a framework for implementing logical measurements and gates under realistic hardware constraints. The work will investigate how protocol design, syndrome-extraction circuits, and decoding jointly determine the fault tolerance and efficiency of these operations.
