Abstract: 
​â¶Ä‹â¶Ä‹â¶Ä‹â¶Ä‹â¶Ä‹â¶Ä‹The accumulation of errors in quantum computers limits the execution of powerful algorithms. As a result, current devices require Quantum Error Correction (QEC) to operate reliably in the presence of noise — a paradigm known as Fault-Tolerant Quantum Computation (FTQC).In this talk, I will introduce the principles of QEC, explain why it is essential, and illustrate how it can be implemented in practice on a neutral-atom quantum computing platform. This is meant to give the audience an intuitive sense of what it means to run a fault-tolerant quantum algorithm on real hardware. If time permits, I will discuss some promising quantum low-density parity-check (qLDPC) code constructions and the new opportunities they may offer for scalable fault tolerance.By the end of the talk, participants should be familiar with key concepts such as encoding circuits, logical gate implementation, syndrome extraction, as well as the practical challenges involved in realising these techniques experimentally.
