Toric Code Performance on a Neutral Atom Platform

Location: Eindhoven, the Netherlands Contact person: Dr. Rianne S. Lous Group website: www.tue.nl/rydbergQC

Description: Fault tolerant quantum computers are a stringent necessity for algorithms beyond the NISQ era. Quantum error correction allows for so-called logical qubits to be constructed from an ensemble of physical error-prone qubits. Such logical qubits have a lower error rate than its physical constituents. One promising way of encoding two logical qubits on a 2D array of neutral atoms is the toric code: a topological stabilizer code with the effective topology of a 2-torus. In this project, you will characterize the performance of the toric code on a neutral atom quantum computer. You are to identify the errors that arise in the system, such as radiative decay or coupling to motional states, characterize how well error corrections works for our system parameters, and compare to other codes or decoders. Eventually, this will lead to error-corrected operations such as the logical Hadamard and the logical CNOT that entangles the two logical qubits on the torus.

Prerequisite knowledge: quantum computing theory, atomic physics, preferably background knowledge on quantum error correction
