Quantum error correction in trapped-ion motion
Home, Jonathan - ETH Zurich
Presentation on Thursday, April 20, 2023, noon
Location: MIT CUA Room
I will describe experimental progress aimed at realizing error-corrected quantum computing systems in the motional degree of freedom of trapped-atomic ions. We have realized many rounds of quantum error correction in GKP-encoded logical qubits, extending the logical qubit lifetime by more than a factor of 3 [1,2] . Critical to these experiments was the implementation of measurement and correction suited to experimentally accessible finite-energy states. I will present theoretical and experimental progress towards implementing multi-qubit gates, as well as discussing possibilities to extend control of ions to microtrap arrays using micro-fabricated Penning traps [3], based on our recent first trapping and motional state control in such a setup.
