Opportunities for quantum processing and error correction with trapped molecules

Abstract

Standard implementations of quantum error correction in atomic processors devote multiple atoms and many inter-atom gates to each robust qubit.  A co-design strategy to streamline this approach should focus on both tailoring the code to the native hardware errors and reducing the resource cost of the QEC cycle.  Absorption-emission (Æ) codes are designed to do both, using a manifold of high total angular momentum (J) for the encoding.  While appropriate states for this can be identified in a couple of heroic atoms, long-lived manifolds with high J are trivially available in even the simplest of molecules.  I will discuss progress in developing molecular species and primitives for processing and readout that are applicable to quantum computing, precision measurement and ultracold chemistry.
