Progress towards remote entanglement between a trapped ion and a solid state qubit

ORAL

Abstract

Trapped ytterbium ions have the longest memories (coherence times) of any qubit, yet gate speeds are slow relative to solid state qubit systems. A hybrid quantum system has the potential to take advantage of both of these properties. Donor qubits in zinc oxide have an optical transition near the cooling transition for ytterbium ions, making these two species interesting candidates for a remote entanglement experiment. However, the mismatch in temporal profile between photons emitted from disparate qubits remains an outstanding challange. We present a scheme for overcoming this temporal mismatch using established pulse-shaping techniques, and progress towards building a system for performing the experiment.
