Combining two separate degrees of freedom into a single quantum system in order to accommodate long memory time and fast processing speed in a single platform.

Previous results: Feasibility study of combining superconducting elements with trapped ions (Kotler et.al. “Hybrid quantum systems with trapped charged particles”, PRA 95, 022327 (2017)). We were able to rule out many architectures that were discussed in the community. On the converse, we showed that using electrons to carry the quantum information would enable processing speeds that are as fast as superconducting qubits (10s of nanoseconds) while retaining information as long as atomic systems (seconds).
