A flying-electron quantum architecture boosted by sound – QUABS

Submission summary

The solid states systems, presently considered for quantum computation, are built from localized two-level systems. Due to the fact that they are localized, they require a fixed amount of hardware per qubit. In contrast, photon-based qubits are the only existing quantum technology that uses propagating particles. In this case, the manipulation is performed through a set of gates towards which they propagate. However, photons travel so fast that their trajectories need to be set in advance and cannot be manipulated in flight. Also, photons do not interact directly so that creating entanglement is a delicate issue. Here we propose such a quantum architecture using single flying electrons propelled be sound. We will exploit the existing Coulomb interactions between the electrons to realize electronic flying qubits and envision new quantum entanglement schemes. This will lay the foundations for a new platform of quantum processing based on single-electron transport with sound waves.
