On-chip cavity quantum phonodynamics and acceptor qubits in silicon

On-chip cavity quantum phonodynamics and acceptor qubits in silicon

We show how long-lived and tunable acceptor impurity states in silicon nanomechanical cavities can play the role of a matter non-linearity for coherent phonons just as, e.g., the J...

Introducing the phoniton: A sound-based analogue of cavity-QED, a tool for controlling sound at the quantum level

Introducing the phoniton: A sound-based analogue of cavity-QED, a tool for controlling sound at the quantum level

This work explores the possibility of a new, man-made quantum object: a hybridization of a localized, long-lived phonon (a quantum of sound) and a matter excitation. That this is p...
