• Abstract summary: We show that when two atomic qubits in two largely separated optical tweezers interact with a single trapped ion through Rydberg excitation of the atoms, there exists an ion-mediated atom-atom interaction. We employ this mediated interaction to demonstrate two-qubit control phase gate operation with 97% fidelity by addressing the individual atomic qubits with lasers.

• Abstract: We propose a toy model of ion-atom hybrid quantum system for quantum computing. We show that when two atomic qubits in two largely separated optical tweezers interact with a single trapped ion through Rydberg excitation of the atoms, there exists an ion-mediated atom-atom interaction which exceeds the direct interatomic interaction. We employ this mediated interaction to demonstrate two-qubit control phase gate operation with 97\% fidelity by addressing the individual atomic qubits with lasers.

• Trapped ion-mediated interactions between two distant trapped atoms [0.0]
  We show that when two largely separated atoms interact with a trapped ion via Rydberg excitation of the atoms, the ion-mediated interaction exceeds the direct atom-atom interaction by several orders of magnitude. Since the motion of the atoms is much slower than the motion of the ion, we resort to Born-Oppenheimer approximation to calculate the ion-mediated adiabatic potential.

  We investigate the possibility of creating phonon-mediated spin-spin interactions between neutral atoms trapped in optical tweezers. We show that these can be used to mediate effective spin-spin interactions or quantum logic gates between the atoms in analogy to schemes employed in trapped ions. We find arbitrarily high fidelity for the coherent time evolution of the two-atom state even at non-zero temperature.
