Quantum logic for state preparation, readout, and leakage detection with binary subspace measurements
R. Tyler Sutherland
We discuss a general technique for using quantum logic spectroscopy to perform quantum non-demolition (QND) measurements that determine which of two subspaces a logic ion is in. We…
Dressing trapped ions with integrated wires
R. Tyler Sutherland
We discuss dressing trapped ions with the near field of a trap integrated wire. Ramping a dressing field on/off adiabatically before/after an operation changes its effective Hamilt…
Cooling trapped ions with phonon rapid adiabatic passage
M. I. Fabrikant, P. Lauria, I. S. Madjarov +2
In recent demonstrations of the quantum charge-coupled device (QCCD) computer architecture, circuit times are dominated by cooling. Some motional modes of multi-ion crystals take o…
Passive dynamical decoupling of trapped ion qubits and qudits
R. Tyler Sutherland, Stephen D. Erickson
We propose a method to dynamically decouple every magnetically sensitive hyperfine sublevel of a trapped ion from magnetic field noise, simultaneously, using integrated circuits to…
Laser-free trapped ion entangling gates with AESE: Adiabatic Elimination of Spin-motion Entanglement
R. Tyler Sutherland, M. Foss-Feig
We discuss a laser-free, two-qubit geometric phase gate technique for generating high-fidelity entanglement between two trapped ions. The scheme works by ramping the spin-dependent…
