Pulsed force sequences for fast phase-insensitive quantum gates in trapped ions

A M Steane, G Imreh, J P Home +1

We show how to create quantum gates of arbitrary speed between trapped ions, using a laser walking wave, with complete insensitivity to drift of the optical phase, and requiring co…

Experimental recovery of a qubit from partial collapse

J. A. Sherman, M. J. Curtis, D. J. Szwer +4

We describe and implement a method to restore the state of a single qubit, in principle perfectly, after it has partially collapsed. The method resembles the classical Hahn spin-ec…

Implementation of a symmetric surface electrode ion trap with field compensation using a modulated Raman effect

D. T. C. Allcock, J. A. Sherman, D. N. Stacey +8

We describe the fabrication and characterization of a new surface-electrode Paul ion trap designed for experiments in scalable quantum information processing with Ca+. A notable fe…

High-fidelity readout of trapped-ion qubits

A. Myerson, D. Szwer, S. Webster +7

We demonstrate single-shot qubit readout with fidelity sufficient for fault-tolerant quantum computation, for two types of qubit stored in single trapped calcium ions. For an optic…

A long-lived memory qubit on a low-decoherence quantum bus

D. M. Lucas, B. C. Keitch, J. P. Home +5

We demonstrate long-lived coherence in internal hyperfine states of a single \Ca{43} trapped-ion qubit $[T_2=1.2(2)\s]$, and in external motional states of a single \Ca{40} trapped…

Long-lived mesoscopic entanglement outside the Lamb-Dicke regime

M. J. McDonnell, J. P. Home, D. M. Lucas +7

We create entangled states of the spin and motion of a single Ca ion in a linear ion trap. The motional part consists of coherent states of large separation and long coh…
