Query: Pulsed force sequences for fast phase-insensitive quantum gates in
  trapped ions   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 cooling only to the Lamb-Dicke regime. We present pulse
sequences that satisfy the requirements and are easy to produce in the
laboratory.
