We demonstrate the use of an optical frequency comb to coherently control and entangle atomic qubits. A train of off-resonant ultrafast laser pulses is used to efficiently and coherently transfer population between electronic and vibrational states of trapped atomic ions and implement an entangling quantum logic gate with high fidelity. This technique can be extended to the high field regime where operations can be performed faster than the trap frequency. This general approach can be applied… Expand
Quantum control of qubits and atomic motion using ultrafast laser pulses
Pulsed lasers offer significant advantages over continuous wave (CW) lasers in the coherent control of qubits. Here we review the theoretical and experimental aspects of controlling the internal andExpand
Robust quantum gates between trapped ions using shaped pulses
Abstract We improve two existing entangling gate schemes between trapped ion qubits immersed in a large linear crystal. Based on the existing two-qubit gate schemes by applying segmented forces onExpand
Quantum Networks with Atoms and Photons
Trapped atomic ions are standards for quantum information processing, as all of the fundamental quantum operations have been demonstrated in small collections of atoms. Current work is concentratedExpand
Quantum Parametric Oscillator with Trapped Ions.
TLDR
The Coulomb interaction between two trapped ions is exploited to achieve strong nonlinear coupling between normal modes of motion at the single-phonon level and this coupling is applied to directly measure the parity and Wigner functions of the ions' motional states. Expand
Quantum logic for the control and manipulation of molecular ions using a frequency comb
We propose a scheme for the preparation, manipulation and detection of quantum states of single molecular ions. In this scheme, molecular and atomic ions are confined in radio-frequency Paul trap andExpand
Individual addressing of trapped 171Yb+ ion qubits using a microelectromechanical systems-based beam steering system
The ability to individually manipulate the increasing number of qubits is one of the many challenges towards scalable quantum information processing with trapped ions. Using micro-mirrors fabricatedExpand

TLDR
This work describes scalable solutions to the challenges of scaling quantum computer hardware at the interface between the qubits and the classical control signals used to manipulate them. Expand
Error compensation of single-qubit gates in a surface-electrode ion trap using composite pulses
The fidelity of laser-driven quantum logic operations on trapped ion qubits tend to be lower than microwave-driven logic operations due to the difficulty of stabilizing the driving fields at the ionExpand
Beat note stabilization of mode-locked lasers for quantum information processing.
We stabilize a chosen radio frequency beat note between two optical fields derived from the same mode-locked laser pulse train in order to coherently manipulate quantum information. This scheme doesExpand

TLDR
I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
