VECSEL systems for quantum information processing with trapped beryllium ions

March 10, 2023
Author(s)
Shaun C. Burd, Jussi-Pekka Penttinen, Panyu Hou, Hannah Knaack, Sanna Ranta, Mika Maki, Emmi Kantola, Mircea Guina, Daniel Slichter, Dietrich Leibfried, Andrew C. Wilson
We demonstrate two systems based on vertical-external-cavity surface-emitting lasers (VECSELs) for producing ultraviolet laser light at wavelengths of 235 and 313 nm. The systems are suitable for quantum information processing with trapped beryllium ions

High-fidelity laser-free universal control of trapped ion qubits

September 8, 2021
Author(s)
Raghavendra Srinivas, Emanuel Knill, Robert Sutherland, Alexander T. Kwiatkowski, Hannah M. Knaack, Scott Glancy, David J. Wineland, Shaun C. Burd, Dietrich Leibfried, Andrew C. Wilson, David T. Allcock, Daniel Slichter
Universal control of multiple qubits—the ability to entangle qubits and to perform arbitrary individual qubit operations—is a fundamental resource for quantum computing, simulation and networking. Qubits realized in trapped atomic ions have shown the

Quantum amplification of boson-mediated interactions

Shaun C. Burd, Raghavendra Srinivas, Hannah M. Knaack, Wenchao Ge, Andrew C. Wilson, David J. Wineland, Dietrich Leibfried, John J. Bollinger, David T. Allcock, Daniel Slichter
Strong and precisely controlled interactions between quantum objects are essential for quantum information processing\citeSackett2000,Majer2007}, simulation\citeBritton2012}, and sensing\citeHosten2016a,Cox2016}, and for the formation of exotic quantum

Laser-free trapped-ion entangling gates with simultaneous insensitivity to qubit and motional decoherence

April 29, 2020
Author(s)
R. T. Sutherland, Raghavendra Srinivas, Shaun C. Burd, Hannah M. Knaack, Andrew C. Wilson, David J. Wineland, Dietrich Leibfried, David T. Allcock, Daniel Slichter, S. B. Libby
The dominant error sources for state-of-the-art implementations of laser-free trapped-ion entangling gates are decoherence of the qubit state and motion. The gate error from these decoherence mechanisms can be suppressed with additional control fields, or
