John J. Bollinger (Fed)


John Bollinger is a staff scientist and current group leader of the NIST Ion Storage Group in the Time and Frequency Div. of the National Institute of Standards and Technology (NIST). He was a principal on early NIST studies employing laser-cooled ions for microwave frequency standards and then carried out studies on the collective and cold plasma behavior of laser-cooled ion crystals in Penning traps, including precise characterization of the plasma modes, crystal equilibria, and structural phase transitions. His recent work has focused on the use of trapped ion crystals of several hundred ions confined in Penning ion traps for quantum information studies, including quantum simulation and quantum metrology. John received undergraduate degrees in physics and mathematics from Cornell University in 1974, and a Ph.D. in physics from Harvard University in 1981. John is a Fellow of the American Physical Society (APS). Recent service includes serving on the chair line (2017-2021) of the Div. of Atomic, Molecular, and Optical Physics (DAMOP) of APS.

Robustness of the projected squeezed state protocol

Byron Alexander, John J. Bollinger, Mark Tame
Projected squeezed (PS) states are multipartite entangled states generated by unitary spin squeezing, followed by a quantum measurement and post-selection. They

Experimental speedup of quantum dynamics through squeezing

Shaun Burd, Hannah Knaack, Raghavendra Srinivas, Christian Arenz, Alejandra Collopy, Laurent Stephenson, Andrew C. Wilson, David Wineland, Dietrich Leibfried, John J. Bollinger, David Allcock, Daniel Slichter
We show experimentally that a broad class of interactions involving quantum harmonic oscillators can be made stronger (amplified) using a unitary squeezing

Bilayer crystals of trapped ions for quantum information processing

Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Maria Rey, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on
