Design and characterization of a cryogenic vacuum chamber for ion trapping experiments
D. M. Hartsell, J. M. Gray, C. M. Shappert +5
We present the design and characterization of a cryogenic vacuum chamber incorporating mechanical isolation from vibrations, a high numerical-aperture in-vacuum imaging objective,…
Rapid Exchange Cooling with Trapped Ions
Spencer D. Fallek, Vikram S. Sandhu, Ryan A. McGill +4
The trapped-ion quantum charge-coupled device (QCCD) architecture is a leading candidate for advanced quantum information processing. In current QCCD implementations, imperfect ion…
Characterization of Fast Ion Transport via Position-Dependent Optical Deshelving
Craig R. Clark, Creston D. Herold, J. True Merrill +11
Ion transport is an essential operation in some models of quantum information processing, where fast ion shuttling with minimal motional excitation is necessary for efficient, high…
Transport-enabled entangling gate for trapped ions
Holly N. Tinkey, Craig R. Clark, Brian C. Sawyer +1
We implement a two-qubit entangling Mølmer-Sørensen interaction by transporting two co-trapped ions through a stationary, bichromatic optical beam within a s…
High-Fidelity Bell-State Preparation with Ca Optical Qubits
Craig R. Clark, Holly N. Tinkey, Brian C. Sawyer +10
Entanglement generation in trapped-ion systems has relied thus far on two distinct but related geometric phase gate techniques: Molmer-Sorensen and light-shift gates. We recently p…
Quantum process tomography of a Mølmer-Sørensen gate via a global beam
Holly N Tinkey, Adam M Meier, Craig R Clark +2
We present a framework for quantum process tomography of two-ion interactions that leverages modulations of the trapping potential and composite pulses from a global laser beam to…
