Pairwise-parallel entangling gates on orthogonal modes in a trapped-ion chain
Yingyue Zhu, Alaina M. Green, Nhung H. Nguyen +3
Parallel operations are important for both near-term quantum computers and larger-scale fault-tolerant machines because they reduce execution time and qubit idling. We propose and…
Realizing two-qubit gates through mode engineering on a trapped-ion quantum computer
Ming Li, Nhung H. Nguyen, Alaina M. Green +3
Two-qubit gates are a fundamental constituent of a quantum computer and typically its most challenging operation. In a trapped-ion quantum computer, this is typically implemented w…
Experimental Measurement of Out-of-Time-Ordered Correlators at Finite Temperature
Alaina M. Green, A. Elben, C. Huerta Alderete +6
Out-of-time-ordered correlators (OTOCs) are a key observable in a wide range of interconnected fields including many-body physics, quantum information science, and quantum gravity.…
High-fidelity preparation, gates, memory and readout of a trapped-ion quantum bit
T. P. Harty, D. T. C. Allcock, C. J. Ballance +5
We implement all single-qubit operations with fidelities significantly above the minimum threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored i…
