Motional squeezing for trapped ion transport and separation
R. T. Sutherland, S. C. Burd, D. H. Slichter +2
Transport, separation, and merging of trapped ion crystals are essential operations for most large-scale quantum computing architectures. In this work, we develop a theoretical fra…
High-fidelity laser-free universal control of two trapped ion qubits
R. Srinivas, S. C. Burd, H. M. Knaack +9
Universal control of multiple qubits -- the ability to entangle qubits and to perform arbitrary individual qubit operations -- is a fundamental resource for quantum computation, si…
Laser-free trapped-ion entangling gates with simultaneous insensitivity to qubit and motional decoherence
R. T. Sutherland, R. Srinivas, S. C. Burd +7
The dominant error sources for state-of-the-art laser-free trapped-ion entangling gates are decoherence of the qubit state and the ion motion. The effect of these decoherence mecha…
Trapped-ion spin-motion coupling with microwaves and a near-motional oscillating magnetic field gradient
R. Srinivas, S. C. Burd, R. T. Sutherland +5
We present a new method of spin-motion coupling for trapped ions using microwaves and a magnetic field gradient oscillating close to the ions' motional frequency. We demonstrate an…
Versatile laser-free trapped-ion entangling gates
R. T. Sutherland, R. Srinivas, S. C. Burd +6
We present a general theory for laser-free entangling gates with trapped-ion hyperfine qubits, using either static or oscillating magnetic-field gradients combined with a pair of u…
