Quantum amplification of mechanical oscillator motion
S. C. Burd, R. Srinivas, J. J. Bollinger +5
Detection of the weakest forces in nature and the search for new physics are aided by increasingly sensitive measurements of the motion of mechanical oscillators. However, the atta…
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…
Coherently displaced oscillator quantum states of a single trapped atom
Katherine C. McCormick, Jonas Keller, David J. Wineland +2
Coherently displaced harmonic oscillator number states of a harmonically bound ion can be coupled to two internal states of the ion by a laser-induced motional sideband interaction…
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…
Can a periodically driven particle resist laser cooling and noise?
A. Maitra, D. Leibfried, D. Ullmo +1
Studying a single atomic ion confined in a time-dependent periodic anharmonic potential, we find large amplitude trajectories stable for millions of oscillation periods in the pres…
Improving Super-Resolution Methods via Incremental Residual Learning
Muneeb Aadil, Rafia Rahim, Sibt ul Hussain
Recently, Convolutional Neural Networks (CNNs) have shown promising performance in super-resolution (SR). However, these methods operate primarily on Low Resolution (LR) inputs for…
