Improving coherence is a fundamental challenge in quantum simulation and sensing experiments with trapped ions. Here we discuss, experimentally demonstrate, estimate the potential impacts of two different protocols that enhance, through motional parametric excitation, coherent spin-motion coupling ions obtained spin-dependent force.

Previous work has shown that the one-dimensional (1D) inviscid compressible flow (Euler) equations admit a wide variety of scale-invariant solutions (including famous Noh, Sedov, and Guderley shock solutions) when included equation state (EOS) closure model assumes certain form. However, this EOS class does not include even simple models used for compression crystalline solids, including many broadly applicable representations Mie-Gr\"uneisen EOS. Intuitively, incompatibility naturally...
Penning traps have been used for performing quantum simulations and sensing with hundreds of ions provide a promising route toward scaling up trapped ion platforms because the ability to trap control or thousands in two- three-dimensional crystals. In both more common radiofrequency Paul traps, lasers are often drive multiqubit entangling operations. A leading source decoherence these operations is off-resonant spontaneous emission. While many computers simulators utilize clock qubits, other...
Single trapped ion qubit is an excellent candidate for quantum computation and information, with additional ability to coherently couple single photons. Efficient fluorescence collection the most challenging part in remote entangled state generation. To address this issue, we developed trap combining a reflective parabolic surface electrodes. This design covers solid angle of 2pi steradians, allows precise placement at focal point parabola. We measured approximately 39% from mirror, analyzed...
This work is concerned with the use of Guderley's converging shock wave solution inviscid compressible flow equations as a verification test problem for simulation software. In practice, this effort complicated by both semi-analytical nature and infinite spatial/temporal extent solution. Methods can be devised intention ameliorating inconsistency finite computational simulation; exact strategy will depend on code archetypes under investigation. For example, scale-invariant propagation...
We propose an optical scheme to generate entangled state between a trapped ion and solid donor qubit through which-path erasure of identical photons emitted from the two systems. The proposed leverages similar transition frequencies In bound excitons in ZnO P21/2 S21/2 Yb+. lifetime relevant ionic is longer than that system by factor 6, leading mismatch temporal profiles photons. A detuned cavity-assisted Raman weakly excites with shaped laser pulse 0.99 overlap Yb+ emission partially shift...
