A Quantum Interface Between Neutral-Atoms and Trapped-Ions Quantum Registers
Ayelet Hasson, Gal Dekel, Ehud Shahar +2
Hybrid quantum systems combining neutral atoms and trapped ions offer the prospect of integrating the scalability of atom arrays with the high-fidelity control available in trapped…
Digital Predistortion of Optical Fields for Fast and High-Fidelity Entangling Gates in Trapped-Ion Qubits
Jovan Markov, Yotam Shapira, Ayelet Hasson +4
High-fidelity quantum gates require precise classical control signals, yet the analog hardware delivering these signals introduces nonlinear distortions that degrade gate performan…
Direct comparison of multi-ion optical clocks based on Ca and Sr
Yosef Sokolik, Roee Ozeri, Nitzan Akerman
We report the first direct frequency comparison between two multi-ion optical clocks based on the S to D transition in \Ca and \Sr ions. Using linear chains of up t…
Fast design and scaling of multi-qubit gates in large-scale trapped-ion quantum computers
Lee Peleg, David Schwerdt, Jonathan Nemirovsky +5
Quantum computers based on crystals of trapped ions are a prominent technology for quantum computation. A unique feature of trapped ions is their long-range Coulomb interactions, w…
Optical tweezer-controlled entanglement gates with trapped ion qubits
David Schwerdt, Lee Peleg, Gal Dekel +6
We propose an entanglement protocol where ions illuminated by optical tweezers serve as control qubits. We experimentally demonstrate this proposal with a controlled Mlmer-S$ø…
Quantum suppression of cold reactions far from the s-wave energy limit
Or Katz, Meirav Pinkas, Nitzan Akerman +2
Quantum effects in chemical reactions are most pronounced at ultracold temperatures, where only a few partial waves contribute. While interference among many partial waves is theor…
