Sound and Efficient Certification of High-Quality Qubit Operations: Theory and Experiment
Nikolai Miklin, Jan Nöller, José Martínez +4
Can a high-quality quantum gate be certified when uncharacterized state-preparation and measurement errors are dominant? Can this be achieved with low experimental overhead? Here,…
A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…
Efficient LLM-Generated Shuttling Compilers for Complex Trapped-Ion Architectures
Fabian Kreppel, Reza Salkhordeh, Ferdinand Schmidt-Kaler +1
Trapped-ion quantum computers rely on shuttling compilers, which cast an input algorithm into a sequence of ion-qubit movements within a given architecture. We present the first st…
Generation of continuous-wave laser light at 148.4 nm using cavity-enhanced second harmonic generation in
Keerthan Subramanian, Hiroki Tanaka, Simon J. Herr +22
We experimentally investigate the potential of crystals to create a continuous-wave (CW) solid state laser at the vacuum ultraviolet (VUV) wavelength of 148.4 nm via cavi…
Shuttling in Bidimensional Segmented Ion-Trap Quantum Processors with T-Junctions
J. Durandau, C. A. Brunet, F. Schmidt-Kaler +3
Shuttle-based trapped ion quantum processors typically employ a one-dimensional (1D) linear architecture to transport ion-qubits between one ore more laser interaction zones where…
Shuttling Compiler for Trapped-Ion Quantum Computers Based on Large Language Models
Fabian Kreppel, Reza Salkhordeh, Ferdinand Schmidt-Kaler +1
We present the first shuttling compiler based on large language models (LLMs) for trapped-ion quantum computers, where qubits are shuttled between segments for gate execution and q…
