Penning micro-trap for quantum computing
Shreyans Jain, Tobias Sägesser, Pavel Hrmo +8
Trapped ions in radio-frequency traps are among the leading approaches for realizing quantum computers, due to high-fidelity quantum gates and long coherence times. However, the us…
Grating design methodology for tailored free-space beam-forming
Gillenhaal J. Beck, Jonathan P. Home, Karan K. Mehta
We present a design methodology for free-space beam-forming with general profiles from grating couplers which avoids the need for numerical optimization, motivated by applications…
Two-qubit operations for finite-energy Gottesman-Kitaev-Preskill encodings
Ivan Rojkov, Paul Moser Röggla, Martin Wagener +4
We present techniques for performing two-qubit gates on Gottesman-Kitaev-Preskill (GKP) codes with finite energy, and find that operations designed for ideal infinite-energy codes…
Integration of a high finesse cryogenic build-up cavity with an ion trap
Oliver Wipfli, Henry Fernandes Passagem, Christoph Fischer +2
We report on the realization of a hemispherical optical cavity with a finesse of F = 13000 sustaining inter-cavity powers of 10 kW, which we operate in a closed-cycle cryostat vacu…
