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…
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…
Optimization and implementation of a surface-electrode ion trap junction
Chi Zhang, Karan K Mehta, Jonathan P Home
We describe the design of a surface-electrode ion trap junction, which is a key element for large-scale ion trap arrays. A bi-objective optimization method is used for designing th…
Generation of a maximally entangled state using collective optical pumping
M. Malinowski, C. Zhang, V. Negnevitsky +7
We propose and implement a novel scheme for dissipatively pumping two qubits into a singlet Bell state. The method relies on a process of collective optical pumping to an excited l…
Design, fabrication and characterisation of a micro-fabricated double-junction segmented ion trap
Chiara Decaroli, Roland Matt, Robin Oswald +4
We describe the implementation of a three-dimensional Paul ion trap fabricated from a stack of precision-machined silica glass wafers, which incorporates a pair of junctions for 2-…
Bias in error-corrected quantum sensing
Ivan Rojkov, David Layden, Paola Cappellaro +2
The sensitivity afforded by quantum sensors is limited by decoherence. Quantum error correction (QEC) can enhance sensitivity by suppressing decoherence, but it has a side-effect:…
