Coherence Protection for Mobile Spin Qubits in Silicon
Jan A. Krzywda, Yuta Matsumoto, Maxim De Smet +6
Mobile spin qubit architectures promise flexible connectivity for efficient quantum error correction and relaxed device layout constraints, but their viability rests on preserving…
Distributing entanglement between distant semiconductor qubit registers using a shared-control shuttling link
Zarije Ademi, Marion Bassi, Cécile X. Yu +8
Semiconductor quantum processors have potential to scale to modular quantum computers, in which qubit registers are coupled by quantum links, enabling high connectivity and space f…
Spin-orbit-enabled realization of arbitrary two-qubit gates on moving spins
D. Fernández-Fernández, Y. Matsumoto, L. M. K. Vandersypen +2
Shuttling spin qubits in systems with large spin-orbit interaction (SOI) can cause errors during motion. However, in this work, we demonstrate that SOI can be harnessed to implemen…
Operating semiconductor qubits without individual barrier gates
A. S. Ivlev, D. R. Crielaard, M. Meyer +8
Semiconductor spin qubits have emerged as a promising platform for quantum computing, following a significant improvement in their control fidelities over recent years. Increasing…
High-fidelity single-spin shuttling in silicon
Maxim De Smet, Yuta Matsumoto, Anne-Marije J. Zwerver +12
The computational power and fault-tolerance of future large-scale quantum processors derive in large part from the connectivity between the qubits. One approach to increase connect…
Accurate, transferable, and verifiable machine-learned interatomic potentials for layered materials
Johnathan D. Georgaras, Akash Ramdas, Chung Hsuan Shan +4
Twisted layered van-der-Waals materials often exhibit unique electronic and optical properties absent in their non-twisted counterparts. Unfortunately, predicting such properties i…
