Persistence of Entangled States and High Fidelity Quantum Gate Operations in Si/SiGe Spin Qubits at High Temperature
S. Amitonov, A. AprÃ, M. Asker +20
We characterize single- and two-qubit operations in a SiGe quantum dot array, from the perspective of its quantum information processing capabilities. The analysis includes rigorou…
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…
Tracking spin qubit frequency variations over 912 days
Kenji Capannelli, Brennan Undseth, Irene Fernández de Fuentes +9
Solid-state qubits are sensitive to their microscopic environment, causing the qubit properties to fluctuate on a wide range of timescales. The sub-Hz end of the spectrum is usuall…
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…
Running a six-qubit quantum circuit on a silicon spin qubit array
I. Fernández de Fuentes, E. Raymenants, B. Undseth +9
The simplicity of encoding a qubit in the state of a single electron spin and the potential for their integration into industry-standard microchips continue to drive the field of s…
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…
