Why Superconducting Ta Qubits Have Fewer Tunneling Two-Level Systems at the Air-Oxide Interface Than Nb Qubits
Zhe Wang, Clare C. Yu, Ruqian Wu
Superconducting qubits are a key contender for quantum computing elements, but they often face challenges like noise and decoherence from two-level systems (TLS). Tantalum (Ta) qub…
Tunable Quantum Anomalous Hall Effects in Ferromagnetic van der Waals Heterostructures
Feng Xue, Yusheng Hou, Zhe Wang +5
The quantum anomalous Hall effect (QAHE) has unique advantages in topotronic applications, but it is still challenging to realize the QAHE with tunable magnetic and topological pro…
Multifunctional Two-dimensional van der Waals Janus Magnet Cr-based Dichalcogenide Halides
Yusheng Hou, Feng Xue, Liang Qiu +2
Two-dimensional van der Waals Janus materials and their heterostructures offer fertile platforms for designing fascinating functionalities. Here, by means of systematic first-princ…
First-principles studies of spin-phonon coupling in Cr2Ge2Te6 monolayer
B. H. Zhang, Y. S. Hou, Z. Wang +1
We perform systematic first-principles calculations to investigate the spin-phonon coupling (SPC) of Cr2Ge2Te6 (CGT) monolayer (ML). It is found that the Eg phonon mode at 211.8 cm…
Two-dimensional Ferromagnetic van der Waals CrX3 (X=Cl, Br, I) Monolayers with Enhanced Anisotropy and Curie Temperature
Feng Xue, Yusheng Hou, Zhe Wang +1
Among the recently widely studied van der Waals layered magnets CrX3 (X=Cl, Br, I), CrCl3 monolayer (ML) is particularly puzzling as it is solely shown by experiments to have an in…
Hydrogen as a Source of Flux Noise in SQUIDs
Zhe Wang, Hui Wang, Clare C. Yu +1
Superconducting qubits are hampered by flux noise produced by surface spins from a variety of microscopic sources. Recent experiments indicated that hydrogen (H) atoms may be one o…
Origin and Suppression of Magnetic Flux Noise
P. Kumar, S. Sendelbach, M. A. Beck +7
Magnetic flux noise is a dominant source of dephasing and energy relaxation in superconducting qubits. The noise power spectral density varies with frequency as with $α\sim…
