High-Q superconducting microwave resonators using MBE titanium nitride
Anand Ithepalli, Haoran Lu, Eegene Clara Chung +9
The authors use molecular beam epitaxy to grow high-quality TiN thin films on sapphire, achieving very low X‑ray rocking curve widths and superconducting coplanar waveguide resonat…
Low-loss Nb on Si superconducting resonators from a dual-use spintronics deposition chamber and with acid-free post-processing
Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee +13
Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally…
Kramers-protected hardware-efficient error correction with Andreev spin qubits
Haoran Lu, Isidora Araya Day, Anton R. Akhmerov +2
We propose an architecture for bit-flip error correction of Andreev spins that is protected by Kramers' degeneracy. Specifically, we show that a coupling network of linear inductor…
Andreev spin relaxation time in a shadow-evaporated InAs weak link
Haoran Lu, David F. Bofill, Zhenhai Sun +4
Andreev spin qubits are a new qubit platform that merges superconductivity with semiconductor physics. The mechanisms dominating observed energy relaxation remain unidentified. We…
