Understanding multiscale disorder in superconducting nanowire single photon detectors
Nirjhar Sarkar, Ronan Gourgues, Yueh-Chun Wu +7
Superconducting nanowire single-photon detectors are central to applications across quantum information science. Yet, their performance is limited by the effects of disorder and el…
Nanosculpting lateral weak link junctions in superconducting Fe(Te,Se)/Bi2Te3 with focused Si++ ions and implications on vortex pinning
Debarghya Mallick, Sujoy Ghosh, An Hsi Chen +10
Superconductor-normal-superconductor (SC-N-SC) weak links enable Cooper-pair tunneling and serve as Josephson junctions (JJs) used in modern superconducting qubits. Conventional JJ…
Probing Boron Vacancy Defects in hBN via Single Spin Relaxometry
Alex L. Melendez, Ruotian Gong, Guanghui He +14
Spin defects in solids offer promising platforms for quantum sensing and memory due to their long coherence times and optical addressability. Here, we integrate a single nitrogen-v…
Defect Engineering in Large-Scale CVD-Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics
Ivan V. Vlassiouk, Yueh-Chun Wu, Alexander Puretzky +19
Recently, numerous techniques have been reported for generating optically active defects in exfoliated hexagonal boron nitride (hBN), which hold transformative potential for quantu…
