Protected Hybrid Superconducting Qubit in an Array of Gate-Tunable Josephson Interferometers
PRX Quantum, 2022 We propose a protected qubit based on a modular array of superconducting islands connected by semiconductor Josephson interferometers. The individual interferometers realize effective cos2ϕ elements that exchange “pairs of Cooper pairs” between the ...

Advanced Materials, EarlyView.Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Quantum SU(1,1) interferometers: Basic principles and applications
APL Photonics, 2020 A new type of quantum interferometer was recently realized that employs parametric amplifiers (PAs) as the wave splitting and mixing elements. The quantum behavior stems from the PAs, which produce quantum entangled fields for probing the phase change ...

Advanced Materials, EarlyView.We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

Optimal squeezing for high-precision atom interferometers [PDF]
, 2023 We show that squeezing is a crucial resource for interferometers based on the spatial separation of ultra-cold interacting matter. Atomic interactions lead to a general limitation for the precision of these atom interferometers, which can neither be ...

Gate‐Induced Critical Current Modulation in W–C Nanowires: The Role of Fabrication
Advanced Materials Technologies, EarlyView.Focused ion beam induced deposition (FIBID) enables precise control of superconducting W–C nanowire devices. Introducing a Ga+ focused ion beam (FIB) cleaning step reduces substrate damage and suppresses leakage currents, shifting gating thresholds to higher voltages.
