Ever since its introduction in 1834 by William Fox Talbot, (1−3) polarimetry has been one of the main techniques for investigating the world around us.

2.3. Sample Preparation and ISF Collection To evaluate the pH sensitivity of the silicon nanowire sensors, we prepared five solutions with pH values of 6.58, 6.85, 7.08, 7.47, and 7.88 in HEPES and MES buffers. These solutions are referred to as the “buffer” set. Additionally, we prepared five solutions with pH values of 6.52, 6.87, 7.16, 7.52, and 7.96 in diluted human sera, which are referred to as the “ISF-like” set.

INTRODUCTION Spins in silicon are promising qubits for future quantum information technologies with long spin coherence times in 28Si and the technological benefit of industry-compatible silicon fabrication processes. Great progress has been made on individual Si:P donor spin qubits including high-fidelity single-qubit logic gates and single-spin measurement (1, 2).
