Population-Based Discrimination of Classical and Few-Photon Microwave Fields with a Flux-Tunable Transmon Qudit

Interactions between few-photon microwave fields and superconducting artificial atoms provide a method to study photon statistics and manipulate quantum states for photonic quantum information processing. Superconducting transmons couple to microwave fields through an anharmonic...

Single‐Photon Emitters Based on Ge‐V Centers in Nanoparticles Obtained From CVD‐Grown Nanocrystalline Diamond Films

A method for obtaining luminescent diamond nanoparticles doped with germanium from nanocrystalline diamond (NCD) films grown by microwave plasma‐assisted chemical vapor deposition (MPCVD) is presented. Thermal etching in the presence of an alkali metal nitrate enables the selecti...

Individual Patterns of Heart Rate Variability During Prolonged Cognitive Load with Mental Fatigue Induction

We investigated individual dynamics of cognitive performance and heart rate variability (HRV) measures during prolonged mental load. The aim of this study was to identify characteristic phases of cognitive performance and individual patterns of physiological responses induced by...
