{"abstract":[{"lang":"eng","text":"Heavy holes confined in quantum dots are predicted to be promising candidates for the realization of spin qubits with long coherence times. Here we focus on such heavy-hole states confined in germanium hut wires. By tuning the growth density of the latter we can realize a T-like structure between two neighboring wires. Such a structure allows the realization of a charge sensor, which is electrostatically and tunnel coupled to a quantum dot, with charge-transfer signals as high as 0.3 e. By integrating the T-like structure into a radiofrequency reflectometry setup, single-shot measurements allowing the extraction of hole tunneling times are performed. The extracted tunneling times of less than 10 μs are attributed to the small effective mass of Ge heavy-hole states and pave the way toward projective spin readout measurements."}],"ddc":["539"],"year":"2017","publication_identifier":{"issn":["15306984"]},"issue":"9","publisher":"American Chemical Society","status":"public","ec_funded":1,"oa_version":"Published Version","department":[{"_id":"GeKa"}],"citation":{"apa":"Vukušić, L., Kukucka, J., Watzinger, H., &#38; Katsaros, G.
