文章介绍了作者用介观输运器件[如量子点接触(QPC)或单电子晶体管(SET)]测量固态量子比特的原理和特性,特别着重地介绍了作者最近在处理被测量子比特和介观测量仪器之间的关联方面的新进展。
This paper gives a brief introduction to the measurement of a solid state charge qubit by a mesoscopic detector such as quantum point contact (QPC) or single electron transistor (SET), and particular atten tion will be paid on the new underslanding of the qubit-detector correlation.
