Developing and characterizing free space and integrated SNSPD’s

They can be harnessed in photonic quantum schemes, e.g. for quantum communication or computation protocols, which require highly efficient, fast, and reliable detectors. Superconducting nanowire single photon detectors (SNSPD’s) are promising detectors which already outperform conventional single photon detectors.

I will develop, characterize, and optimize SNSPD’s for photonic quantum technologies. My focus will be on optimizing key parameters such as

• the detection efficiency which is necessary to make quantum protocols feasible and secure,
• the timing-jitter allowing precise measurements further enhancing e.g. the security of protocols,
• low dark counts which are crucial for a good signal-to-noise ratio,
• detection rates to decrease the necessary time for protocols.
  I will further explore novel sensing schemes which make use of the superior capabilities of these detectors.
