We show that SNSPDs can also be used to study continuous variables of optical quantum states by performing homodyne detection at a bandwidth of 400 kHz. By measuring the interference of a continuous-wave field of a local oscillator with the field of the vacuum state using two SNSPDs, we show that the variance of the difference in count rates is linearly proportional to the photon flux of the local oscillator over almost five orders of magnitude. The resulting shot-noise clearance of (46.0 ± 1.1) dB is the highest reported clearance for a balanced optical homodyne detector, demonstrating their potential for measuring highly squeezed states in the continuous-wave regime. In addition, we measured a CMRR = 22.4 dB. From the joint click counting statistics, we also measure the phase-dependent quadrature of a weak coherent state to demonstrate our device’s functionality as a homodyne detector.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Optica Quantum","article_number":"1","language":[{"iso":"eng"}],"project":[{"_id":"191","name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform"},{"name":"ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications","_id":"239"},{"_id":"209","name":"ISOQC: Quantenkommunikation mit integrierter Optik im Zusammenhang mit supraleitender Elektronik"}],"_id":"50840","user_id":"55629","department":[{"_id":"15"},{"_id":"623"}]},{"date_created":"2023-10-24T06:43:16Z","author":[{"orcid":"0000-0003-0663-5587","last_name":"Thiele","full_name":"Thiele, Frederik","id":"50819","first_name":"Frederik"},{"first_name":"Thomas","last_name":"Hummel","id":"83846","full_name":"Hummel, Thomas"},{"full_name":"McCaughan, Adam N.","last_name":"McCaughan","first_name":"Adam N."},{"first_name":"Julian","last_name":"Brockmeier","full_name":"Brockmeier, Julian","id":"44807"},{"first_name":"Maximilian","last_name":"Protte","id":"46170","full_name":"Protte, Maximilian"},{"first_name":"Victor","full_name":"Quiring, Victor","last_name":"Quiring"},{"first_name":"Sebastian","last_name":"Lengeling","full_name":"Lengeling, Sebastian","id":"44373"},{"first_name":"Christof","full_name":"Eigner, Christof","id":"13244","orcid":"https://orcid.org/0000-0002-5693-3083","last_name":"Eigner"},{"last_name":"Silberhorn","id":"26263","full_name":"Silberhorn, Christine","first_name":"Christine"},{"first_name":"Tim","last_name":"Bartley","id":"49683","full_name":"Bartley, Tim"}],"volume":31,"publisher":"Optica Publishing Group","date_updated":"2023-11-27T08:43:33Z","doi":"10.1364/oe.492035","title":"All optical operation of a superconducting photonic interface","issue":"20","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"citation":{"apa":"Thiele, F., Hummel, T., McCaughan, A.

Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse.

We present a method to replace the electrical input by supplying the required bias current via the photocurrent of a photodiode situated on the cold stage of the cryostat. Light is guided to the bias photodiode through an optical fiber, which enables a lower thermal conduction and galvanic isolation between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device to bias an SNSPD, we characterize the count rate dependent on the optical power incident on the photodiode. This configuration of the SNSPD and photodiode shows an expected plateau in the single photon count rate with an optical bias power on the photodiode above 6.8 µW. Furthermore, we compare the same detector under both optical and electrical bias, and show there is no significant changes in performance. This has the advantage of avoiding an electrical input cable, which reduces the latent heat load by a factor of 100 and, in principle, allows for low loss RF current supply at the cold stage. </jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"APL Photonics","article_number":"081303","keyword":["Computer Networks and Communications","Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}],"_id":"33673","user_id":"83846","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"}],"year":"2022","citation":{"short":"F.
