New video “Optimizing Superconducting Thin Films for Nanowire Single Photon Detectors”

New video “Optimizing Superconducting Thin Films for Nanowire Single Photon Detectors”

Apr 29, 2020 | News Articles, Uncategorized

MIT Materials Research Laboratory 2019 Summer Scholar Leah Borgsmiller worked on niobium-aluminum thin films for superconducting nanowire single photon detectors in the QNN lab. Borgsmiller grew thin films, measured their superconducting transition temperature and...
New Publication  “Resolving photon numbers using a superconducting tapered nanowire detector”

New Publication “Resolving photon numbers using a superconducting tapered nanowire detector”

Apr 16, 2020 | News Articles

Time- and number-resolved photon detection is crucial for quantum information processing. Existing photon-number-resolving (PNR) detectors usually suffer from limited timing and dark-count performance or require complex fabrication and operation. Here, we demonstrate...
New Publication “Demonstration of sub-3 ps temporal resolution with a superconducting nanowire single-photon detector”

New Publication “Demonstration of sub-3 ps temporal resolution with a superconducting nanowire single-photon detector”

Mar 3, 2020 | News Articles

Improvements in temporal resolution of single-photon detectors enable increased data rates and transmission distances for both classical and quantum optical communication systems, higher spatial resolution in laser ranging, and observation of shorter-lived...
New Grant “Nanostructured optical-field samplers for visible to near-infrared time-domain spectroscopy”

New Grant “Nanostructured optical-field samplers for visible to near-infrared time-domain spectroscopy”

Feb 16, 2020 | News Articles

QNN awarded new SENSE.nano seed grant for the development of nanostructured optical-field samplers for visible to near-infrared time-domain spectroscopy. More information on this project and the other SENSE.nano awards may be found here.
New Publication “Single-Photon Single-Flux Coupled Detectors”

New Publication “Single-Photon Single-Flux Coupled Detectors”

Jan 7, 2020 | News Articles

In this work, we present a novel device that is a combination of a superconducting nanowire single-photon detector and a superconducting multilevel memory. We show that these devices can be used to count the number of detections through single-photon to single-flux...
New Publication “A general theoretical and experimental framework for nanoscale electromagnetism”

New Publication “A general theoretical and experimental framework for nanoscale electromagnetism”

Dec 12, 2019 | News Articles

The macroscopic electromagnetic boundary conditions, which have been established for over a century, are essential for the understanding of photonics at macroscopic length scales. Even state-of-the-art nanoplasmonic studies, exemplars of extremely interface-localized...
