Joint Spectral Measurements at the Hong-Ou-Mandel Interference Dip

Thomas Gerrits, Francesco F. Marsili, Varun B. Verma, Adriana E. Lita, Antia A. Lamas-Linares, Jeffrey A. Stern, Matthew Shaw, William Farr, Richard P. Mirin, Sae Woo Nam
We employed a 2 channel single-photon detection system with high detection efficiency and low jitter to characterize the joint spectral distribution (JSD) of the correlated photons emerging from a Hong-Ou-Mandel interference arrangement. We show the JSDs

Extending single-photon optimized superconducting transition edge sensors beyond the single-photon counting regime

Photon number resolving transition-edge sensors (TES) are the cutting-edge enabling technology for high quantum efficiency photon counting when the number of photons of an input state needs to be determined. The TES developed at NIST reliably show system

Typically, transition edge sensors resolve photon number of up to 10 or 20 photons, depending on the wavelength and TES design. We extend that dynamic range up to 1000 photons, while maintaining sub- shot noise detection process uncertainty of the number

Thomas Gerrits, Nick Thomas-Peter, James Gates, Adriana E. Lita, Benjamin Metcalf, Brice R. Calkins, Nathan A. Tomlin, Anna E. Fox, Antia A. Lamas-Linares, Justin Spring, Nathan Langford, Richard P. Mirin, Peter Smith, Ian Walmsley, Sae Woo Nam
We demonstrate the operation of an integrated photon number resolving transition edge sensor (TES), operating in the telecom band at 1550 nm, employing an evanescently coupled design that allows the detector to be placed at arbitrary locations within a

Transition edge sensors with low jitter and fast recovery times

Antia A. Lamas-Linares, Nathan A. Tomlin, Brice R. Calkins, Adriana E. Lita, Thomas Gerrits, Joern Beyer, Richard P. Mirin, Sae Woo Nam
Superconducting transition edge sensors (TES) for single photon detection have been shown to have almost perfect quantum efficiency (98%) at a wide range of wavelengths. Their high quantum efficiency combined with their ability to intrisically measure the

An algorithm for finding clusters with a known distribution and its application to photon-number resolution using a superconducting transition-edge sensor

Improving photon-number resolution of single-photon sensitive detectors is important for many applications, as is extending the range of such detectors. Here we seek improved resolution for a particular Superconducting Transition-Edge Sensor (TES) through

We illuminate a photon-number-resolving transition edge sensor with strong pulses of light containing up to 6.7 million photons (0.85 pJ per pulse). These bright pulses heat the sensor far beyond its transition edge into the normal resistance regime. We

We demonstrate an integrated photon-number resolving detector, operating in the telecom band at 1550 nm, employing an evanescently coupled design that allows the detector to be placed at arbitrary locations within a planar optical circuit. Up to 5 photons

Conclusive quantum steering with superconducting transition-edge sensors

Devin H. Smith, Marcelo de Almeida, Gillett Geoff, Branciard Cyril, Allesandro Fedrizzi, Weinhold J. Till, Adriana Lita, Brice R. Calkins, Thomas Gerrits, Wiseman H, Sae Woo Nam, Andrew G. White
Quantum steering allows two parties to verify shared entanglement even if one measurement device is untrusted. A conclusive demonstration of steering through the violation of a steering inequality is of considerable fundamental interest and opens up

Integration is currently the only feasible route towards scalable photonic quantum processing devices which are sufficiently complex to be genuinely useful in computing, metrology, and simulation. Embedded on-chip detection will be critical to such devices
