A titanium-nitride near-infrared kinetic inductance photon-counting detector and its anomalous electrodynamics

Complete quantum teleportation with a kerr nonlinearity

We present a scheme for the quantum teleportation of the polarization state of a photon employing a cross-Kerr medium. The experimental feasibility of the scheme is discussed and we show that, using the recently demonstrated ultraslow light propagation in cold atomic media, our proposal can be realized with presently available technology.

Multiplexable Kinetic Inductance Detectors

We are starting to investigate a novel multiplexable readout method that can be applied to a large class of superconducting pair-breaking detectors. This readout method is completely different from those currently used with STJ and TES detectors, and in principle could deliver large pixel counts, high sensitivity, and Fano-limited spectral resolution. The readout is based on the fact that the k...

Thermal stability of a-titanium in contact with titanium nitride

The thermal stability of an a-Ti film in contact with a d-TiN film in the structure of a TiN/Ti/TiN film stack on SiO2 substrates was studied by in situ sheet resistance (Rs) measurement, Auger electron spectroscopy, glancing angle x-ray diffractometry, cross-sectional transmission electron microscopy, scanning electron microscopy, and atomic force microscopy. It was found that nitrogen dissolv...

Measurement-Induced Strong Kerr Nonlinearity for Weak Quantum States of Light.

Strong nonlinearity at the single photon level represents a crucial enabling tool for optical quantum technologies. Here we report on experimental implementation of a strong Kerr nonlinearity by measurement-induced quantum operations on weak quantum states of light. Our scheme coherently combines two sequences of single photon addition and subtraction to induce a nonlinear phase shift at the si...
