Narrow-band Multi-photon Source for Quantum Information Applications

A novel and easy to implement method to generate narrow-band (~ 10 MHz bandwidth) multi-photon states using cavity enhanced spontaneous parametric down-conversion (CE-SPDC) Background The generation of narrow-band single and multi-photon states with a long coherence length is an important step for reliable quantum applications. Technology Applications Quantum...

A method of probabilistic one time programs with information theoretic security

To combat software piracy, various safety checks can be built into computer programs. One such method is that of “one-time” programs which can only be executed a single time. By the use of this quantum technology, a classical program can be only allowed to operate a single time, preventing copying of the software.Researchers at the University...

A rational functions approach to BWIM and data storage

Vehicle overloading is a significant factor in the degradation of road surfaces. The analysis of sensor data is particularly complicated when dealing with multiple parallel lanes and vehicles with many axles.The algorithm enables the signals received by WIM sensors to be assigned correctly to individual axles and axle groups, even when parallel moving...

Quantum Imaging with undetected photons

Low light detectors, for example those used in cameras only operate at certain frequencies / wavelengths. Outside of these wavelengths they become inefficient and for certain wavelengths commercial available detectors may not function at all. However the material properties or dimensions of the item to be imaged dictate the optimal wavelength. An imagining...
