Perimeter Security Detection System Based on Piezoelectric Strain Measurement
A system is described that uses force-plate-mounted piezoelectric strain measurement to detect and quantify pedestrian traffic. The system uses distributed piezoelectric sensors in a stiff structural platform and is combined with a sensing and counting circuit. The paper describes the application of this technology for monitoring pedestrian traffic on a municipal trail. The application of the s...
متن کاملQuantum dot single-photon switches of resonant tunneling current for discriminating-photon-number detection
Low-noise single-photon detectors that can resolve photon numbers are used to monitor the operation of quantum gates in linear-optical quantum computation. Exactly 0, 1 or 2 photons registered in a detector should be distinguished especially in long-distance quantum communication and quantum computation. Here we demonstrate a photon-number-resolving detector based on quantum dot coupled resonan...
متن کاملQuantum random number generator based on homodyne detection
The need to generate random numbers arises in many scientific and engineering disciplines. There are many types of random number generators with different entropy sources. Historically, two approaches for random number generation have been developed. According to the first method, random numbers can be generated algorithmically, but the resulting sequences in that case are pseudorandom and not ...

متن کاملOn the Optimal Mean Photon Number for Quantum Cryptography
The optimal mean photon number (μ) for quantum cryptography is the average photon number per transmitted pulse that results in the highest delivery rate of distilled cryptographic key bits, given a specific system scenario and set of assumptions about Eve’s capabilities. Although many experimental systems have employed a mean photon number (μ) of 0.1 in practice, several research teams have poi...
