Quantum Chips Can Cracks Code

Current cryptography relies on factoring huge numbers where modern computers have difficultly to efficiently complete the task. Now, researchers find using Shor's Algorithm (based on nuclear magnetic resonance ) for first factoring in a chip scale quantum computer maybe practical on code cracking and quantum computing. Since a quantum computer uses a qubit, it makes it exponentially faster to solve problems like factoring (allowing the computer to test more solutions at a time) Although quantum factoring machine is decades away, chip-scale optical architectures can help in applications like quantum key distribution or simulate quantum systems in physics experiments.

Sensitivity Infrared Spectrometry with Frequency Converter

Researchers at the National Institute of Standards and Technology (NIST) have developed a new, highly sensitive, low-cost technique for measuring light near the infrared range. A single photon detector is the key device needed to build highly sensitive instruments for measuring spectra. Their approach is adapting a technique developed two years ago at NIST for quantum cryptography that “up converts” photons at one frequency to a higher frequency. The technique promotes the infrared photons up to the visible range using a strong, tunable laser.
