Quantum Noise, Coherence, and Sensing
Abstract
Quantum informatics, e.g., quantum computing, searching, and sensing, etc. is evolving into a real world tool. Quantum noise suppression techniques which can enhance quantum coherence and minimize decoherence are the key to further development. While such quantum devices will come with different hardware platforms, such as superconductors, semiconductors, ion traps, or atoms, the only way to transmit quantum states over large distances will be with photons.The targeted outcome is quantum systems development, and this will stimulate research in quantum information processing and quantum communication, e.g., networks as well as sensing and metrology applications by making materials and hybrid structures for experimental tests and development of quantum technologies more available.We emphasize that in addition to being a platform for distributed quantum computing, quantum optical networks it will form a backbone for improvement in distributed quantum sensors. A quantum sensor is a device that exploits quantum states such as coherent states, entangled states or squeezed states in order to improve signal to noise beyond the classical limit of sensitivity. Suchsensors have been demonstrated or proposed in improved atomic clocks, magnetometers, polarization measurements, gravitational wave detection, gyroscopes, chemical and biological sensors, and improved imaging systems such as microscopes and very large synthetic aperture telescope arrays.DOD relevance is obvious; we should push to bring quantum informatics to the real world. It is already in the laboratory and there exist proof-of-principle experiments, e.g., the Chinese quantum communication (by the BB84 protocol) from China to Austria. Our proposed study of injected coherence and noise induced coherence is very relevant to such studies. The TAMUIQSEis a strong player in this field and will work toward pushing the envelope.The two main parts of our proposed scientific program include: 1) Noise suppression in systems involving arrays of photonic cavities and fibers with precisely positioned nanoparticles and molecules; and 2) Quantum topological effects, quantum devices and networking using quantum materials, coherence and entanglement platforms. We also plan to continue to be active in thefield of theoretical quantum statistical mechanics.
