(DURIP) QUANTUM COHERENCE AND QUANTUM INTERACTIONS IN MICROTUBULES AND SURROUNDING ENVIRONMENT
Abstract
This proposal requests funding for a state-of-the-art system for quantum optical spectroscopy, sensing and imaging. Specifically we are requesting funds to purchase a new laser source composed of a single-frequency intracavity doubled Nd:YVO4 laser (M2-EQ10; M Squared Lasers, Inc.) which pumps a single-frequency broadly tunable Ti:sapphire laser (SolsTiS SA PSX XF; M Square Lasers, Inc). Both lasers possess laser linewidth of less than 100-kHz with the average power of 10-W for the 532-nm laser and 2-W for the Ti:sapphire laser. The wavelength of both lasers is stabilized to ensure long-term stability and reproducibility of the laser output. The second component of the system is a quantum measurement system (Boston Electronics, Inc.), which is composed of a single-photon superconducting nanowire detector (8 channels, independently addressable) coupled to a multichannel time-correlating photon-counting system for high fidelity, high temporal resolution, high-sensitivity correlation quantum measurements. The design of superconducting nanowires allows fine tuning for peak quantum efficiency anywhere from ultraviolet to near-infrared (up to 2200 nm). The combination of the best singlefrequency source at two distinct wavelength regions (532 nm and 750-950 nm) and the best singlephoton detector makes the proposed system unique and will allow us to perform quantum spectroscopy, sensing and imaging experiments with sensitivity and accuracy, which are not currently possible in our laboratories.
