Abstract:
Major Goals Phase I is an 18-month effort with a budget of 200,000 to evaluate the expected performance of such a scheme and to demonstrate squeezing of RF fields. The key tasks are 1 Quantify the oscillation threshold for a degenerate parametric oscillator in terms of cavity Q, and frequency of operation. 2 Quantify the fundamental and practical limits to squeezing in such a device. 3 Determine the merits and drawbacks of quadrature squeezing in a degenerate scheme vs. two-mode squeezing in a nondegenerate scheme. 4 Implement an experimental apparatus for squeezing generation at microwave frequencies. 5 Implement an experimental apparatus for squeezing measurements at microwave frequencies. 6 Quantify the fundamental and practical limits associated with the fidelity of transferring the squeezed state from microwave to optical frequencies. The 6 tasks listed above fall into 3 categories 1 SRF cavity design, fabrication and test we will build one prototype and then a second SRF cavity 2 measurement apparatus design, implementation and test and 3 theoretical support. Phase II is an additional 18-month effort with a budget of 200,000 to demonstrate the frequency conversion of squeezed RF fields to optical frequencies. The key tasks are 1 Implement optical inputoutput access to the dilution refrigerator and implement an optical channel for Doppler shifting of the optical field in the presence of the moving SRF cavity membrane. 2 Implement and test the optical squeezing characterization circuit. 3 Quantify the efficiency of squeezing translation in such a device.
