Generation and Frequency Conversion of Quantum States in high "Q" SRF Parametric Oscillators
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 input/output 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.
