Surpassing the Standard Quantum Limit using an Optical Spring
Torrey Cullen, Scott Aronson, Ron Pagano +9
Quantum mechanics places noise limits and sensitivity restrictions on physical measurements. The balance between unwanted backaction and the precision of optical measurements impos…
Design of Microresonators to Minimize Thermal Noise Below the Standard Quantum Limit
Safura Sharifi, Yaser Banadaki, Torrey Cullen +3
We present a design for a new microresonator whose geometry is optimized to maximize sub-Standard Quantum Limit (SQL) performance. The new design is predicted to have thermal noise…
Quantum back action cancellation in the audio band
Jonathan Cripe, Torrey Cullen, Yanbei Chen +4
We report on the cancellation of quantum back action noise in an optomechanical cavity. We perform two measurements of the displacement of the microresonator, one in reflection of…
Room temperature optomechanical squeezing
Nancy Aggarwal, Torrey Cullen, Jonathan Cripe +7
The radiation-pressure driven interaction of a coherent light field with a mechanical oscillator induces correlations between the amplitude and phase quadratures of the light. Thes…
