Quantum backaction evading measurements of a silicon nitride membrane resonator
نویسندگان
چکیده
Quantum backaction disturbs the measurement of position a mechanical oscillator by introducing additional fluctuations. In quantum technique, can be evaded, although at cost losing part information. this work, we carry out such using large 0.5 mm diameter silicon nitride membrane with 707 kHz frequency, via microwave cavity readout. The shows that noise evaded in quadrature motion object.

Quantum Backaction Evading Measurement of Collective Mechanical Modes.
The standard quantum limit constrains the precision of an oscillator position measurement. It arises from a balance between the imprecision and the quantum backaction of the measurement. However, a measurement of only a single quadrature of the oscillator can evade the backaction and be made with arbitrary precision. Here we demonstrate quantum backaction evading measurements of a collective qu...
متن کاملPiezoelectrically tuned silicon nitride ring resonator
Typical integrated optical phase tuners alter the effective index. In this paper, we explore tuning by geometric deformation. We show that tuning efficiency, VπL, improves as the device size shrinks down to the optimal bend radius, contrary to conventional index-shift based approaches where VπL remains constant. We demonstrate that this approach is capable of ultra-low power tuning across a ful...
متن کاملHigh confinement micron-scale silicon nitride high Q ring resonator.
We demonstrate high confinement, low-loss silicon nitride ring resonators with intrinsic quality factor (Q) of 3*10(6) operating in the telecommunication C-band. We measure the scattering and absorption losses to be below 0.065dB/cm and 0.055dB/cm, respectively.
متن کاملQuantum electromechanics on silicon nitride nanomembranes
Radiation pressure has recently been used to effectively couple the quantum motion of mechanical elements to the fields of optical or microwave light. Integration of all three degrees of freedom-mechanical, optical and microwave-would enable a quantum interconnect between microwave and optical quantum systems. We present a platform based on silicon nitride nanomembranes for integrating supercon...

In this proposal we seek to establish a porous silicon based etching process in the WTC microfabrication laboratory. The new process will allow us to etch high aspect ratio holes through a wafer. Holes like these are important for decreasing the dead volume of connections between micro and macro systems and for increasing the complexity of micro-fluidic systems. At the present time, the minimum...
