Scalable Ion Fluorescence Collection Using a Trap-Integrated Metalens
Hae Lim, Johannes E. Fröch, Christian M. Pluchar +2
A scaled trapped-ion quantum computer will require efficient fluorescence collection across a large area. Here we propose and demonstrate a compact monolithically integrated system…
Ultrahigh-Q Torsional Nanomechanics through Bayesian Optimization
Atkin D. Hyatt, Aman R. Agrawal, Christian M. Pluchar +2
Recently it was discovered that torsion modes of strained nanoribbons exhibit dissipation dilution, giving a route to enhanced torque sensing and quantum optomechanics experiments.…
Quantum limited imaging of a nanomechanical resonator with a spatial mode sorter
Morgan Choi, Christian Pluchar, Wenhua He +2
We explore the use of a spatial mode sorter to image a nanomechanical resonator, with the goal of studying the quantum limits of active imaging and extending the toolbox for optome…
Ultralow loss torsion micropendula for chipscale gravimetry
C. A. Condos, J. R. Pratt, J. Manley +4
We explore a new class of chipscale torsion pendula formed by SiN nanoribbon suspensions. Owing to their unique hierarchy of gravitational, tensile, and elastic stiffness,…
Quantum-limited optical lever measurement of a torsion oscillator
Christian M. Pluchar, Aman R. Agrawal, Dalziel J. Wilson
The optical lever is a precision displacement sensor with broad applications. In principle, it can track the motion of a mechanical oscillator with added noise at the Standard Quan…
Imaging-based Quantum Optomechanics
Christian M. Pluchar, Wenhua He, Jack Manley +3
In active imaging protocols, information about an object is encoded into the spatial mode of a scattered photon. Recently the quantum limits of active imaging have been explored wi…
Thermal intermodulation backaction in a high-cooperativity optomechanical system
Christian M. Pluchar, Aman R. Agrawal, Dalziel J. Wilson
The pursuit of room temperature quantum optomechanics with tethered nanomechanical resonators faces stringent challenges owing to extraneous mechanical degrees of freedom. An impor…
Entanglement-Enhanced Optomechanical Sensing
Yi Xia, Aman R. Agrawal, Christian M. Pluchar +5
Optomechanical systems have been exploited in ultrasensitive measurements of force, acceleration, and magnetic fields. The fundamental limits for optomechanical sensing have been e…
Membrane-based Optomechanical Accelerometry
Mitul Dey Chowdhury, Aman R. Agrawal, Dalziel J. Wilson
Optomechanical accelerometers promise quantum-limited readout, high detection bandwidth, self-calibration, and radiation pressure stabilization. We present a simple, scalable platf…
Nanoscale torsional dissipation dilution for quantum experiments and precision measurement
Jon R. Pratt, Aman R. Agrawal, Charles A. Condos +3
We show that torsion resonators can experience massive dissipation dilution due to nanoscale strain, and draw a connection to a century-old theory from the torsion balance communit…
Towards cavity-free ground state cooling of an acoustic-frequency silicon nitride membrane
Christian M. Pluchar, Aman Agrawal, Edward Schenk +1
We demonstrate feedback cooling of a millimeter-scale, 40 kHz SiN membrane from room temperature to 5 mK (3000 phonons) using a Michelson interferometer, and discuss the challenges…
