On the Speed-up of Wave-like Dark Matter Searches with Entangled Qubits
Arushi Bodas, Sohitri Ghosh, Roni Harnik
Qubit-based sensing platforms offer promising new directions for wave-like dark matter searches. Recent proposals demonstrate that entangled qubits can achieve quadratic scaling of…
Listening For New Physics With Quantum Acoustics
Ryan Linehan, Tanner Trickle, Christopher R. Conner +4
We present a novel application of a qubit-coupled phonon detector to search for new physics, e.g., ultralight dark matter (DM) and high-frequency gravitational waves. The detector,…
A general approach to backaction-evading receivers with magnetomechanical and electromechanical sensors
Brittany Richman, Sohitri Ghosh, Daniel Carney +4
Today's mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both…
Combining quantum noise reduction resources: a practical approach
Sohitri Ghosh, Matthew A. Feldman, Seongjin Hong +4
Optomechanical sensors are capable of transducing external perturbations to resolvable optical signals. A particular regime of interest is that of high-bandwidth force detection, w…
Snowmass 2021 White Paper: The Windchime Project
The Windchime Collaboration, Alaina Attanasio, Sunil A. Bhave +23
The absence of clear signals from particle dark matter in direct detection experiments motivates new approaches in disparate regions of viable parameter space. In this Snowmass whi…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
Back-action evading impulse measurement with mechanical quantum sensors
Sohitri Ghosh, Daniel Carney, Peter Shawhan +1
The quantum measurement of any observable naturally leads to noise added by the act of measurement. Approaches to evade or reduce this noise can lead to substantial improvements in…
Proposal for gravitational direct detection of dark matter
Daniel Carney, Sohitri Ghosh, Gordan Krnjaic +1
The only coupling dark matter is guaranteed to have with the standard model is through gravity. Here we propose a concept for direct dark matter detection using only this gravitati…
