Optimal encoding of oscillators into more oscillators
Jing Wu, Anthony J. Brady, Quntao Zhuang
Bosonic encoding of quantum information into harmonic oscillators is a hardware efficient approach to battle noise. In this regard, oscillator-to-oscillator codes not only provide…
Robustness of entanglement in Hawking radiation for optical systems immersed in thermal baths
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
Entanglement is the quantum signature of Hawking's particle pair-creation from causal horizons, for gravitational and analog systems alike. Ambient thermal fluctuations, ubiquitous…
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…
Entanglement-enhanced optomechanical sensor array for dark matter searches
Anthony J. Brady, Xin Chen, Kewen Xiao +8
The nature of dark matter is one of the most important open questions in modern physics. The search for dark matter is challenging since, besides gravitational interaction, it feeb…
Global Time Distribution via Satellite-Based Sources of Entangled Photons
Stav Haldar, Ivan Agullo, Anthony J. Brady +3
We propose a satellite-based scheme to perform clock synchronization between ground stations spread across the globe using quantum resources. We refer to this as a quantum clock sy…
Symplectic circuits, entanglement, and stimulated Hawking radiation in analog gravity
Anthony J. Brady, Ivan Agullo, Dimitrios Kranas
We introduce a convenient set of analytical tools (the Gaussian formalism) and diagrams (symplectic circuits) to analyze multi-mode scattering events in analog gravity, such as pai…
Event horizons are tunable factories of quantum entanglement
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
That event horizons generate quantum correlations via the Hawking effect is well known. We argue, however, that the creation of entanglement can be modulated as desired, by appropr…
Searches for New Particles, Dark Matter, and Gravitational Waves with SRF Cavities
Asher Berlin, Sergey Belomestnykh, Diego Blas +33
This is a Snowmass white paper on the utility of existing and future superconducting cavities to probe fundamental physics. Superconducting radio frequency (SRF) cavity technology…
Entangled sensor-networks for dark-matter searches
Anthony J. Brady, Christina Gao, Roni Harnik +3
The hypothetical axion particle (of unknown mass) is a leading candidate for dark matter (DM). Many experiments search for axions with microwave cavities, where an axion may conver…
Enhancing distributed sensing with imperfect error correction
Boyu Zhou, Anthony J. Brady, Quntao Zhuang
Entanglement has shown promise in enhancing information processing tasks in a sensor network, via distributed quantum sensing protocols. As noise is ubiquitous in sensor networks,…
