Macroscopic tunneling of a membrane in an optomechanical double-well potential
L. F. Buchmann, L. Zhang, A. Chiruvelli +1
The macroscopic tunneling of an optomechanical membrane is considered. A cavity mode which couples quadratically to the membranes position can create highly tunable adiabatic doubl…
Quantum Metrology with Two-Mode Squeezed Vacuum: Parity Detection Beats the Heisenberg Limit
Petr M. Anisimov, Gretchen M. Raterman, Aravind Chiruvelli +4
We study the sensitivity and resolution of phase measurement in a Mach-Zehnder interferometer with two-mode squeezed vacuum (<n> photons on average). We show that super-resolution…
Parity Measurements in Quantum Optical Metrology
Aravind Chiruvelli, Hwang Lee
We investigate the utility of parity detection to achieve Heisenberg-limited phase estimation for optical interferometry. We consider the parity detection with several input states…
Canonical Phase Measurements in the Presence of Photon Loss
Aravind Chiruvelli, Hwang Lee
We analyze the optimal state, as given by Berry and Wiseman [Phys. Rev. Lett {\bf 85}, 5098, (2000)], under the canonical phase measurement in the presence of photon loss. The mode…
Rapid-purification protocols for optical homodyning
Aravind Chiruvelli, Kurt Jacobs
We present a number of rapid-purification feedback protocols for optical homodyne detection of a single optical qubit. We derive first a protocol that speeds up the rate of increas…
Mesoscopic superposition and sub-Planck-scale structure in molecular wave packets
Suranjana Ghosh, Aravind Chiruvelli, J. Banerji +1
We demonstrate the possibility of realizing sub-Planck-scale structures in the mesoscopic superposition of molecular wave packets involving vibrational levels. The time evolution o…
