Heisenberg-limited metrology with information recycling
Simon A. Haine, Stuart S. Szigeti, Matthias D. Lang +1
Information recycling has been shown to improve the sensitivity of atom interferometers by exploiting atom-light entanglement. In this paper, we apply information recycling to an i…
Squeezed-light-enhanced atom interferometry below the standard quantum limit
Stuart S. Szigeti, Behnam Tonekaboni, Wing Yung S. Lau +2
We investigate the prospect of enhancing the phase sensitivity of atom interferometers in the Mach-Zehnder configuration with squeezed light. Ultimately, this enhancement is achiev…
Ignorance is bliss: General and robust cancellation of decoherence via no-knowledge quantum feedback
Stuart S. Szigeti, Andre R. R. Carvalho, James G. Morley +1
A "no-knowledge" measurement of an open quantum system yields no information about any system observable; it only returns noise input from the environment. Surprisingly, performing…
