Query: Augmenting the Sensing Performance of Entangled Photon Pairs through
  Asymmetry   We analyze theoretically and experimentally cases of asymmetric detection,
stimulation, and loss within a quantum nonlinear interferometer of entangled
pairs. We show that the visibility of the SU(1,1) interference directly
discerns between loss on the measured mode (signal) and the conjugated mode
(idler). This asymmetry also affects the phase sensitivity of the
interferometer, where coherent seeding is shown to mitigate losses that are
suffered by the conjugated mode; therefore increasing the maximum threshold of
loss that permits sub-shot-noise phase detection. Our findings can improve the
performance of setups that rely on direct detection of entangled pairs, such as
quantum interferometry and imaging with undetected photons.
