Linearized analysis of dissipative Two Axis Counter Twisting (TACT) squeezing for Metrology
Garry Goldstein
In this work we analyze two axis twisting in the presence of depolarizing channel dissipation. We find that spin squeezing is only possible if the dissipation is parametrically wea…

One Axis Twisting (OAT) spin squeezing for metrology
Garry Goldstein
In this work we study One Axis Twisting (OAT) spin squeezing for metrology in the presence of decoherence. We study Linbladian evolution in the presence of both T_1 and T_2 (longit…

Environment Assisted Precision Measurement
G. Goldstein, P. Cappellaro, J. R. Maze +4
We describe a method to enhance the sensitivity of precision measurements that takes advantage of a quantum sensor's environment to amplify its response to weak external perturbati…
