Squeezing Towards the Heisenberg Limit with Locally Interacting Spins
Nazli Ugur Koyluoglu, Shankari V. Rajagopal, Gabriel L. Moreau +3
We propose a robust approach to spin squeezing with local interactions that approaches the Heisenberg limit of phase sensitivity. To generate the requisite entanglement, we general…

Signal amplification in a solid-state quantum sensor via asymmetric time-reversal of many-body dynamics
Haoyang Gao, Leigh S. Martin, Lillian B. Hughes +8
Electronic spins of nitrogen vacancy (NV) centers in diamond constitute a promising system for micro- and nano-scale magnetic sensing, due to their operation under ambient conditio…
