Enhancing Sensitivity of an Atom Interferometer to the Heisenberg Limit using Increased Quantum Noise

Renpeng Fang, Resham Sarkar, Selim M. Shahriar

In a conventional atomic interferometer employing $N$ atoms, the phase sensitivity is at the standard quantum limit: $1/\sqrt{N}$. Using spin-squeezing, the sensitivity can be incr…
