At <strong>Atom</strong> shot-noise h t i limits li it sensor per<strong>for</strong>mance.<br />
f<br />
Recently evolving ideas in quantum in<strong>for</strong>mation science have<br />
provided a road-map to exploit exotic quantum states to significantly<br />
enhance sensor per<strong>for</strong>mance.<br />
– Sensor noise scales as 1/N where N is the number of particles<br />
– “Heisenberg” Heisenberg limit<br />
– Shot-noise ~ 1/N1/2 limits existing sensors<br />
Challenges:<br />
– Demonstrate basic methods in laboratory<br />
– Begin to address engineering tasks <strong>for</strong> realistic sensors<br />
Impact of successful implementation <strong>for</strong> practical position/time<br />
sensors could be substantial.<br />
