Future technology: Quantum Metrology<br />

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 />
