Supraclassical measurement using single-atom control of an atomic ensemble
Supraclassical measurement using single-atom control of an atomic ensemble
We analyze the operation of a novel sensor based on atom interferometry, which can achieve supra-classical sensitivity by exploiting quantum correlations in mixed states of many qubits. The interferometer is based on quantum gates which use coherently-controlled Rydberg interactions between a single atom (which acts as a control qubit) and …
