Controllable quantum systems are heralding a quantum technology revolution.
By coupling controllable quantum systems into larger structures we introduce
the concept of a quantum metamaterial. Conventional metamaterials represent one
the most important frontiers in optical design, with applications in diverse
fields ranging from medicine to aerospace. Up until now however, metamaterials
have themselves been classical structures and interact only with the classical
properties of light. Here we describe a class of dynamic metamaterials, based
on the quantum properties of coupled atom-cavity arrays, which are
intrinsically lossless, reconfigurable, and operate fundamentally at the
quantum level. We show how this new class of metamaterial could be used to
create a reconfigurable quantum superlens possessing a negative index gradient
for single photon imaging. With the inherent features of quantum superposition
and entanglement of metamaterial properties, this new class of dynamic quantum
metamaterial, opens a new ista for quantum science and technology.
