A quantum photonic imaging device used in an underwater vehicle for stealthy detection of underwater objects includes a photon generating module that generates an entangled pair of photons that includes a signal photon and an ancilla photon, wherein the ancilla photon is retained within the device; a transmitter that transmits the signal photon towards a region of space for detecting an underwater object; a receiver that detects an incoming photon to the device; and a correlation module that distinguishes the signal photon that is reflected back to the receiver due to a presence of the object from environmental noise photons, wherein the distinguishing includes determining an entanglement correlation of the detected photon with the ancilla photon, and wherein a presence of the entanglement correlation between the detected photon and the ancilla photon indicates that the detected photon is the signal photon reflected back from the object.
