Quantum enhancement to information acquisition speed

Abstract The speed of the transmission a physical signal from sender to receiver is limited by light, regardless system being classical or quantum. In this sense, quantum mechanics can not provide any enhancement information transmission. If instead we consider that needing be transmitted localized at sender’s location, but dispersed throughout space, spatial coherence might some enhancement. work, demonstrate mechanical advantage in acquirement and globally encoded space. We present task for which prove quadratic acquisition using carriers with respect their counterpart. Our findings naturally applied situations where source has power, i.e. bounded number signals sent per unit time.
