Quantum Imaging and Information

Abstract (Summary)

Quantum optics provides a unique avenue to investigate quantum mechanical effects. Typically, it is easier to observe the particle-like behavior of a physical object than it is to observe wave-like behavior. Optics presents us with the reverse case, observing the particle-like behavior of light is difficult. I investigate the utility and limitations of two quantum mechanical effects—weak values and spatial entanglement—in the context of experimental quantum optical communication channels. I show that weak values can be used to increase the signal power and effectively decrease the noise power in a physical communication channel, up to the standard quantum limit for signal to noise ratio. I also show show a method for decreasing the negative environmental effects on a communication channel using spatial entanglement and show that such a channel can be used to transmit over 7 bits of information per joint photon detection event.
