#1 La clave entiendo que sería en la densidad de la información que se transmite.
Ahora se identifica la información por la frecuencia del haz, las intermitencias, etc.
En este caso dicen haber conseguido dar forma y leer la forma de un único foton. La densidad de información que se podría transmitir con esto es abrumadora.
"A pulse of light can have almost any shape in space and in time, determined by the amplitudes and phases of its frequency components. Surprisingly, single photons can also be generated in a variety of complex shapes. The difference is that the amplitude for a single photon doesn’t represent a definite value of the electric field strength; instead it’s associated with the probability of detecting the photon at each location and time.
Researchers could also encode information in the photon shape and transmit it from one place to another. There is so much flexibility that a SINGLE photon could represent any letter in the alphabet, for example, or even a quantum combination (superposition) of several letters. But the detection system must be able to distinguish, say, the letter P from the letter Q, even after the photon has been distorted during the trip from the transmitter".

Los 32Mb/día de ancho de banda del Curiosity parecen un chiste viedo las posibilidades de esto.
El algoritmo de lectura deja mucho que desear. Va probando formas hasta que hay una que coincide.
Ya se transmite información usando la luz, ¿no?

#1 Con pulsos de luz, si.
