Optical gain in silicon nanocrystals
... follow a straight line with a slope j < 3 3 10 2 16 cm2 . The intercept of the ®tted straight line with the vertical axis gives the lifetime of the Si nanocrystals in the system at the measured wavelength. The obtained value (70 ms) is in agreement with decay time measurements at 850 nm on the same ...

The informational statement is that we can sometimes be more certain about the joint state of a quantum system than we can be about any one of its individual parts, and this is the reason that conditional quantum entropy can be negative. This is in fact the same observation ...

However, this optimisation of similarity will not increase the rate of information transmission at all. This illustrates the ...
