Computing By A Black Hole!?

I have recently read the november edition of Scientific American.
The article says that everything computes.
Bits like momentum ,angular momentum exchange when particles interact with each other.
But how does it encode matters as quantum mechanics effect exists?I can't really be certain of particles momentum and position.
And more professionally do black holes output information we need?And according to which theory?
And then WHY we don't just put matters into an ordinary matter ?Black holes have any specific property?

black holes by definitions perform chaotic computations in planck-time at Beckenstein's bound-

I have been very intrigued of late that according to Seth lloyd the observable universe represents 10^90 bits of information and the universe has performed 10^120 operations since the Big Bang [ http://www.kurzweilai.net/meme/frame.html?main=/articles/art0530.html [Broken] ] given the computational nature of Black Holes- the average supermassive type black hole could easily nmake computations of this magnitude and beyond - the information density of a black hole is by definition at the Beckenstein Bound of 10^66 bits per sq cm- a super massive black hole has a radius of around 10^9 km- which makes the surface area around 10^19 sq km- with 10^66 bits per sq cm- the black hole stores 10^76 bits per sq km- that is.... 10^95 BITS total! [remember the universe is 10^90 bits]- and a supermassive black hole lasts for googolplexes of aeons- yet performs operations at Planck time- 10^43 flops per second [therefore processing 10^138 bits/sec] and will keep calculating at this rate for near eternity- as you can see- a supermassive Black hole CAN compute universes like ours quite comfortably indeed- in fact the entire history of our universe could be calculated within one-quintillionth [10^-18] of a second! hmmmmmm

it is also promising to think what may be possible with computation if we are succesfully able to create artificial microscale black holes at the LHC-future computers might make unfathomably vast computaions with the brief poof of hawking radiation from the rapid evaporation of networks of microscale black holes
