Physical Limits to Computation

Computers and clocks are physical systems. As such, they must obey the laws of physics. [1] Here we show that both the speed with which a computer can process information and the amount of information that it can process are limited by the input power. In particular, their product is bounded by a universal constant. As a prelude, we show that the maximum time that a clock remains accurate is li...

0 Physical limits to computation

Computers and clocks are physical systems. As such, they must obey the laws of physics. [1] Here we show that, according to the laws of quantum mechanics and gravitation, both the speed ν with which a computer can process information and the amount of information I that it can process are limited by the input power. In particular, their product is bounded by a universal constant given by Iν <∼ ...

Physical limits of computation and emergence of life

The computational process is based on the activity linking mathematical equations to a materialized physical world. It consumes energy which lower limit is defined by the set of Planck's values, i.e. by the physical structure of the Universe. We discuss computability from the quantum measurement framework. Effective quantum computation is possible via the maintenance of a long-living cold decoh...

Physical limits of inference

We show that physical devices that perform observation, prediction, or recollection share an underlying mathematical structure. We call devices with that structure “inference devices”. We present a set of existence and impossibility results concerning inference devices. These results hold independent of the precise physical laws governing our universe. In a limited sense, the impossibility resu...
