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...

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 <∼ ...

By reading, you can know the knowledge and things more, not only about what you get from people to people. Book will be more trusted. As this formal models of computation the ultimate limits of computing, it will really give you the good idea to be successful. It is not only for you to be success in certain life you can be successful in everything. The success can be started by knowing the basi...
متن کاملQuantum Computation—The Ultimate Frontier
The discovery of an algorithm for factoring which runs in polynomial time on a quantum computer has given rise to a concerted effort to understand the principles, advantages, and limitations of quantum computing. At the same time, many different quantum systems are being explored for their suitability to serve as a physical substrate for the quantum computer of the future. I discuss some of the...
متن کاملPhysical limits to magnetogenetics
This is an analysis of how magnetic fields affect biological molecules and cells. It was prompted by a series of prominent reports regarding magnetism in biological systems. The first claims to have identified a protein complex that acts like a compass needle to guide magnetic orientation in animals (Qin et al., 2016). Two other articles report magnetic control of membrane conductance by attach...
