The amount of heat generated by computers is rapidly becoming one of the main problems
for develo** new generations of information technology. The thermodynamics of …

We describe a quantum mechanical heat engine. Like its classical counterpart introduced by
Carnot, this entine carries out a reversible process in which an input of energy to the system …

Finding ground states of quantum many-body systems is known to be hard for both classical
and quantum computers. As a result, when Nature cools a quantum system in a low …

We argue that the halting problem for quantum computers which was first raised by Myers, is
by no means solved, as has been claimed recently. We explicitly demonstrate the difficulties …

Landauer's principle laid the main foundation for the development of modern
thermodynamics of information. However, in its original inception the principle relies on …

Imagine a computer whose memory is exponentially larger than its apparent physical size; a
computer that can manipulate an exponential set of inputs simultaneously; a computer that …

The third law of thermodynamics, also known as the Nernst unattainability principle, puts a
fundamental bound on how close a system, whether classical or quantum, can be cooled to …

We investigate the time T a quantum computer requires to factorize a given number
dependent on the number of bits L required to represent this number. We stress the fact that …

In the popular imagination, quantum computers would be almost magical devices, able to
“solve impossible problems in an instant” by trying exponentially many solutions in parallel …
