Designing QHC simple logic gates, half-adder and majority gates circuit on a Si(100)-H surface

Belonging to the Quantum Hamiltonian Computing (QHC) branch of quantum
control [1-2], atomic-scale Boolean logic gates (LGs) with two inputs - one output
(OR, NOR, AND, NAND, XOR, NXOR) and - two outputs (half-adder circuit) were
designed on a Si(100)-(2× 1)-H surface following the experimental realization of a
QHC NOR gate [3] and the formal design of an half-adder with 6 quantum states in
the calculating block [4]. The logical inputs are determined by two nearest neighbor crossing surface Si dan ...

Violation of the Second Law of Thermodynamics and its Consequences

School
PARTICLES AND ACCELERATORS

A reason that we never observe the violation of the second law of thermodynamics in our everyday life lies, in part, in an emergent property came out of a huge number of degrees of freedom of order Avogadro's number. That's why e.g., a resistance never injects energy back into an electric circuit. In small systems in turn, statistical fluctuations are dominant and play a crucial role to describe the statistical behavior of the systems far from equilibrium. In this talk, after a fast review of the non-equilibrium thermodynamics, we will show an example in which the second law can be violated, and this violation interestingly provides some usef ...
