"... This is a brief overview of quantum holonomies in the context of quantum computation. We choose an adequate set of quantum logic gates, namely, a phase gate, the Hadamard gate, and a conditionalphase gate and show how they can be implemented by purely geometric means. Such gates may be more resilie ..."

Molecular NOR logic gate
"... Abstract. Molecular computing created for implementing logic systems, solving NPdifficult problems on nanoscale depends on DNA selfassembly abilities and on modifying DNA with the help of enzymes during genetic operations. In the typical DNA computing a sequence of operations executed on DNA molec ..."

to implementation of OR, NOR logic gates on molecules. It requires the representation of signals by DNA molecules. The presented method allows for constructing logic gates with many inputs and for executing them at the same quantity of elementary operations, regardless of a number of input signals. The NOR gate

Multivalued logic gates for quantum computation
 Phys. Rev. A
, 2000
"... We develop a multivalued logic for quantum computing for use in multilevel quantum systems, and discuss the practical advantages of this approach for scaling up a quantum computer. Generalizing the methods of binary quantum logic, we establish that arbitrary unitary operations on any number of dl ..."

level systems (d Ͼ2) can be decomposed into logic gates that operate on only two systems at a time. We show that such multivalued logic gates are experimentally feasible in the context of the linear ion trap scheme for quantum computing. By using d levels in each ion in this scheme, we reduce the number of ions
On Universality of Ternary Reversible Logic Gates

A set of pvalued logic gates (primitives) is called universal if an arbitrary pvalued logic function can be realized by a logic circuit built up from a finite number of gates belonging to this set. In the paper, we consider the problem of determining the number of universal ternary reversible logi ..."

"... In classical computer, there exist inevitable demerits for discussing logical gates. One of the demerits is an irreversibility of logical gates, that is the AND and the OR gates. This property causes to the restriction of computtional speed for the classical computer. $\mathrm{T}\mathrm{h}\dot{\mat ..."
