Multivalued logic gates for quantum computation
We develop a multivalued logic for quantum computing for use in multi-level 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 d-level systems (d .2) can be decomposed into logic gates that operate on only two systems at a time....
متن کاملReversible logic synthesis by quantum rotation gates
A rotation-based synthesis framework for reversible logic is proposed. We develop a canonical representation based on binary decision diagrams and introduce operators to manipulate the developed representation model. Furthermore, a recursive functional bi-decomposition approach is proposed to automatically synthesize a given function. While Boolean reversible logic is particularly addressed, ou...

Lond., (to be published). 37] The only non-trivial one-bit classical invertible operation is 0 1 1 0. 41] Corresponding with the deenition in the previous section, the top two wires contain the input bits x 1 and x 2 , and the third wire contains the input y). 42] The angle-halving of this deenition conforms to ...
متن کاملElementary gates for quantum computation.
We show that a set of gates that consists of all one-bit quantum gates (U(2)) and the two-bit exclusive-or gate (that maps Boolean values (x, y) to (x, x⊕y)) is universal in the sense that all unitary operations on arbitrarily many bits n (U(2n)) can be expressed as compositions of these gates. We investigate the number of the above gates required to implement other gates, such as generalized D...
متن کاملSynthesis of Ternary Quantum Logic Circuits by Decomposition
Recent research in multi-valued logic for quantum computing has shown practical advantages for scaling up a quantum computer. [1,12] Multivalued quantum systems have also been used in the framework of quantum cryptography, [4] and the concept of a qudit cluster state has been proposed by generalizing the qubit cluster state. [5] An evolutionary algorithm based synthesizer for ternary quantum ci...
