Abstract: The thermal state is determined for a system of two-qubit Heisenberg anisotropic XYZ spin chain in an inhomogeneous constant magnetic field with the Dzyaloshinskii-Moriya interaction. Their energy eigenvalues and the corresaponding eigenstates are evaluated. The quantum standard teleportation protocol based on this thermal state is studied for various input states. The fidelity is discussed for input and output states of the quantum channel.

Abstract: Quantum-dot cellular automata (QCA) are nanoscale digital logic constructs that use electrons in arrays of quantum dots to carry out binary operations. A basic building block for QCA will be proposed. The proposed basic building block can be customized to implement Half Adder circuit with less cell count and/or better latency than other proposed designs.

Abstract: Quantum computers requires quantum processors. An important part of the processor of any computer is the arithmetic unit, which performs binary addition, subtraction, division and multiplication, however multiplication can be performed using repeated addition, while division can be performed using repeated subtraction. In this paper we presents two designs using the reversible R^3 gate to perform the quantum half adder/subtractor and the quantum full adder/subtractor. The proposed half adder/subtractor design can be used to perform different logical operations, such as AND, XOR, NAND, XNOR, NOT and copy of basis. We show that the proposed design is more efficient than comparable designs.
