Optimal Realizations of Controlled Unitary Gates [PDF]
Journal of Quantum Information and Computation, 3(2), pages
139-155, 2003, 2002 The controlled-not gate and the single qubit gates are considered elementary gates in quantum computing. It is natural to ask how many such elementary gates are needed to implement more elaborate gates or circuits. Recall that a controlled-U gate can be realized with two controlled-not gates and four single qubit gates.

Responsive Molecules for Organic Neuromorphic Devices: Harnessing Memory Diversification
Advanced Materials, EarlyView.Responsive molecules are essential for organic in‐sensor computing devices. This Review highlights recent advances in thedesign, synthesis, and incorporation of electrically, optically, and magnetically responsive molecules in multifunctional synaptic perception devices endowedwith both nonvolatile and volatile memory diversification. By exploiting the

The simplified Toffoli gate implementation by Margolus is optimal [PDF]
arXiv, 2003 Unitary operations are expressed in the quantum circuit model as a finite sequence of elementary gates, such as controlled-not gates and single qubit gates. We prove that the simplified Toffoli gate by Margolus, which coincides with the Toffoli gate up to a single change of sign, cannot be realized with less than three controlled-not gates.

Advanced Materials, EarlyView.This study investigates bias‐induced structural transformations in 1T‐TiSe2 devices, focusing on the transition from the 1T metallic phase to the distorted 1Td phase and ultimately to an orthorhombic Ti9Se2 conducting phase. Using ex‐situ and in‐situ TEM, dynamic structural changes and insights into the effect of thickness on phase transitions ...

Optimal simulation of three-qubit gates [PDF]
arXiv, 2013 In this paper, we study the optimal simulation of three-qubit unitary by using two-qubit gates. First, we give a lower bound on the two-qubit gates cost of simulating a multi-qubit gate. Secondly, we completely characterize the two-qubit gate cost of simulating a three-qubit controlled controlled gate by generalizing our result on the cost of Toffoli ...
