Pulse based Variational Quantum Optimal Control for hybrid quantum computing [PDF]
Quantum, 2023 This work studies pulse based variational quantum algorithms (VQAs), which are designed to determine the ground state of a quantum mechanical system by combining classical and quantum hardware. In contrast to more standard gate based methods, pulse based

A SEQUENCE OF QUANTUM GATES [PDF]
International Journal of Geometric Methods in Modern Physics, 2012 We study a sequence of quantum gates in finite-dimensional Hilbert spaces given by the normalized eigenvectors of the unitary operators. The corresponding sequence of the Hamilton operators is also given. From the Hamilton operators we construct another hierarchy of quantum gates via the Cayley transform.

Quantum Logic Gates Based on DNAtronics, RNAtronics, and Proteintronics
Advanced Intelligent Systems, 2021 Quantum computers (QCs) adopt an n‐state quantum mechanical system to manipulate the superposition state. However, molecular transistors are not used to build up the quantum logic gate.

A unified quantum NOT gate [PDF]
Journal of Physics A: Mathematical and Theoretical, 2009 We study the feasibility of implementing a quantum NOT gate (approximate) when the quantum state lies between two latitudes on the Bloch's sphere and present an analytical formula for the optimized 1-to-$M$ quantum NOT gate. Our result generalizes previous results concerning quantum NOT gate for a quantum state distributed uniformly on the whole Bloch ...

Logical quantum processor based on reconfigurable atom arrays [PDF]
Nature, 2023 Suppressing errors is the central challenge for useful quantum computing1, requiring quantum error correction (QEC)2–6 for large-scale processing. However, the overhead in the realization of error-corrected ‘logical’ qubits, in which information is ...
