Performance of Krotov, PRONTO and PINN for optimal control of quantum gates

Martín D. Jiménez, Murilo D. Forlevesi, Emanuel F. de Lima +1

Achieving scalable quantum computing demands high-fidelity operations capable of mitigating population leakage into non-computational states. Physics-Informed Neural Networks (PINN…

Reverse engineering of single-qubit quantum gates

Gustavo Fernandes da Costa, Leonardo K. Castelano, Emanuel Fernandes de Lima

In this work, we address the problem of designing single-qubit quantum gates by means of a linearly-polarized field. We show that any desired one-qubit gate corresponding to a spec…

Phase-Topology Classification of Memristor Hysteresis Loops via Self-Crossings

Ovidiu-Zeno Lipan, Eric Neuhaus, Rafael Schio Wengenroth Silva +6

Memristive devices have revolutionized non-volatile memory and neuromorphic computing, yet the geometry of their hysteresis loops -- in particular, the occurrence and robustness of…

2D Canonical Approach for Beating the Boltzmann Tyranny Using Memory

Rafael Schio Wengenroth Silva, Soumen Pradhan, Fabian Hartmann +4

The 60 mVdecade subthreshold limit at room temperature, coined as the Boltzmann tyranny, remains a fundamental obstacle to the continued down-scaling of conventional transistors…

Minimal-Energy Optimal Control of Tunable Two-Qubit Gates in Superconducting Platforms Using Continuous Dynamical Decoupling

Adonai Hilário da Silva, Octávio da Motta, Leonardo Kleber Castelano +1

We present a unified scheme for generating high-fidelity entangling gates in superconducting platforms by continuous dynamical decoupling (CDD) combined with variational minimal-en…

Gate-controlled analog memcapacitance in LaAlO3/SrTiO3 interface-based devices

Soumen Pradhan, Victor Lopez-Richard, Igor Ricardo Filgueira e Silva +8

Current memcapacitor implementations typically demand complex fabrication processes or depend on organic materials exhibiting poor environmental stability and reproducibility. Here…
