Mitigating noise in digital and digital-analog quantum computation

Marcelo Castellanos2025-04-28T11:13:36+02:00Tags: Multidisciplinary. , Physics|

Authors: Garcia-Molina, Paula; Martin, Ana; de Andoin, Mikel Garcia; Sanz, Mikel Journal: COMMUNICATIONS PHYSICS Publication date: 2024/10/06 DOI: 10.1038/s42005-024-01812-5 Abstract: Noisy Intermediate-Scale Quantum (NISQ) devices lack error correction, limiting scalability for quantum algorithms. In this context, digital-analog quantum computing (DAQC) offers a more resilient alternative quantum computing paradigm that outperforms digital quantum computation by combining [...]

Different theoretical aspects of the intrinsic decoherence in the Milburn formalism

Authors: Mousavi, S. V.; Miret-Artes, S. Journal: EUROPEAN PHYSICAL JOURNAL PLUS Publication date: 2024/10/03 DOI: 10.1140/epjp/s13360-024-05654-6 Abstract: In this work, we consider different theoretical aspects and simple applications of the Milburn equation which is governed by a parameter controlling what is known as intrinsic decoherence. The main goal is to show some similarities also observed [...]

Authors: de Moraes, L. F. C.; Duriez, Alan C.; Saguia, A.; Santos, Alan C.; Sarandy, M. S. Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2024/10/01 DOI: 10.1088/2058-9565/ad71ed Abstract: We introduce a counter-diabatic (CD) approach for deriving Hamiltonians modeling superchargable quantum batteries (QBs). A necessary requirement for the supercharging process is the existence of multipartite interactions [...]
