Quantum transport in Cooper pair splitters using hierarchical equations of motion
Riya Baruah, Neill Lambert, Franco Nori +1
We investigate charge transport in Cooper pair splitters beyond the weak-coupling and Markovian limits. To this end, we employ hierarchical equations of motion (HEOM), which can ca…
Photon-energy-programmable subnanometric electron birth-site control
Hirofumi Yanagisawa, Abhisek Sinha, Ravi Kumar +2
Optical control of electron-generation sites has broadly enabled ultrafast nanoscale imaging, spectroscopy, and functional control. Existing approaches achieve nanoscale site selec…
Strongly-coupled non-Markovian waveguide QED with input-output HEOM
Neill Lambert, Yi-Te Huang, Yueh-Nan Chen +2
We consider the problem of modeling a single qubit in contact with a one-dimensional waveguide beyond the standard perturbative and Markovian approximations. Using the recently dev…
Experimental simulation of postselected closed timelike curves for decoding scrambled quantum information
Yi-Te Huang, Hsiang-Wei Huang, Jhen-Dong Lin +5
Quantum information scrambling (QIS) describes the rapid spread of initially localized information across an entire quantum many-body system through entanglement generation. Once s…
Resource efficient certification of system environment entanglement solely from reduced system dynamics
Jhen-Dong Lin, Pao-Wen Tu, Kuan-Yi Lee +4
Certifying nonclassical correlations typically requires access to all subsystems, presenting a major challenge in open quantum systems coupled to inaccessible environments. Recent…
HierarchicalEOM.jl: An efficient Julia framework for hierarchical equations of motion in open quantum systems
Yi-Te Huang, Po-Chen Kuo, Neill Lambert +5
The hierarchical equations of motion (HEOM) approach can describe the reduced dynamics of a system simultaneously coupled to multiple bosonic and fermionic environments. The comple…
