Abstract Quantum computers offer significant potential for complex system analysis, yet their application in large systems is hindered by limitations such as qubit availability and quantum hardware noise. While the variational eigensolver (VQE) was proposed to address these issues, its scalability remains limited. Many efforts, including new ansätze Hamiltonian modifications, have been made overcome challenges. In this work, we introduced novel Fragment Molecular Orbital/Variational...
Abstract Quantum computing devices are inevitably subject to errors. To leverage quantum technologies for computational benefits in practical applications, algorithms and protocols must be implemented reliably under noise imperfections. Since imperfections limit the size of circuits that can realized on a device, developing error mitigation techniques do not require extra qubits gates is critical importance. In this work, we present deep learning-based protocol reducing readout errors...
Abstract 2D transition metal dichalcogenides (TMDCs) are anticipated to be the ones of future nano‐sized photodevices due their electronic and optoelectronic properties. They have shown remarkable performances as photodetectors from being fabricated into heterostructures with p–n junction. An oxygen plasma‐doped WSe 2 /pristine MoS ‐based photodetector high responsivity broad detection spectrum ranging visible near‐infrared (NIR) region is reported. The plasma treatment forms a WO x layer on...
An extreme ultraviolet (EUV) pellicle consists of freestanding thin films on a frame; these are tens nanometers in thickness and can include Si, SiNX, or graphite. Nanometer-thick graphite (NGFs), synthesized via chemical vapor deposition metal catalyst, used as material. The most common method to transfer NGFs onto substrate frame is use polymethyl methacrylate (PMMA) supporting layer. However, this PMMA-mediated technique involves several disadvantages term manufacturing NGF EUV pellicles....

Carrier–carrier interactions or disorders strongly affect the quantum localization–delocalization of carriers which leads to metal insulator transition (MIT) in two-dimensional (2D) systems. However, physical origin MIT 2D systems remains controversial. Here, we report black phosphorus (BP) nanosheet-based devices with and without encapsulation hexagonal boron nitride (hBN). In hBN encapsulated BP devices, perform critical scaling analysis elucidate microscopic by considering significant...
Abstract Despite the potential of quantum computers in analyzing complex systems, their applications for larger systems are hindered by limited qubit availability. Addressing this, our study presents novel FMO/VQE algorithm that combines fragment molecular orbitals and variational eigensolver methods, strategically designed optimal utilization fragment-based chemistry simulations.
