Fast, unconditional reset and leakage reduction in fixed-frequency transmon qubits

Abstract On-demand qubit-state initialization is a prerequisite for quantum computation. We demonstrate such a protocol in a device consisting of fixed-frequency transmon qubits pair-wise coupled via tunable couplers — an architecture that is also compatible with the surface code...

Mechanical Properties of Natural Fibre-Reinforced Polymer Composites with Carbon Nanofillers: Experimental and Mesoscale Modelling

Abstract Incorporating carbon nanotubes (CNTs) or graphene nanoplatelets (GNPs) into thermoplastic composites enhances electrical and thermal conductivity, as well as fire resistance, but may impair mechanical performance. To address this challenge and develop multifunctional yet...

Deep learning-based surrogate model for generation of wood microstructures

A machine learning-based surrogate model for efficient wood microstructure generation compatible with a physics-based model is developed. The model is based on the U-Net neural network, a variant of convolutional neural network which, due to its architecture, is suitable for imag...
