Abstract Practical quantum computing will require error rates well below those achievable with physical qubits. Quantum correction 1,2 offers a path to algorithmically relevant by encoding logical qubits within many qubits, for which increasing the number of enhances protection against errors. However, introducing more also increases sources, so density errors must be sufficiently low performance improve code size. Here we report measurement qubit scaling across several sizes, and...
The emergence of rapidly expanding infectious diseases such as coronavirus (COVID-19) demands effective biosensors that can promptly detect and recognize the pathogens. Field-effect transistors based on semiconducting two-dimensional (2D) materials (2D-FETs) have been identified potential candidates for rapid label-free sensing applications. This is because any perturbation atomically thin 2D channels significantly impact their electronic transport properties. Here, we report use FET...
Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin one-dimensional Heisenberg model were conjectured as to belong Kardar-Parisi-Zhang (KPZ) universality class based on scaling infinite-temperature spin-spin correlation function. a chain 46 superconducting qubits, we studied probability distribution magnetization transferred across chain's center, [Formula: see text].

Engineered dissipative reservoirs have the potential to steer many-body quantum systems toward correlated steady states useful for simulation of high-temperature superconductivity or magnetism. Using up 49 superconducting qubits, we prepared low-energy transverse-field Ising model through coupling auxiliary qubits.

The off-state drain current OP-TFT is significantly increased due to while a smaller relative effect observed on in strong-accumulation regime. illumination effectively decreases threshold voltage device and increases apparent subthreshold swing, field-effect mobility charge carriers channel unchanged. full recovery...
Low-temperature Ag sintering provides a lead-free die attachment method that is compatible with high-temperature (300 °C) power electronics applications. The reliability of sintered attach for Si and SiC has been studied on both thick film substrates lower current applications direct bond copper (DBC) higher Pressureless low-pressure were evaluated. Sintering low pressure yielded porosity (15-17%) versus pressureless (~30%). Reliability was evaluated thermal aging cycling (-55 °C to + 300...
Systems of correlated particles appear in many fields modern science and represent some the most intractable computational problems nature.
