Absence of Barren Plateaus in Quantum Convolutional Neural Networks


Abstract:  Quantum neural networks (QNNs) have generated excitement around the possibility of efficiently analyzing quantum data. But this excitement has been tempered by the existence of exponentially vanishing gradients, known as barren plateau landscapes, for many QNN architectures. Recently, quantum convolutional neural networks (QCNNs) have been proposed, involving a sequence of convol... » read more

Quantum Random Numbers Future-Proof Encryption


It may be a decade or more before quantum computers become common enough that we'll find out whether "post-quantum cryptography" will stand up to genuine quantum computers. In the meantime, some quantum researchers are peeling off specific functions and turning them into products or companies so that it's possible to take advantage of the potential of quantum computers without actually havin... » read more

Nanodevices for extreme environments in space, on earth Researchers at the Stanford Extreme Environment Microsystems Laboratory (XLab) are on a mission to conquer conditions such as those found on Venus: a hot surface pelted with sulfuric acid rains, 480 degrees C, an atmosphere that would fry today’s electronics. By developing heat-, corrosion- and radiation-resistant electronics, the team ... » read more

Manufacturing Bits: March 7


Materials database Electronic materials and nanocrystals are used in a variety of applications. To integrate materials and crystals in devices, researchers must search in multiple places to discover new technologies and their various properties. On top of that, researchers may require long hours in the lab, and large computational resources, to enable new materials. Seeking to help res... » read more

Missing magnetism of plutonium found In a discovery by two national labs that could hold great promise for materials, energy and computing applications, plutonium’s magnetism has been confirmed, which scientists have long theorized but have never been able to experimentally observe. According to Oak Ridge National Lab and Los Alamos National Lab, plutonium was first produced in 1940. Its ... » read more
