Time crystals lead researchers to future computer work

Time crystals sound like something out of science fiction, but they could be the next big leap in quantum network research. A team based in Japan proposed a method to use time crystals to simulate massive networks with very little computing power. They published their results on October 16 Advances in science. Time crystals, which were theorized for the first …

Google Pixel 5: This is what the pioneers of computer photography will offer in 2020

Google’s Pixel 5 includes regular and ultra-wide angle cameras. Screenshot by Stephen Shankland / CNET Google’s Pixel 5 flagship smartphone drops the telephoto camera offered by its predecessor to capture distant subjects and instead switches to an ultra-wide-angle alternative that is suitable for photographing groups of people and indoor scenes. The shift follows Apple’s iPhone 11, which added an ultrawide …

Hartree-Fock on a superconducting qubit quantum computer

Twelve qubit quantum computers for chemistry Accurate electronic structure calculations are considered to be one of the most anticipated applications of the quantum computer that will revolutionize theoretical chemistry and other related fields. Using the Google Sycamore quantum processor, Google AI Quantum and coworkers performed a VQE (Variational Quantum Self Solver) simulation of two medium-scale chemical problems: the binding energy …

Quantum computer power could soon hit a wall due to interference from cosmic rays

An MIT study reports that incident cosmic rays can limit qubit performance and hinder progress in quantum computing. Photo credit: Christine Daniloff, MIT Researchers note that underground quantum computers may need to be built or radiation-safe qubits designed. The practicality of Quantum computing depends on the integrity of the quantum bit or qubit. Qubits, the logical elements of quantum computers, …

Computer scientists set standards to optimize the performance of quantum computers

Credit: CC0 Public Domain Two UCLA computer scientists have shown that existing compilers that tell quantum computers how to use their circuitry to run quantum programs affect the computers’ ability to achieve optimal performance. In particular, their research has shown that improving the quantum compilation design can help achieve computational speeds up to 45 times faster than currently shown. The …
