Researchers Take a Step Toward Building a Fault-Tolerant Quantum Computer

To build a universal quantum computer from fragile quantum components, effective implementation of quantum error correction (QEC) is an essential requirement and a central challenge. QEC is used in quantum computing, which has the potential to solve scientific problems beyond the scope of supercomputers, to protect quantum information from errors due to various noise.

New Technology Could Boost Quantum Computing and Superconducting Electronics

Superconductors -- materials that conduct electricity without resistance -- are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They're found in medical imaging, quantum computers, and cameras used with telescopes.

Breakthrough in Photonic Circuits Heralds a New Future for Quantum Computing, Communication

The modern world is powered by electrical circuitry on a "chip"--the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 zettabytes (175trillion gigabytes) of new data. How can we ensure the security of sensitive data at such a high volume- And how can we address grand-challenge-like problems, from privacy and security to climate change, leveraging this data, especially given the limited capability of current computers-
