New Qubits Could Make Quantum Computers More Compact
Villigen – Researchers from the Paul Scherrer Institute based in Villigen in the canton of Aargau are focused on the creation of topological quantum bits. These quantum bits, or qubits for short, form the basis of future quantum computers. More stable and therefore superior topological qubits would make quantum computers particularly efficient and compact. Niels …
2021 Year In Review: Google Quantum AI
Google’s Quantum AI team has had a productive 2021. Despite ongoing global challenges, we’ve made significant progress in our effort to build a fully error-corrected quantum computer, working towards our next hardware milestone of building an error-corrected quantum bit (qubit) prototype. At the same time, we have continued our commitment to realizing the potential of …
Stanford Physicists Help Create Time Crystals With Quantum Computers
There is a huge global effort to engineer a computer capable of harnessing the power of quantum physics to carry out computations of unprecedented complexity. While formidable technological obstacles still stand in the way of creating such a quantum computer, today’s early prototypes are still capable of remarkable feats. For example, the creation …
Futurism Is A Means To See Beyond COVID-19. Here’s How To Time Travel
This article is part of the Global Technology Governance Summit The COVID-19 crisis is shining a Klieg light on the immense challenges of planning for the future amid extreme uncertainty. Now more than ever, leaders need tools to help them understand where they are headed beyond the near-term. Futures discussions can feel like a blizzard of …
Lack Of Symmetry In Qubits Can’t Fix Errors In Quantum Computing, But Might Explain Matter/Antimatter Imbalance
A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of …
IBM Tops U.S. Patent List For 28th Consecutive Year With Innovations In Artificial Intelligence, Hybrid Cloud, Quantum Computing And Cyber-Security
IBM scientists and researchers received 9,130 U.S. patents in 2020, the most of any company, marking 28 consecutive years of IBM patent leadership. IBM led the industry in the number of artificial intelligence (AI), cloud, quantum computing and security-related patents granted. “The world needs scientific thinking and action more than ever. IBM’s sustained commitment to …
New Algorithm Could Unleash The Power Of Quantum Computers
A new algorithm that fast forwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations. “Quantum computers have a limited time to perform calculations before their useful quantum nature, which we call coherence, breaks down,” said …
Simulating Quantum ‘Time Travel’ Disproves Butterfly Effect In Quantum Realm
Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no “butterfly effect.” In the research, information—qubits, or quantum bits—“time travel” into the simulated past. One of them is then strongly damaged, like stepping on a butterfly, metaphorically speaking. Surprisingly, when all qubits return to the “present,” …
UC Berkeley To Lead $25 Million Quantum Computing Center
As part of the federal government’s effort to speed the development of quantum computers, the National Science Foundation (NSF) has awarded the University of California, Berkeley, $25 million over five years to establish a multi-university institute focused on advancing quantum science and engineering and training a future workforce to build and use quantum computers. The …
Machine Learning Pushes Quantum Computing Forward
Researchers have created a machine learning framework to precisely locate atom-sized quantum bits in silicon. It’s a crucial step for building a large-scale silicon quantum computer, the researchers report. Here, Muhammad Usman and Lloyd Hollenberg of the University of Melbourne explain their research and what it means for the future of quantum computers: Quantum computers are expected to offer …
