Quantum Computing


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 …

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 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 …

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 …

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,” …

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 …

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 …

Advances in quantum computing could help us simulate large complex molecules. These simulations could uncover new catalysts for carbon capture that are cheaper and more efficient than current models. We can currently simulate small molecules up to a few dozen qubits but need to scale this to the order of 1 million. Imagine being able …

Google claims to have demonstrated something called “quantum supremacy”, in a paper published in Nature. This would mark a significant milestone in the development of a new type of computer, known as a quantum computer, that could perform very difficult calculations much faster than anything possible on conventional “classical” computers. But a team from IBM …

A quantum computer may have solved a problem in minutes that would take the fastest conventional supercomputer more than 10,000 years. A draft of a paper by Google researchers laying out the achievement leaked in recent days, setting off an avalanche of news coverage and speculation. While the research has not yet been peer-reviewed – …
