Xanadu Lands $100 Million as Investments Pour Into Quantum Computing

1621999659 social
Xanadu Quantum Technologies Inc., which aims to commercialize quantum computing using particles of light, has raised $100 million in new funding as investor interest in the industry heats up.On Tuesday, Xanadu announced a Series B funding led by Bessemer Venture Partners, one of Silicon Valley’s oldest such firms. Funding to date for the five-year-old company now totals $145 million, said Christian Weedbrook, founder and chief executive of Xanadu. Quantum computing has the potential to solve some problems many millions of times faster than a conventional computer, which is why major technology companies and startups are working to commercialize it using various approaches. Traditional computers store information as either zeros or ones. Quantum computers use quantum bits, or qubits, which represent and...

Google Aims for Commercial-Grade Quantum Computer by 2029

1621391137 social
Alphabet Inc.’s Google plans to spend several billion dollars to build a quantum computer by 2029 that can perform large-scale business and scientific calculations without errors, said Hartmut Neven, a distinguished scientist at Google who oversees the company’s Quantum AI program. The company recently opened an expanded California-based campus focused on the effort, he said.“We are at this inflection point,” said Dr. Neven, who has been researching quantum computing at Google since 2006. “We now have the important components in hand that make us confident. We know how to execute the road map.” Chief Executive Sundar Pichai announced the timeline and introduced the new Google Quantum AI campus in Santa Barbara County on Tuesday at Google’s annual developer...

Quantum Computing Scientists Call for Ethical Guidelines

1621524761 social
A group of quantum computing experts, including scientists and company executives, want to raise ethical concerns about the technology’s potential to create new materials for war and accelerate human DNA manipulation.Six experts are featured in a 13-minute video titled “Quantum Ethics: A Call to Action,” which goes live Monday on YouTube and the Quantum Daily, a free online source for quantum computing news. The goal of the video, which features a former quantum chief at Alphabet Inc.’s Google, is to kick off conversations with other quantum computing industry leaders about the ethical implications of the technology. “Whenever we have a new computing power, there is potential for benefit of humanity, [but] you can imagine ways that it would also hurt people,” said John Martinis, professor of...

Quantum computing is so last-decade. Get ready to invest in the final frontier… teleportation

social
If 2020 had you wishing you could say “Beam me up, Scotty,” you’re not alone. You may be one tiny step closer to getting your wish… in a few decades or so. Scientists from Fermilab, Caltech, NASA’s Jet Propulsion Laboratory and the University of Calgary achieved “long-distance quantum teleportation” in mid-2020, they confirmed in an academic journal article published last month. It’s another step toward realizing what’s often called quantum computing, and also toward understanding physics on a different level than we do now, perhaps well enough to someday teleport humans. And while there is no ETF specifically for that yet, here are some broad guidelines for thinking about how to invest in very nascent technologies. For starters, it’s good to understand the broad contours of the industry supporting the idea. A...

Opinion: Quantum computers’ power will remake competition in industries from technology to finance

1620327491 social
Quantum computers, once fully scaled, could lead to breakthroughs on many fronts — medicine, finance, architecture, logistics. First, it’s important to understand why quantum computers are superior to the conventional ones we’ve been using for years: In conventional electronic devices, memory consists of bits with only one value, either 0 or 1. In quantum computing, a quantum bit (qubit) exhibits both values in varying degrees at the same time. This is called quantum superposition. These ubiquitous states of each qubit are then used in complex calculations, which read like regular bits: 0 and 1. Since qubits can store more information than regular bits, this also means quantum computers are capable of processing greater quantities of information. Having four bits enables 16 possibilities, but only one at a time. Four qubits in...
