Quantum computing is promising to be one of the biggest technological revolutions of the modern era. By harnessing the power of quantum mechanics, machines will be able to achieve data processing of speed and complexity unattainable with current computers. Traditional computers are based on a binary model on a system of switches that can be either on or off, represented with a 1 or a 0. Quantum computers are different in that their switches can be in both the on and off positions at the same time, called ‘superpositions.’ This ability to be in two simultaneous states is what makes quantum computers faster. Much faster. Google announced over two years ago that the quantum prototype they possess was 100 million times faster than any other computer in their lab. To put it another way — in the 1990’s IBM built a supercomputer named Deep Blue that defeated world chess champion Garry Kasparov. Deep Blue had an edge over Kasporov because of its ability to calculate … [Read more...] about How quantum computing could wreak havoc on cryptocurrency

## Google’s Quantum Computing Party Is as Fancy as Physics Gets

“Want to come to a quantum computing party?” I wasn’t expecting the question. My brain was hurting: I’d just finished an hour-long interview with Jarrod McClean, a Google quantum computing scientist, and I was mentally planning to write up my notes. His talk had caught my attention the day before: McClean spoke animatedly, bobbing a magnificent head of shoulder-length ringlets, as he pointed at equations and diagrams on a PowerPoint presentation. His audience consisted of a room full of physicists at the American Physical Society March meeting, the largest physics conference in the world, and I was there to write for the organization’s newsletter. The first quantum computer algorithms, McClean told me, will simulate progressively more complicated molecules with the goal of eventually discovering new useful materials. Sure, I thought, I could do with some lighter chitchat. McClean dug around in his backpack and handed me a postcard with a spiky black … [Read more...] about Google’s Quantum Computing Party Is as Fancy as Physics Gets

## Google reclaims quantum computer crown with 72 qubit processor

Google yesterday unveiled the world’s largest quantum computer processor to date. Dubbed Bristlecone, it’s a 72-qubit gate-based superconducting system that blows the previous best, IBM’s 50-qubit processor, out of the water. The race to build the world’s first useful quantum computer is nearing its end. The Mountain View company’s Research at Google team created the 72-qubit processor by scaling its previous 9-qubit system. Its obvious goal is to provide the power and stability necessary for quantum computers to become functionally useful. Check out this story for a quick primer on what quantum computing is and this one if you want to learn some wild and wacky facts about it. According to a Google blog post: If a quantum processor can be operated with low enough error, it would be able to outperform a classical supercomputer on a well-defined computer science problem, an achievement known as quantum supremacy. Some experts believe this will happen at … [Read more...] about Google reclaims quantum computer crown with 72 qubit processor

## Google wants to push quantum computing mainstream with ‘Bristlecone’ chip

Google’s Quantum artificial intelligence lab recently revealed a new quantum processor that may pave the way for quantum computing to go mainstream. The new chip features 72 qubits according to Google and offers a compelling proof-of-concept for future, large-scale quantum computers. “Our strategy is to explore near-term applications using systems that are forward compatible to a large-scale universal error-corrected quantum computer,” Google’s announcement reads. All right, quantum computing is complicated, bizarre, and tough to explain but Google’s new Bristlecone chip is important for a few reasons. First of which, it’s designed to address one of the key problems facing quantum computing today: Error correction. Because traditional chips, like the one in your phone or your computer, or any other electronic device, all use Boolean logic — simple yes or no, on or off operations — error correction is fairly easy to implement. All of … [Read more...] about Google wants to push quantum computing mainstream with ‘Bristlecone’ chip

## Ready for “quantum supremacy”? Google’s Bristlecone quantum computing chip could outdo ordinary machines

Google has a quantum computer chip, called Bristlecone, and the company thinks it'll outdo the classical computers using today's silicon processor designs.Quantum computers, which stand to revolutionize at least part of the computing industry if anybody can ever figure out how to get them working, are benefiting from heavy investments at Google, IBM, Microsoft, Intel, D-Wave and others. Google detailed some of its plans Monday in a blog post about Bristlecone.For one thing, Google research scientist Julian Kelly said, the Bristlecone quantum computing chip has 72 qubits, the weird memory cells that endow quantum computers with their ability to store an immensely wide range of combinations of ones and zeros. For another, it should be able to outdo Google's earlier 9-qubit device when it comes to the essential technology of quantum error correction, which is key to keeping hypersensitive qubits from getting perturbed."We are cautiously optimistic that quantum supremacy can be achieved … [Read more...] about Ready for “quantum supremacy”?
