SAN FRANCISCO — Firefighters say they hope dying winds will allow them to bear down on a wildfire that's exploded in the Northern California wine country.The Glass Fire, which was sparked on Sunday, tripled in size Monday and the San Jose Mercury News says some two dozen homes have burned.On Monday night, Cal Fire reported that the blaze was still 0% contained.About 70,000 people are under evacuation orders, including the entire town of Calistoga.Reports indicate that several iconic resorts in Napa County have been damaged or destroyed by the wildfire. 566

SAN FRANCISCO (AP) — Google announced Wednesday it has achieved a breakthrough in quantum computing, saying it has developed an experimental processor that took just minutes to complete a calculation that would take the world's best supercomputer thousands of years.The feat could open the door someday to machines so blazingly fast that they could revolutionize such tasks as finding new medicines, developing vastly smarter artificial intelligence systems and, most ominously, cracking the encryption that protects some of the world's most closely guarded secrets.Such practical uses are still probably decades away, scientists said. But the latest findings, published in the scientific journal Nature, show that "quantum speedup is achievable in a real-world system and is not precluded by any hidden physical laws," the researchers wrote.RELATED: Google Maps will now allow drivers to report hazards, slowdowns and speed trapsBig tech companies including Microsoft, IBM and Intel are avidly pursuing quantum computing, a new and somewhat bewildering technology for vastly sped-up information processing.While conventional computing relies on bits, or pieces of data that bear either a one or zero, quantum computing employs quantum bits, or qubits, that contain values of one and zero simultaneously.But quantum computing requires placing the fragile and volatile qubits in colder-than-outer-space-refrigerators to control them.Google's quantum processor looks like an upside-down garbage can, out of which comes a series of tubes used to conduct signals to a chip. The whole thing is stored in a cool chamber to protect the chip.RELATED: Google unveils new Pixel 4 smartphone, Pixel BudsGoogle said that its quantum processor, called Sycamore, finished a calculation in 3 minutes, 20 seconds — and that it would take the world's fastest supercomputer 10,000 years to do the same thing.The calculation was a random sampling problem, similar to looking at the various combinations that could come from dice or a gambling machine. It has little practical value, other than to test how well the processor works."The more interesting milestone will be a useful application," said Chris Monroe, a University of Maryland physicist who is also the founder of quantum startup IonQ.Google's findings, however, faced pushback from other industry researchers. A version of Google's paper leaked online last month.IBM took issue with Google's claim that it had achieved "quantum supremacy," or the point when a quantum computer can perform a calculation that a traditional computer can't complete within its lifetime.IBM researchers said that its IBM-developed supercomputer, called Summit, could actually do the calculation in 2.5 days.Google disputed IBM's claims.Whether or not Google achieved "quantum supremacy," the research suggests the field is maturing."The quantum supremacy milestone allegedly achieved by Google is a pivotal step in the quest for practical quantum computers," John Preskill, the Caltech professor who coined the term "quantum supremacy," wrote in a column after the paper was leaked.It means quantum computing research can enter a new stage, he wrote, though a significant effect on society "may still be decades away."One feared outcome — though experts said it is a long way off — is a computer powerful enough to break today's best cryptography.Quantum computers might also one day lead to the development of better artificial intelligence systems to guide financial portfolios, crop yields or transportation routes.The promise of such applications has attracted interest from the U.S., China and other governments. President Donald Trump last year signed a measure to spend more than .2 billion over five years for quantum research across the federal government. 3797

SAN FRANCISCO (AP) — Major changes to the way people vote has election advocates on edge as Californians cast ballots in the Democratic presidential contest and other primary races. The “Super Tuesday” primary in the country's most populous state comes amid changes aimed at expanding voter participation, including new voting equipment and vote centers that are replacing polling places in some counties. Those changes may confuse some people. There are fears California might end up with a mess much worse than Iowa, where the Democratic Party couldn't declare a winner for several days. Advocates say voters are hanging onto their ballots, which will likely mean long lines Tuesday. 694

San Diego (KGTV)- It’s been one year since the deadly bluff collapse in Encinitas, killing three members of the same family. The husband and father of two of the women is still calling for changes along the beach.Dr. Pat Davis says this past year has been tough after losing wife Julie Davis, daughter Annie Clave and sister-in-law Elizabeth Charles.The family was out for a day at the beach last August when suddenly the bluff gave out.“It was important for me that this kind of accident never is able to happen to any other family,” says Davis.Davis says since the tragic accident, there has been little change at Grandview beach. “There’s very few new signs warning people about these cliffs.”Davis is calling on local and state leaders to stabilize the bluffs. He’s hoping a new bill will help. S.B. 1090 offers solutions like sand replenishment. It currently sits in the Senate.“We got over 4,000 signatures in one month of people supporting the bill.”In the meantime, Davis is thanking the community for its continued support. A park bench sits at the top of Grandview Beach, honoring his family members.“Not that there’s an easy side of learning to live with the loss and one of your children but, certainly family support and community support has been a great help in allowing my family to move forward.”Davis says community members also came together to place another memorial bench in their neighborhood. 1423

SAN FRANCISCO (AP) — Amazon has eclipsed Microsoft as the most valuable publicly traded company in the U.S. as a see-sawing stock market continues to reshuffle corporate America's pecking order.The shift occurred Monday after Amazon's shares rose 3 percent to close at ,629.51 and lifted the e-commerce leader's market value to 7 billion. Meanwhile, Microsoft's stock edged up by less than 1 percent to finish at 2.06, leaving the computer software maker's value at 4 billion.It marks the first time Amazon has held the top spot and ends Microsoft's brief return to the pinnacle after it surpassed Apple in late November .The repositioning has been triggered by mounting concerns that the Trump administration's trade war with China and rising interest rates will bog down the worldwide economy. If that were to happen, it's likely to slow the growth of companies in technology and other industries that generate a substantial chunk of their revenue outside the U.S.That's one reason most technology stocks are well off their peaks. Amazon, for instance, remains 21 percent below its high reached in September when the company's stock value stood above trillion. Apple was worth even more back then, but its stock has plunged by 37 percent since early October to erase about 0 billion of its market value.Apple confirmed some of investors' worst fears last week when it warned that disappointing demand for iPhones, especially in China, caused its revenue for its most recent quarter to fall well below the projections of its management and industry analysts. 1584
