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 -- A massive fire broke out at a two-story commercial building in San Francisco Saturday night, according to KRON.The fire started inside the building and spread outward. The blaze took roughly 140 firefighters to extinguish.A total of eight people were displaced by the fire, but no one was injured.The cause of the fire is under investigation. 367

San Diego (KGTV)- For many people who live on a fixed income buying groceries may be a challenge. But now, 95,000 San Diegans receiving Supplemental Security Income, or SSI, will be able to apply for the CalFresh program (food stamps). “Individuals receiving SSI receives no more than 0 a month,” says Amanda Schultz Brocheo, with the San Diego Hunger Coalition. “For the majority, of SSI recipients, this all the money they have.”In San Diego, 1 in 11 older adults don’t have enough food to eat. “In some cases, we’ve heard of SSI recipients that will pull out a calendar and circle the days they are going to choose not to eat.”The San Diego Hunger Coalition says they are happy about the expansion but say the amount per day the is less than a day. “We determined that here in San Diego County the average CalFresh allotment is .07 a day.” This week also marks CalFresh Challenge Week. The organization encourages San Diegans to try living off a day for food. It’s meant to bring awareness to the food insecurities around the county. “We know that the CalFresh program is our strongest tool to for fighting hunger and also recognize that the current allotment is fairly small,” says Brocheo. “It makes it fairly difficult for people to live on that amount. With that said that a day is a more than they would have received otherwise.”To apply for the CalFresh program: - apply online- Call 2-1-1 - attend an upcoming CalFresh program event 1466

SAN DIEGO (KGTV)-- President Donald Trump announced in a tweet that he is rolling back on federal fair housing requirements, saying suburbanites will no longer be "bothered" by low-income housing. But some experts say this may not have a significant effect in San Diego County.It all began with the 1968 Fair Housing Act (FHA), a law that came out of the Civil Rights Era, abolishing lending discrimination and redlining neighborhoods according to race and other factors."A lot of communities here in San Diego, you can look at your deeds, and if you look in a pre-war neighborhood here, you are very likely to see that in the past, there was covenant against selling to a person of color," Stephen Russell, Executive Director of the San Diego Housing Federation, said. "That history is not that old."Then came the Obama-Era Affirmatively Furthering Fair Housing (AFFH Rule). This was a supplement to the FHA that required local governments receiving federal funds to create plans to fight continued housing discrimination.But on Wednesday, President Trump tweeted:"I am happy to inform all of the people living their Suburban Lifestyle Dream that you will no longer be bothered or financially hurt by having low income housing built in your neighborhood ... Your housing prices will go up based on the market, and crime will go down. I have rescinded the Obama-Biden AFFH Rule. Enjoy!"While this may seem like a blow to local affordable housing advocates, Russell believes this tweet is more of a political stunt to appeal to Suburbanites outside of California."Housing policies are largely enacted at the local level. At the state and local level," Russell said. "The state has reaffirmed its commitment to fair housing time and again."Encinitas has been a local municipality with a history of resisting affordable housing. But in the last few years, Russell says it has started to turn the corner.With or without this change in the federal mandate, he says municipalities here, still must continue to follow local rules."Regardless of what the man tweets, it's not going to change the way the State of California does business," says Russell. 2153

SAN DIEGO (KGTV) – A California Assemblymember Thursday requested a state audit to review how that City and County of San Diego responded to a recent hepatitis A outbreak.In a letter to the Joint Legislative Audit Committee, Assemblymember Todd Gloria asks that the committee “determine whether both the County and City identified, contained, and treated the recent Hepatitis A virus (HAV) outbreak in accordance with statutory requirements and recommended procedures.”“We owe it to the 20 people who died and the more than 500 who contracted Hepatitis A to learn exactly what went wrong and what could have been done better,” said Assemblymember Todd Gloria. “It is my hope this audit will help us better understand how the City and County managed the Hepatitis A outbreak and ultimately make certain our region is sufficiently prepared to handle any future public health crisis that may arise.”According to the letter, the hepatitis A outbreak started in March of 2017. In September of 2017, county health officials declared a public health emergency.The county ended the public health emergency declaration in January of 2018.Assemblymember Gloria’s request for an audit will be heard by the committee on May 16.A spokesperson for San Diego Mayor Kevin Faulconer responded with the following statement on the request for an audit: 1346
