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 DIEGO (KGTV) - San Diego Police say a man was stabbed by his ex-girlfriend in a home on 3500 block of Adams Avenue just before 2:45 p.m. Sunday.A witness said she saw the man hobbling after the ex-girlfriend as she drove off.

Police say he is in stable condition.The ex-girlfriend returned to the scene and was arrested. Police say another man was arrested, who was involved with the ex-girlfriend.Adams Avenue westbound at 36th Street is shut down, and may reopen around 6 p.m., according to police. 728

San Diego (KGTV)- As Westin Hotel workers fight for better wages, local business owners are fighting to keep business.Hotel workers have been on strike for the past few weeks. Business owners say customers are now avoiding the area and its costing them money.Joey Aiello owns a shoe shine stand that sits outside of The Westin Hotel. He says he’s seen fewer customers this month because of the strike. “People don’t think its a big business but it supports my family,” says Aiello.He says since the workers hit the picket line, he’s lost 00 in business. “The first week they were here I made less than 0 a day. We have to make 0 a day to stay a float.” Other business also say they are concerned about the noise.The San Diego Police Department says they have received six complaints since October 9th. A spokesperson with Marriott International sent us this statement that says in part:“We are disappointed with some of the tactics the union has deployed including the noise levels. We continue to work with local police to address these issues and we are grateful to our guests for their patience during this time.”The Unite Here Union President, Bridgette Browning, says employees are now in negotiations with the hotel. She also sent us a statement that says:“While we are sympathetic to neighboring businesses - we believe the Marriott has the power to fix this strike and the businesses should be demanding that Marriott do the right thing. The workers are not to blame for the low standards that Marriott has created at the Westin San Diego Gaslamp. The workers are prepared to settle as soon as Marriott decides to do the right thing and sign a contract that provides living wages.”For business owner Joey Aiello, he says he won’t be able to make back the money he’s lost. “I just have to work harder and keep everything a float the best I can.” 1869

SAN FRANCISCO (AP) — After successive years of devastating wildfires, California's fire agency announced a plan Tuesday that would dramatically increase logging and other forest management efforts with the help of the National Guard.The California Department of Forestry and Fire Protection released a list of 35 priority fuel-reduction projects it wants to start immediately across the state over roughly 90,000 acres. That's double the acreage the agency aimed to cover in the current fiscal year, CalFire Deputy Chief Scott McLean said.The agency is also seeking National Guard assistance to coordinate the work. McLean said it was the first time he could recall turning to the National Guard for help with clearing trees and vegetation.RELATED: San Diego County areas on Cal Fire list of high-priority fire projects"It just goes to show you how committed everybody is," he said.The deadliest U.S. fire in a century destroyed much of Paradise — a city of 27,000 people in Northern California — in November 2018 and killed 86 people. California also experienced devastating wildfires in 2017, including a blaze that killed 22 people and destroyed more than 5,500 structures around the wine country city of Santa Rosa.Republican President Donald Trump has repeatedly criticized California's Democratic officials for not doing a good enough job managing its forests and has threatened to cut off California's federal disaster funding.RELATED: Southern California wildfire burn zones on alert during stormThe 35 projects are based on input from local Calfire units and would reduce wildfire risk to more than 200 communities, according to Calfire. They include removing dead trees, clearing vegetation, and creating fuel breaks, defensible spaces and ingress and egress corridors.The projects prioritize communities at high risk from wildfires but also with significant numbers of vulnerable groups such as the elderly or poor. They include work around the city of Redding, which was also devastated by wildfire last year, and in Butte County, where Paradise is located.An estimated 15 million acres of forest land in California are in need of thinning or other restoration work, so the 35 projects are just a start, Calfire officials said. The agency wants to establish incident bases with the National Guard close to vulnerable communities to coordinate fuel-reduction projects.RELATED: PG&E: Company's equipment may have ignited Camp FireKathryn Phillips, director of Sierra Club California, said many of the recent fires were driven by high winds, so clearing trees and vegetation is not the solution. Calfire should focus more on clearing brush around homes and ensuring their roofs and attics are safe from flying embers, she said."We need to make sure we're doing the things that we know will protect homes," she said.Calfire does call on officials to identify options for retrofitting homes as part of its recommendations released Tuesday. 2954

SAN FRANCISCO (AP) — A federal judge in San Francisco is mulling the competency to stand trial of a Mexican man who shot and killed 32-year-old Kate Steinle. The 2015 shooting figured prominently in President Donald Trump’s run for the White House four years ago. The case against Jose Ines Garcia Zarate on federal gun charges has been pending since a judge raised “serious concerns” about Garcia Zarate's mental capacities back in January. Two doctors have diagnosed Garcia Zarate with schizophrenia and found him unfit to stand trial. The San Francisco Examiner reports that Garcia Zarate told the court Friday through a Spanish interpreter that he wanted to be sentenced to prison or deported back to Mexico. 720
