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 - A hot air balloon with 14 passengers and a pilot on board made an unplanned landing in Rancho Pe?asquitos Sunday night.The balloon set down on a hillside at Pe?asquitos Drive and Del Diablo Way west of Interstate 15 about 7:15 p.m.The community jumped in to help, keeping the basket stable and helping the passengers exit safely, according to the San Diego Police Department.Witnesses helped the pilot bring the basket down to the street where it could be picked up by the owner, police said. The owner's name was not released.No one was injured.The NTSB will investigate the cause of the unplanned landing.  643

SAN DIEGO (KGTV)- Business owners across San Diego County were bracing for the possibility of shifting back into the most restrictive purple tier Tuesday.The county barely avoided the move and can stay in the red tier for now.“The up and down is very difficult to run any business without having any known information about what the future brings,” said Scott Lutwak, CEO of Fit Athletic Club, which has five locations in the county. “It’s been just a rollercoaster of open and close again.”If the county had to move back into the purple tier, gyms and fitness centers would have to go back to outdoor operations only.“It’s not easy to just move all the equipment that you had inside and move it into your parking lot and create a gym,” he said.Under the red tier, they can operate inside at 10 percent capacity. Lutwak said that’s still just not enough.“This number has been a very difficult number for our industry to digest because we simply cannot operate at 10 percent of our capacity.”Restaurants were also set to move back outside if we hit the purple tier. Under the red, they can offer indoor dining at 25 percent capacity.“There’s no clear path to 100 percent, there’s no plan to get us back open, and that’s really shocking to us,” said Angie Weber, co-owner of Cowboy Star Restaurant and Butcher Shop.She said her East Village business would not survive another shutdown.Weber said California’s color-coded tier system makes things more difficult for already struggling business owners, as they’re constantly worrying about what could happen next.“We need to fix this, we’re just going to be on this seesaw,” she said.While San Diego County teeters between the red and purple tiers with no orange or yellow in sight yet, both Lutwak and Weber hope county leaders and health officials can take back local control.“If we use the governor’s formula, our businesses are basically never going to be able to reopen,” said Lutwak. 1943

San Diego (KGTV)- Heart- pounding moments for visitors at the San Diego Zoo Safari Park. Powerful gusts tossed riders on the Balloon Safari from side to side. Riders on the balloon held on tight during the gusty landing. “There were some points where the basket was almost tipped completely sideways,” says Jordan Lapidot, who was visiting the park with her family yesterday afternoon. “I have this image in my mind of this guy, and he’s grabbing the outside of the cage as they get just thrown.”The San Diego Zoo Safari Park says the balloon has a long cable in the middle of the cage that safely brings it down from the sky. That cable never broke during the windy ride. “They were trying to get it down as quickly as possible,” says Lapidot. The Safari Park tells 10News if the wind reads over 29 miles per hour they will shut the ride down. They sent us a statement about the incident, saying in part: “As the sudden storm arrived and winds picked up, some operations at the Park, like Balloon Safari and Flightline were closed to public use.”No one was hurt while on the ride. 1090

SAN DIEGO COUNTY (KGTV)-- New SANDAG and San Diego County statistics show an alarming number of San Diegans of color are impacted by the coronavirus pandemic. Wednesday, community leaders and elected officials announced the creation of a new regional task force to tackle the root causes of the inequities.The coronavirus did not create society's inequities."But it has definitely exasperated them, and it has highlighted them," San Diego County Supervisor Nathan Fletcher said.That is why community leaders announced the creation of the new Regional COVID-19 Task Force for Equitable Recovery. They will work with elected officials to tackle the underlying problems that lead to inequities such as job, food, healthcare, and economic losses, felt by many San Diegans of color."You are valued," National City mayor, Alejandra Sotelo Solis, said in the Zoom announcement. "You have made a contribution to our community, and we want you to stay healthy.""The elected officials will then shoulder the obligation to take their recommendations and suggestions and translate them into policies that can be introduced for a vote to make the change real," Fletcher added.A newly released SANDAG report found that when compared to the white population, Black and Hispanic people are more than four times more likely to live in areas that have been impacted both by COVID-19 and unemployment.New San Diego County numbers show that while Hispanics and Latinos make up 34% of the county population, they account for 67% of the county's positive coronavirus cases."Not one community needs the testing, tracing, and treatment," JoAnn Fields with API initiative said. "But it needs to be on an equal level so that we are all protected as a whole community."The task force hopes to close the understanding, trust, access, and resource gap felt by people of color, in a proactive way. For example, even before a coronavirus vaccine comes out, they plan to have resource materials available in various languages and create policies that will distribute vaccines in heavily impacted zip codes."[We will try] to come up with messaging to the communities that we represent so that when the vaccine does become available, we will maybe get better compliance," Southeast San Diego physician, Dr. Rodney Hood, said.The public is welcome to join the task force's first Zoom meeting on June 24, 2020, at 4 PM. 2391
