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, Calif. (KGTV) - A fraternity at San Diego State has been placed under interim suspension after a freshman membered was injured.The mother of the student told 10News he suffered a concussion, as well as a fractured wrist, sprained ankle, and bruises on his back.It’s unclear exactly when or how the injuries occurred, but the student’s mom said he had been at an event at the Kappa Alpha fraternity house on Wednesday, October 17. She claims he “blacked out” from drinking too much alcohol.He made it back to his dorm, not receiving any medical care until hours later when a nurse administering meningitis shots noticed his injuries.San Diego State issued a statement to 10News, writing: 710

SAN DIEGO (KGTV): A vacant lot next to the College-Rolando area library has become a dumping ground for homeless people and their trash. Now neighbors are fed up and want the owners to do something about it."My house is not even this trashy," says Erin Webster, who visits the library every day. "I keep my house clean. I think we should keep this whole community clean."The lot, at 6650 Montezuma Road, is owned by 52 Blue Falcon LLC, an investment group. They've filed paperwork with the city to build a 4-story Holiday Inn Express on the property. They're still waiting for final city approval."Everybody's trying to get through this process as quickly as possible," says Jeannette Temple with the Atlantis Group, who is a consultant on the project.In the meantime, homeless people have broken through the fence blocking off the lot. There are piles of mattresses, food, tents, electronics and other garbage piled up on every side.Temple told 10News the owners hired a cleaning company to come this week and remove the trash. She also says they have contracted with a security company to come twice a day and kick out anyone who doesn't belong.She says they welcome the complaints from the community and the owners want to know when things aren't right."We appreciate their eyes and ears because we don't want anything bad to happen at the property either," says Temple.Temple says the owners hope to start construction on the hotel at the start of 2019 and it should take about 18 months to finish.City of San Diego representatives say there are ways people can report problem properties in their neighborhood.

SAN DIEGO, Calif. (KGTV) Firefighters continue to mop up after the Valley Fire tore through Lawson Valley, burning 17,665 acres.Messages of gratitude for the crews on the frontlines can be seen throughout the area.At least 30 homes and 31 minor structures were destroyed, but all evacuation orders and road closures were lifted on Friday.In much of the burn area, firetrucks have been replaced with utility vehicles.“I watched the flames start coming over the mountain, like fingers, like some creature,” said Seth Matteson who lives in Lawson Valley.He left his home as the fire started to spread Sept. 5, fearing the worst, but was thankful to come home and find his house on Prairie Drive still standing.“In the back it came right up to the house, and in the front it came right up to the house,” he explained.Just down the road, several homes and vehicles burned in the fire.“I’ve been through 8 hurricanes, and this is way scarier to me than that. When I see flames coming at me at 20 to 30 miles an hour or however fast they were,” he said.The County of San Diego has set up an assistance center at Rancho San Diego Library to help residents affected by the Valley Fire.People in need of assistance can also click here or call 858-715-2200. 1254

SAN FRANCISCO (AP) — An appeals court has rejected a former Stanford University swimmer's bid for a new trial and upheld his sexual assault conviction.The three-judge panel of the 6th District Court of Appeal ruled unanimously Wednesday that Brock Turner received a fair trial.A San Jose jury in 2016 convicted Turner of sexually assaulting a young, intoxicated woman outside an on-campus fraternity party.Judge Aaron Persky rejected a prosecutor's demand for a lengthy prison term and instead sentenced him to six months in jail. Turner appealed the conviction, arguing he didn't receive a fair trial.Persky's sentence sparked nationwide outrage by those who felt it too lenient. It also led to debate over the criminal justice system's handling of sexual assault victims.Voters recalled Persky in June. 812
