SAN DIEGO — A YouTube video shows a community college police officer drawing his gun on a San Diego man carrying a camera Wednesday.The video shows the Mesa College police officer getting out of his car and asking Chris, the man with two cameras, what he was filming.Chris, who did not want to provide his last name, refused to put down the GoPro camera. Within seconds, the officer took his weapon out of the holster. The officer did not put his gun back in the holster until a second officer arrived.Chris is the founder of California Citizens Watch, a group that audits government entities. He told claims he was not trying to provoke the officer into pulling his gun.Watch the confrontation: Former El Cajon police officer Kevin LaChapelle believes Chris was definitely out for a confrontation. However, LaChapelle also said he believes the Mesa College officer should not have pulled his weapon.Mesa College released a statement which read: 993

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) -- Neighbors in Del Cerro say an intersection near their homes is a hot spot for accidents and speeding, with the latest incident occurring Monday night.The streets and intersection in question are Madra Avenue and Del Cerro Boulevard. Denisse Newell took cell phone video during the aftermath of Monday’s accident. Newell says she’s reached out to City of San Diego officials to ask that something be done to make drivers slow down.Another neighbor, Emily Broadwater, says she was involved in an accident at the intersection in 2018 after a man didn’t stop at the stop sign. Her minivan was totaled.Newell says her dog was also hit by a speeding car and survived the accident. Her husband has stopped walking their children to school after multiple close calls. Neighbors worry that the next time it’ll be a person. The women say they’d like the city to implement like speed bumps, a stoplight or roundabouts to get drivers to slow down.ABC 10News reached out to San Diego City Councilman Scott Sherman’s office, who represents the district. A spokesperson said they have heard from residents and are working with city staff to fix the problem. 1178

SAN DIEGO, Calif. (KGTV) - An alleyway in Hillcrest has transformed from dark and dirty to a work of art, and the revision isn’t complete yet.Patric Stillman is the owner of The Studio Door, an art gallery positioned in front of the alleyway. He said artists have been adding their work to the walls of the alleyway and it’s now grown into its own gallery that they’ve dubbed “mural alley.”“This was a pretty grungy space and over the past year we’ve been able to bring in some remarkable local muralists,” said Stillman.While artists continue to work on blank walls in the area, the Hillcrest Business Association is stepping in to take the space to the next level. Benjamin Nicholls, the Hillcrest Business Association Executive Director, said they’re asking the community for donations to fund-raise and add string lights that zig zag across the top of the alleyway.“Hillcrest mural alley is going to become a destination and it’s going to be a creative community destination,” said Nicholls.Nicholls added that in a coronavirus era when activities are safest outdoors, they hope this space will become an outdoor entertainment and event area.Even without the addition of the lights, it’s already catching eyes. Mother daughter duo Brooke and Linda Castro said they were walking to lunch in Hillcrest and noticed the art, then changed their route to walk by it.“We saw this so we decided we needed to walk down the alley to see everything,” said Linda.They said they could envision the space with lights and would welcome the addition because it would highlight the art, but also bring a level of safety.“I think this would become a more popular area just because of the artwork and the lighting,” said Linda.Donations to the project can be made here. Nicholls said the light project will cost about ,500 and any leftover donations will be used to continue adding murals to blank walls in the area.For Stillman, the addition of the outdoor space behind his business is a welcome project during a stressful time.“I think that art always warms our hearts and for a community to have this space, I think is really important in these times that are so challenging,” said Stillman. 2189

SAN DIEGO, Calif. (KGTV) - Skies across the country filled with messages of change this Fourth of July weekend, including in San Diego. In Plain Sight is a national movement by about 80 artists with a goal of abolishing Immigration Detention Centers. Artists designed messages, then air crews drew those words in the sky.In San Diego, Pedro Rios, the American Friends Service Committee Director, said doing it on the holiday weekend was intentional.“As we’re contemplating the meeting of this weekend and this holiday, we should take into consideration what independence really means when there are tens of thousands of people that are detained right now,” said Rios.Locally, five locations were chosen over spots that have immigration facilities, from downtown down to the border. Individual artists were assigned to each location to create the specific messages.“We need to have conversations that question that and I think this artistic endeavor, In Plain Sight, is part of a larger dialogue of how we converse, of whether detention and incarceration is a best representation of who we are as people living in the United States,” said Rios, a Chula Vista native. 1173
