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 64-year-old man is recovering after he was beaten in Kearny Mesa by a group of street racers so severely he had a brain bleed and fractured disk. "I felt my RV jostling around, like maybe they were standing on my bumper, so I got out and went around back to look and I look up and someone's standing on my RV," said the victim, who did not wish to be identified.Police said the beating happened on June 28 around 9:30 p.m. A group of street racers arrived in the area for an apparent “meet up” and gathered into a large group. Multiple vehicles arrived at the location and began doing “burn-outs” in the street. Some members of the group climbed on top of the victim’s RV. When the victim walked out of his vehicle to confront them, three of the men attacked him. Another man stole the man's phone from his pocket as he was lying on the ground unconscious. "The last thing I remember is one of his buddies jumping out and I don’t know what happened after that; I probably got hit from behind."The suspects fled the area in a grey, possibly 2003 Audi A4 sedan. The man was left lying in the street. Employees from a nearby business ran out to help him and called an ambulance. San Diego County Crime Stoppers along with investigators from the San Diego Police Department’s Eastern Division are asking for the public’s help in identifying and locating the attackers. Officers are investigating the attack as a felony battery and robbery case.Anyone with information on the identity or location of the suspects is asked to call SDPD’s Eastern Division at 858-495-7957 or the Crime Stoppers anonymous tip line at 888-580-8477. Crime Stoppers is offering up to a ,000 reward to anyone with information that leads to an arrest in this case. 1775

SAN DIEGO (KGTV)- Two years ago the Norton Sound was docked in San Diego Bay and burned for several days. Now, San Diego is hiring an outside consultant to look into the cargo fire. San Diego Fire gave 10News a statement Friday. They didn’t offer specifics about what the consultant might recommend, but say the focus is to determine if any additional equipment or training is needed when dealing with emergencies on the bay. Back in 2017, Harbor Police told 10News, “It was to my understanding that the furthest a firefighter made it was 6 feet before they started getting pushed about the fire.” Looking back, even businesses remember how horrible the smoke was over the days the fire burned, “People stopped sitting outside and employees complained about it affecting their health.” says Edgewater Grill assistant manager, Sergio Velasco. While the smoke bellowed out of the ship for nearly a week, no one was injured and the fire stayed contained and didn’t spread to any other structures. The city tells 10News the study is being done by Citygate and should be complete in the fall of 2019. 1104

SAN DIEGO (KGTV)-- Five San Diego Police officers were recognized for their exceptional bravery during the Las Vegas Massacre. Fifty-eight people died, and more than 400 others were injured in the 2017 shooting."When others run from danger, police officers run towards it," San Diego Police David Nisleit said, as he opened the awards ceremony at Miramar Air Station. On October 1, 2017, a group of San Diego Police officers was vacationing with their families in Las Vegas. They were enjoying their first year at the Route 91 Harvest Festival. But around 10 pm, the event turned deadly. "It probably wasn't fireworks or firecrackers. It wasn't just a shooting on the strip," Officer Thomas McGrath Jr. said. "We knew it was gunfire," Detective Michael Do said. "We just didn't know where it was coming from."The 1,100 bullets were fired from 32 stories up the Mandalay Bay Resort. That is when the eleven off-duty San Diego Police officers went from Vacation-mode to Action-mode. Officers Thomas McGrath, Mark Williams, Max Verduzco, Richard Barton, and Detective Michael Vo began shielding concert-goers, treating the wounded, and creating escape routes. For their heroic actions, the five men received the Department's highest decoration of bravery-- the "Medal For Valor.""I don't think I did anything special," Officer McGrath said. "I just did the same thing that I would normally do during patrol or what I have been trained to do."After helping the first group of people, Officer McGrath went back into the crowd and found Jonathan Smith, who had been shot in the neck. "I put as much fabric and shirt inside his neck to stop the bleeding," McGrath said. " I put pressure on it and did my best to get them out of that venue."He said the Department's tactical combat care training kicked it. It was an act that eventually saved Smith's life. "The bullet missed my carotid artery by a few centimeters, and it is still lodged in there," Smith said. He showed 10News his dark scar near his collar bone and said the bullet is still in a small pocket behind his heart. Without McGrath's quick actions, doctors told Smith, he would have died. Thursday, Smith drove from his home in Buena Park to not only attend the ceremony but to also give the "Lifesaving Medal" to his hero.Six other officers who were in attendance of the Route 91 festival also received recognition at Thursday's ceremony. Officers Caitlin Milligan, Eric Hansen, Bryan Johnson, William Hernandez Jr., Braden Wilson, and Detective Scott Gosnell were awarded the "Exceptional Performance Citation" for helping concert-goers escape from the venue.All of these heroic acts were made by San Diego Police Officers who were not in uniform at the time. They say the tragedy continues to inspire them to be proud members of the Department."I love my job. And I love the training that I get and being that person that can step up in times of need is always what I wanted to do," Officer Max Verduzco said. "Two years later, I still want to help people. And I think that event made me want to help more people. It made me proud to be a police officer," Det. Michael Do said. Smith told 10News the tragedy and Officer McGrath's actions inspired him to make a career change. He now works as a copier installer but hopes to one day pay it forward by becoming a law enforcement officer. 3353

SAN DIEGO (KGTV)- There's a new requirement that large California counties have to meet before they can advance on the state's color-coded COVID-19 reopening system.State health officials say the "health equity metric" will help reduce infection rates among vulnerable populations.Sunday, San Diego County health officials opened another drive up testing site in Chula Vista. Local leaders say they've been targeting disadvantaged communities with education, outreach, and testing since the start of the pandemic."About 34% of our county population is Latino, but about 66% of the cases, we saw that early on, and that's why we took the action of developing the South Bay Saturation Strategy for testing. We have sites in every community in the South Bay," said Nick Macchione, director of the Health and Human Services Agency for San Diego County.Counties with more than 106,000 residents will be divided into quartiles based on income, education, and other factors gathered in census tracts.The goal is to bring the infection rates in the most disadvantaged neighborhoods in line with the county's overall rate."Now they need to make sure that not only does their test positivity for the whole county, their adjusted case rate, but also their test positivity in the lowest quartile in the Healthy Places Index for the county all need to meet the criteria for the least restrictive tier," said Dr. Mark Ghaly, California's health secretary.Ghaly said counties will need to show that they're directing money and resources to help the communities hardest hit."It's not just the test positivity, that's the piece that helps counties move forward or slows them down in moving through the tier system, but we are working with counties on a broader strategy to focus on equity," said Ghaly.Ghaly said failing to meet the metric cannot push a county back into a more restrictive tier, but can slow it down from moving ahead.Nancy Maldonado is the President and CEO of the Chicano Federation. She welcomes the additional metric."I do think it's a good thing because I think it places emphasis on the importance of taking care of our community and taking care of our essential workers who are disproportionately communities of color," said Maldonado.Some fear it's yet another hurdle to reopening.County Supervisor Jim Desmond took to Twitter, saying if the governor wants to help disadvantaged communities, he should let them get back to work."I think it's really ironic the governor keeps those businesses and lower income folks out of jobs, and now he wants a metric to make sure we're taking care of them," said Desmond.San Diego county remains in the red tier, which is one tier away from the most restrictive purple tier. 2727
