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 — Football icon Drew Brees gave a Temecula, California teenager the gift of a lifetime this week.The New Orleans Saints QB surprised Alex Ruiz at a Del Mar flag football event with a prosthetic leg."Surprise," Brees yelled into a microphone.Ruiz suffered a severe leg injury while playing football in October 2017. The quarterback at Linfield Christian School in Temecula was rolling out of the pocket when he was tackled and injured. The injury forced an amputation of Ruiz's foot.Brees presented the teen with a walking prosthetic Friday."If there's anything above cloud nine that's where I'm at right now," Ruiz said, all smiles after Brees asked him what he planned to do first with his new prosthetic.Brees added that once Ruiz gets the hang of it, he'll receive an athletic prosthetic as well with which to begin athletic training. But that didn't stop the two quarterbacks from sharing a quick pass."It's going to allow him to walk around, get around, and then eventually get to the point where he's able to play football again," Brees said. "Because ask him right now and there's no denying the look in his eye that that's what he wants to do." 1250

SAN DIEGO, Calif. (KGTV) - A new group of leaders has the California GOP ready to take on the 2020 elections and rebound from a disastrous 2018 cycle.Over the weekend, the GOP elected Jessica Patterson as their state-wide Chair. She's the first woman and first Latina to ever hold the top spot in the state party.They also elected a Taiwanese immigrant, Peter Kuo, as Vice-Chair. And the new Treasurer, Greg Gandrud, is openly gay.Analysts say that gives them a more diverse group of leaders that can reach out to more voters across the state.But newly elected Secretary Randy Berholtz, who lives in San Diego, says their election within the party had nothing to do with demographics."I think what the delegates did is pick the best person for each of the positions," Berholtz says. "It just so happens that the people were of different ethnicities and sexes and ages and everything else."Berholtz says he saw an energized party at the convention, ready to bounce back from 2018.In that election, Republicans lost 7 seats in the US House of Representatives. Loses in local legislative races also gave democrats a super-majority in the California House and Senate. Republicans only hold 19 or 80 seats in the House and 11 of 40 seats in the Senate.The election also continued a streak of no Republicans winning statewide office since 2006.Berholtz says a strong Republican party is a good thing for the state."California needs to have a good second party," he says. "If not, nobody's watching the party in power. And we want to tell the voters that we're watching."In the last election, Republicans only made up 24% of the registered voters. That put them behind Democrats and people who registered as "No Preference."Political analyst John Dadian says it could take as long as 10 years for the GOP to turn that around."The main strategy has to be to bring some of those, 'prefer not to state' voters back," says Dadian. "It's all in the messaging, because California isn't just a blue state, it's a deep-blue state."Berholtz says his party will use a focus on family, personal initiative and good government to turn the tide. He also says they'll look to a more grass roots campaign to try and elect leaders from the bottom-up."We're energized right now," he says. "We're all going out and speaking, finding great candidates, doing voter registration, improving our message and just telling people in California that there is a viable alternative and we have not given up on you." 2489

San Diego, Calif. (KGTV) - Season 16 of the Bachelorette was unlike any other. The original Bachelorette, Clare, fell quickly in love with one of the men on the show and left engaged to him. Then a new Bachelorette, Tayshia was brought in. San Diego local Chasen Nick was there through all of the drama, trying to vie for each woman’s heart.Chasen, who has lived in San Diego for close to ten years, said his friends submitted him for the show. He said he was brought in during the pandemic, so he knew Clare was the Bachelorette and he knew the season would be shot in a quarantined setting at a Palm Springs resort.Tayshia sent him home on the episode that aired Nov. 24 and he said looking back, he felt more of a connection with Clare.“I have to be completely honest, I’d say Clare. I didn’t really get the opportunity to progress with Tayshia and it was just a surface level connection getting to know each other,” he said.Chasen had a few heated moments during his time on the show, including calling Tayshia a “smoke show” in front of the other guys in the house. Looking back, he says he would’ve picked a different word. He said one part of the journey he would not change, though, was his interactions with Ed, another guy in the house. Chasen and Ed had a few tense moments, but Chasen said he doesn’t regret how he reacted.“I wish Ed would have stopped and surrendered when I apologized but some people hold onto things. I think if that was different than things could’ve been different with my progression with Tayshia and our relationship,” said Chasen, saying he and Ed have reconciled since the show aired.Chasen said he’s happy to be back home in San Diego. He’s ready to focus on his career working as an account executive for Apex Systems, then get back into the dating world.“I’m onto bigger and better things right now, focus on myself, and I’ll be able to put myself out there eventually,” he said.He said since the show started airing, he’s received support from his community and strangers in the San Diego area.“So much support and love from everyone. I’ve been recognized in public and don’t be afraid to come up to me and say hi. I’d love to talk to anyone. It’s kinda cool, it’s a different feeling,” he said, referring to his newfound fame.Many Bachelor franchise alum end up on the spinoff Paradise show, where they try a second chance at love, and he said he would be open to that if the network asked him to join.“If they asked me, I’m pretty sure I’d go,” he said. 2505

SAN DIEGO (KGTV)-- The tenants of two galleries in North Park tell 10News the new owner of their building has raised the rent so high they're been left with no choice but to leave. Owners at The Studio Door and Good Friday will both be gone from their current location on 30th Street by the end of the summer. "It was devastating we've been searching trying to find something new another space but the rents are just so high right now, " said Chris Smith, who has been with The Studio Door for nearly four years.Smith says the rent went from ,000 a month to nearly ,000. He says the galleries were some of the only left in the area."There used to be a lot of artists and art galleries here in North Park," he said. "That's what really built up North Park to be what it is and as the rents went up they all just get pushed out." So far there's no word on what will take over the spaces once the current tenants are out. 965
