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) -- Three people are dead following a crash on Interstate 805 in University City.The California Highway Patrol says the crash happened in the northbound lanes of I-805 at Miramar Road around 4:30 p.m.According to CHP, the crash happened after a wrong-way driver drove onto the road at a high rate of speed."Through the investigation, we will try to determined where this individual, if they got on the freeway the wrong way, where they got on," CHP Officer, Jake Sanchez said. Hector Puga was on his way to Los Angeles when the car in front of him combusted. He somehow managed to escape the crash and flames. "All I can do is hold onto the steering wheel and run over everything that exploded," Puga said. He escaped with just a flat tire and broken windshield.10News also spoke to a pair of sisters who had just finished up a fun day of shopping at UTC Mall when hopped into their car. Minutes later, they endured a near-death experience. "It was like a scene from a movie," she said. "All the cars were stopping. There was smoke. Fire. Loud noise. As soon as I look up in front of me, that car other there was flying and tumbling down the freeway."They said the driver of the flipped over SUV managed to crawl out of the car.  The survivors carried him to the shoulder, where an ambulance later picked him up. CHP said he endured broken bones, but is expected to recover. All lanes on the interstate were closed for several hours following the crash. Click here for traffic updates. Though it remains unclear if police are investigating the scene as connected to the incident on I-805, Thursday night police investigated a scene at Ashley Falls Elementary School in Carmel Valley. That's where a car rammed a campus gate, according to police. Students tell 10News the driver of a sports car tried to drive onto the soccer field before peeling out of the parking lot. 10News asked the CHP and SDPD whether the cases are connected, but have not gotten confirmation.Watch live video from the I-805 scene below: 2107

SAN DIEGO (KGTV)-- Thousands of members of the LGBTQ Community and their allies lined the streets of Hillcrest to celebrate the San Diego Pride Parade Saturday morning. More than 200 floats were on display at this year's event. We asked the crowd, "What does "Pride" mean to you?""It means finally being able to live out and proud.""It's the freedom to celebrate who we are.""Love our neighbor as ourselves and love God!"Some have been coming to the San Diego Pride Parade for decades. "Oh my gosh, she's been 26 years of marching in pride with me," Dana Harwood said of her mother. "...And I love my lesbian daughter!" her mother, Bobbi said. For others, this year's parade is their debut to the world. "Fours months ago, I started my transition," Grace McBride said. "I am just so happy now that I came out to be authentic."For 55 years, people called her Dale. But today, she is proudly Grace."Dale was struggling. Dale was a Marine. Dale worked for the cable company, and anymore now I just want to share the love," McBride said. It has been a long struggle for the LGBTQ community. The most notable moment was the Stonewall Riots in 1969, where New York Police raided LGBTQ members staying at the Stonewall Inn. "Stonewall gave us a sense of freedom. A sense of power," Drag Queen Vera Del Mar said.Vera Del Mar grew up in National City but now lives in Tucson. She made it a point to make it back to her hometown Pride this year."I had to show off my new hairdo!" she said.What was once considered 'underground' or 'shameful' has now become part of mainstream culture, even mainstream media. This year, many familiar faces of the 10News team joined the 10News float and greeted parade-goers. 14-year-old Alexis Engelmann came out as lesbian last year. She says she is lucky to have her entire family in her corner. "It's cool because it's not really different at all," her younger brother Mile said. "We just like to support her and help her succeed in life."Like the thousands of people at the parade, Alexis is proud. She is celebrating, not hiding her Pride. "I love them [my family] so much, and I am so grateful," Alexis said. If you missed the Pride Parade this morning, there are plenty of other things to do around Hillcrest. The Pride Festival continues throughout the weekend. Tonight's headliner is King Princess, and tomorrow night's headliner is LGBTQ trailblazer and iconic rocker Melissa Etheridge. 2427

SAN DIEGO (KGTV)-- Saturday marks the end to the San Diego Zoo's longest closure in its 103-year history. For the first time since the COVID-19 pandemic forced a shutdown in mid-March, the zoo is back open. Visitors were happy to return to one of our city's jewels, even with some changes.For the last three months, visitors have been anxious to come to the grand reopening on Saturday."The turtles are kind of big and funny," laughed little Kitara. The grade-schooler celebrated her birthday two days ago, and Saturday was her first big outing since.The zoo has made some modifications to operations and guest rules:Face coverings are required for all guests over two years of agePeople must practice social distancingThere are limited dining and shopping, overall reduced park hoursOperating at 50% guest capacityLimited guest parkingMembers and guests will not be allowed to leave the parks and re-enter on the same dayOne-way path adjustments, plexi-glass, and barriers to help guests navigate safelyIncreased number of hand-washing and sanitizing locationsRobust cleaning routineThroughout the park, staff members will guide people to move along to discourage crowding."I think they help people maintain social distancing really well," pass holder, Valerie Warren said. "They're very informative, and have all sorts of information for everybody on where to go and what to do, so I think they're doing an amazing job."The most significant change guests may see is at the primates exhibit."It can affect some of our animals," Sofia Springer, the zoo's Operations Manager said.Scientists say primates have been known to catch some human respiratory illnesses. Their immunity to COVID-19 is not certain. But the zoo isn't taking any chances."We've provided barriers and one-way pathways to keep the guests from getting too close to those areas."But there are many other exhibits where you can get up close to the animals. For visitors like little Kitara, that is what the San Deigo Zoo is all about."I like it, and it smells disgusting in there, but I still like it!" she laughed.The Zoo's Guided Bus Tour, Kangaroo Bus, and Skyfari Aerial Tram, as well as the Safari Park's Africa Tram, will remain closed during the first reopening phase to comply with social distancing protocols.Click HERE for more information on the San Diego Zoo's reopening. 2357

SAN DIEGO, Calif. (KGTV) -- Sixteen people are dead and hundreds are still hospitalized as the City of San Diego continues to battle a Hepatitis A. The majority of them are homeless.Tents belonging to the homeless were back up in downtown just two days after the city sprayed down streets and sidewalks to control the outbreak. David Ross is known as "the waterman" in downtown. He is an advocate for the homeless and regularly passes out water to those living on the street. He thinks the city could have prevented the homeless outbreak by installing portable bathrooms. RELATED: San Diego adding 3 new homeless shelters, look to curb hepatitis A outbreakHepatitis A spreads by person to person contact. Right now, the homeless don't have a place to wash their hands or go to the bathroom. Ross thinks the problem will continue until people have a place to wash their hands. 10News reached out to the city about the possibility of installing portable restrooms and this is what they said via email: 1027
