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 - Controversial Heisman Trophy winner Johnny Manziel made an unexpected appearance in San Diego Thursday.Manziel threw passes during the "Pro Day" at the University of San Diego, where NFL scouts gathered to evaluate some Toreros seniors. They also took notes on the former Texas A&M star.Manziel, who currently lives in the Los Angeles area, has been working with San Diego-based quarterback guru George Whitfield, Jr. on his game.He flamed out after just two seasons with the Cleveland Browns.Manziel’s personal troubles include an arrest for disorderly conduct, an altercation with his girlfriend, and time in rehab for an unspecified issue. He admitted to depression and self-medicating with alcohol during his time in the NFL.Manziel just celebrated his first wedding anniversary and told San Diego-based KGTV he’s too busy to get into trouble.He said he’s hoping to sign with a pro team and resume his career. 952

SAN DIEGO (KGTV)— Rady Children’s Hospital announced their partnership with Children's Specialized Hospital in New Jersey, to expand its opioid-free Pain Management Program.10News met 17-year-old Jasper Neale at Rady Children's Hospital. Neale said in the summer of 2014, he was at a junior lifeguards camp at Moonlight State Beach in Encinitas. When he was running on the sand, he fractured his heel. His family thought it was a straight forward injury. But the pain started to spread everywhere, making him immobile.“It went up my calf, and my whole leg and calf were getting really swollen,” Neale said. “It started with like a three out of ten, but it became a ten out of ten for my whole body.”His x-rays showed recovery, but his pain was not going away. The injury puzzled locals doctors. "They kind of just said, ‘We're not sure.’ This is the weirdest thing I've ever seen,” Neale said. Their last hope was the Children's Specialized Hospital in New Jersey, where they had an advanced chronic pain management program. There, the specialists told him his diagnosis: complex regional pain syndrome."You never take any drugs. You literally have nothing but yourself,” Neale said. Unlike traditional methods of pain relief, this program does not use any opioids.“People want a quick fix. The magic pill. The magic surgery to make everything get better, but most of the time, that's not available,” Andrew Skalsky, Division Chief of Rehabilitation Medicine at Rady Children’s Hospital, said. They have a tough love approach, combined with alternative therapies."I came in being unable to walk, and the very next day, they forced you to run. They forced you to swim."“Unfortunately with a lot of chronic pain patients, they actually have to somewhat create more pain to make themselves better, but then also giving them the emotional and psychological tool kit to cope with that pain,” Skalsky said.Today, Rady Children’s Hospital announced they too will be adopting this program, so in the future, patients like Neale can get the treatment they need closer to home. For Neale, it was a seven-week treatment in New Jersey that fixed his chronic nerve pain. He came back to Encinitas, not hooked on drugs. There were no side effects. "From the day I left to now, I can do everything I want to do,” Neale said. Neale’s recovery led to the discovery of a new passion. The 6’8” senior at San Dieguito Academy is now a star volleyball player. In the fall, he will play for the University of Toronto."Going from being completely dysfunctional, to being a fully functioning human, with only doing it through physical therapy and natural ways is amazing,” Neale said. Ready Children’s Hospital said this approach is not for all treatments. This one focuses solely on chronic pain. 2782

San Diego, CA (KGTV)- Some high school students in the Grossmont Union High School District will return to partial in-person learning starting on September 29.Sixty-eight percent of parents surveyed districtwide wanted their high school students to return to an in-person, blended learning model, while 32 percent wanted their students to stay in full-time distance learning from home.The district is moving forward with both options.Starting Tuesday, some students will be back on campus with limitations."Students have to be divided into smaller groups," said Theresa Kemper, the district's superintendent.If parents chose the blended learning model, their student has been assigned to Group A, Group B, Group C, or Group D, based on factions like students per household, transportation needs, and course schedule."They each will come to school one day a week," she said.The group placement determines which day the students will come to campus; they will be learning from home the rest of the time.The district created a roadmap for reopening, which includes five levels."We want to make sure that we're really confident with new routines that have been established, we want to make sure the county health conditions are continuing to improve," said Kemper.All schools in the district have been operating at Level 1, which is strictly distance learning.Level 2 begins next week and allows students to learn on campus one day a week, with 25 percent of the campus population, in class sizes of eight to twelve students."Our Special Education academies and alternative schools are also starting at Level 2, but will attend two days a week instead of one," she said.All students will be screened and have their temperatures checked before entering the classroom, teachers, and staff will be tested for COVID-19 regularly, and everyone will be required to wear facial coverings.The schools will also be deep cleaned each day, and students will be physically distanced from one another."If everything looks good, after about two weeks, we could potentially announce going to the next level," said Kemper.By level five, students will be back on campus five days a week.Kemper said the district is taking a cautious approach and has plans in place if a school needs to jump back a level at any time."If we change from two days a week to one day a week, then we already got a plan in place, and it's easy to transition to that," she said. "I want parents and students to know we are so excited to see him, there's no place like school." 2539

SAN FRANCISCO (AP) — A small wildfire broke out Sunday morning near Vallejo (vuh-LAY'-ho) with flames coming dangerously close to homes and forcing a college to evacuate at the northeast end of San Francisco Bay.A live broadcast on KGO-TV shows the fire on both sides of Interstate 80 and homeowners using hoses on a hillside to try and fight it.The fire forced the freeway to close and the California State University Maritime Academy to issue an evacuation order.The wildfire halted traffic at the Carquinez Bridge toll booth as the freeway became shrouded in thick smoke.Vallejo is 55 miles (88.5 kilometers) south of Geyserville where a massive wildfire forced 180,000 people to flee their communities. 714
