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 FRANCISCO (AP) — Facebook left millions of user passwords readable by its employees for years, the company acknowledged Thursday after a security researcher exposed the lapse .By storing passwords in readable plain text, Facebook violated fundamental computer-security practices. Those call for organizations and websites to save passwords in a scrambled form that makes it almost impossible to recover the original text."There is no valid reason why anyone in an organization, especially the size of Facebook, needs to have access to users' passwords in plain text," said cybersecurity expert Andrei Barysevich of Recorded Future.Facebook said there is no evidence its employees abused access to this data. But thousands of employees could have searched them. The company said the passwords were stored on internal company servers, where no outsiders could access them.The incident reveals yet another huge and basic oversight at a company that insists it is a responsible guardian for the personal data of its 2.2 billion users worldwide.The security blog KrebsOnSecurity said Facebook may have left the passwords of some 600 million Facebook users vulnerable. In a blog post , Facebook said it will likely notify "hundreds of millions" of Facebook Lite users, millions of Facebook users and tens of thousands of Instagram users that their passwords were stored in plain text.Facebook Lite is a version designed for people with older phones or low-speed internet connections. It is used primarily in developing countries.Last week, Facebook CEO Mark Zuckerberg touted a new "privacy-focused vision " for the social network that would emphasize private communication over public sharing. The company wants to encourage small groups of people to carry on encrypted conversations that neither Facebook nor any other outsider can read.The fact that the company couldn't manage to do something as simple as encrypting passwords, however, raises questions about its ability to manage more complex encryption issues — such in messaging — flawlessly.Facebook said it discovered the problem in January. But security researcher Brian Krebs wrote that in some cases the passwords had been stored in plain text since 2012. Facebook Lite launched in 2015 and Facebook bought Instagram in 2012.Recorded Future's Barysevich said he could not recall any major company caught leaving so many passwords exposed internally. He said he's seen a number of instances where much smaller organizations made such information readily available — not just to programmers but also to customer support teams.Security analyst Troy Hunt, who runs the "haveibeenpwned.com" data breach website, said that the situation is embarrassing for Facebook, but that there's no serious, practical impact unless an adversary gained access to the passwords. But Facebook has had major breaches, most recently in September when attackers accessed some 29 million accounts .Jake Williams, president of Rendition Infosec, said storing passwords in plain text is "unfortunately more common than most of the industry talks about" and tends to happen when developers are trying to rid a system of bugs.He said the Facebook blog post suggests storing passwords in plain text may have been "a sanctioned practice," although he said it's also possible a "rogue development team" was to blame.Hunt and Krebs both likened Facebook's failure to similar stumbles last year on a far smaller scale at Twitter and Github; the latter is a site where developers store code and track projects. In those cases, software bugs were blamed for accidentally storing plaintext passwords in internal logs.Facebook's normal procedure for passwords is to store them encoded, the company noted Thursday in its blog post.That's good to know, although Facebook engineers apparently added code that defeated the safeguard, said security researcher Rob Graham. "They have all the proper locks on the doors, but somebody left the window open," he said.___Bajak reported from Boston. 4018

SAN DIEGO, Calif. (KGTV) - Professional lacrosse player Jules Heningburg joined the San Diego Seals and played with the team until the season was cut short due to coronavirus. The athlete said his aunt works for the CDC, so he’s taken the virus seriously since the beginning.“I was following the rules there, I was wearing a mask, socially distancing, washing my hands, I really didn’t see anyone other than my roommate,” said Heningburg.He said even when some businesses moved further into reopening in San Diego, he continued his carefulness.“I had to just make sure I was going to keep myself safe, so I continued to follow quarantine on my own protocol, not going out. I didn’t go to bars, I didn’t do anything like that, I didn’t go to any restaurants,” he said.Then, as rules continued to relax, he went to one single birthday party, then found out later that someone at the party had tested positive. A few days later and he knew something was wrong with him.“I was having a conversation and all of a sudden I got really tired, like mid talk at 6:30 at night,” he said.He tested positive and said at first his symptoms were not terrible. Once he was not contagious, he traveled to Utah to play in a lacrosse league, and since he had previously tested positive, he had to do extra doctors visits. That’s when he realized the impacts on his health were worse that he thought. His oxygen levels quickly fell during tests.“As a professional athlete and someone who is in really good shape, when you start moving around that level should not drop. When I started to walk around those levels started to drop,” he said.He said with levels dropping this rapidly, he had an increased risk of cardiac arrest. He then realized how close he came to losing his life, thankful he had done the extra tests that showed he had a problem.“I followed all the rules and I was still put in a situation and exposed to it and could have died,” he said.This meant exercising and playing were not an option, so ultimately Heningburg has to sit out from the Utah league. He came back to San Diego to rest and heal, then will figure out when it’s safe for him to play again.He said he wants to send a message to San Diego that the virus is dangerous and he, a young and athletic man who almost lost his life, is proof. 2306

SAN DIEGO, Calif. (KGTV) -- The family of Crystal Odom filled a San Diego courtroom Monday morning to hear a judge sentence the man convicted of killing Odom in a drive-by shooting in 1995. The judge sentenced Aswad Walker to 15 years to life for Odom's murder, plus three years for gang ties. He was convicted of second-degree murder back in February for Odom's death. Two previous trials had ended in hung juries. Odom's parents spoke before the sentencing. Her mother called Walker a coward and told him he would get what he deserved in prison. When Odom's father, James Odom, spoke, the family became very emotional, tears and sobs could be heard throughout the courtroom. Odom said a burden was lifted off his shoulders and that the sentencing marked an end to a long ordeal. At the time of the shooting, Crystal was with her then boyfriend and her 10-month-old daughter. Her daughter and boyfriend were unhurt. 959

SAN DIEGO (KGTV)-- San Diego Pride festivities kicked off in the Hillcrest neighborhood Friday afternoon at the iconic Gay Pride Flag on University Ave. and Normal St. Thousands celebrated this year's theme, Stonewall 50: A Legacy of Liberation. The Glitz and Glam and the fabulous outfits at Pride are a product of dark times. "In 1969, being gay was considered a mental illness," San Diego Pride Executive Director Fernando Lopez said. "And the LGBT community was persecuted and prosecuted through legal and social systemic oppression and discrimination."In the summer of 1969, New York Police raided the Stonewall Inn, a place known as a safe spot for the LGBT community. Veronica Zerrer remembers watching the violence on the news. "When Stonewall happened, I was 12 years old, and I was just hitting puberty," Zerrer said. It was a turning point in her life because back then, she says she was hiding. "My name was Ronald," Zerrer said. "In fact, I have a really interesting story. I grew up being called Ronnie."Ronnie served in the U.S. Army for two decades and retired as a Major. The next year in 1999, Ronnie became Veronica. "Before I came out, I tried to be the person that I thought my family and society thought I should be, instead of what was inside my heart," Zerrer said.Fifty years later, San Diego Pride is honoring the rioters at Stonewall, who stood up against police prejudice. "This year, we are 'Stonewall 50: A legacy of liberation.' And the celebrations today, tomorrow and all weekend long are really going to reflect back in honor of our Stonewall generation. We'll talk about the legacy that we are all a part of, and what we need to do to recommit ourselves for the next generation," Lopez said. It is a big 'thank you' to their courage that inspired future generations. "Because you're not allowed by society to be who you really are, you have to almost 'perform' gender. Whereas right now, I'm expressing my gender," Zerrer said.  1976
