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) — A U.S. appeals court won't immediately let President Donald Trump end an Obama-era program shielding young immigrants from deportation.A three-judge panel of the 9th U.S. Circuit Court of Appeals on Thursday decided to keep in place an injunction blocking Trump's decision to phase out the Deferred Action for Childhood Arrivals program.Lawsuits by California and others challenging the Trump administration's decision will continue in federal court while the injunction remains in place.RELATED: San Diego Dreamers facing 'nightmare' after Trump decisionDACA has protected some 700,000 people who were brought to the U.S. illegally as children or came with families that overstayed visas.In January, U.S. District Judge William Alsup rejected the argument that then-President Barack Obama had exceeded his power in creating DACA.The Trump administration has said it moved last year to end the program because Texas and other states threatened to sue, raising the prospect of a chaotic end to DACA.RELATED: Trump administration asks SCOTUS to step in on DACA?cases 1093

SAN DIEGO, CA (KGTV) — It was a struggle that paved the way for American women today, giving those forced to be silent, a voice: the right to vote."It took 72 years from 1848 until 1920 to get the 19th Amendment added to our constitution," said Anne Hoiberg, Board President of the Women's Museum of California. She refuses to forget what it took to get here and the women who fought not only for the right to vote, but for equality."Elizabeth Cady Stanton and Susan B. Anthony they were really the team," she said while pointing to photos that line an exhibit inside of the museum at Liberty Station. "Carrie Chapman Catt started the League of Women Voters.""We have to credit Elizabeth Cady Stanton and Lucretia Mott two Quakers, two abolitionist, who were determined that women needed to have the right to vote, but they also needed other rights," said Hoiberg. "They needed the right to divorce, to go to college, to become professionals like a doctor or a lawyer."Because of those women and many more, the protests, marches, arrests and tireless work, women here in San Diego heading to the polls know their votes count. Their opinions matter. Their voices are heard."That means a lot to me," said voter Linda Garcia. "It's terrible that it took so long to even happen.""We have rights and we should take advantage of those rights," said Diana Romero, another women who always votes. "Hopefully a lot of women do take advantage of those rights and vote."As we celebrate the centennial of suffrage this year, "The Power of the Ballot Box" exhibit will remain on display through the month of march at the museum in Liberty Station.Hoiberg said the goal is to make sure everyone, especially the younger generations, know how far we have come and that so much is possible, even when the fight isn't over."Little girls need to see that women can achieve anything," she said. "It is important for all of us to just remember those courageous women, and many, many men who really fought hard so women can get the right to vote." 2036

San Diego (KGTV)- Hygiene continues to be a struggle for those living on the streets, especially during the pandemic. Non-profit Duwara Consciousness is helping the homeless gain access to a hot shower.The non-profit uses its food trailer to feed the homeless. On average, they provide about 1,500 meals per week."Our distribution network currently runs as far as San Ysidro and as far north as Carlsbad," says Harisimran Khalsa.But as we continue to experience the COVID-19 pandemic, Khalsa says access to a hot shower was limited for those in need. This prompted her and partner, Davinder Singh, to move forward with their idea of a shower trailer."Hygiene access is just not as frequent. So you do end up coming down with more bugs, more viruses," says Khalsa. "We think that this is really a time when we have to focus on hygiene for our homeless population."The shower trailer contains seven individual stalls, including one that is ADA compliant."It's really critical for our guests that they have a secure environment in which to shower."Khalsa says about 20 people can use the shower per hour. The stalls are cleaned after each use following CDC guidelines.The trailer comes equipped with sinks for people to wash their hands, shave or brush their teeth. It also has laundry services. The non-profit partners with other organizations to provide space and water.Duwara Consciousness plans to launch the shower trailer on Friday officially, but so far, they say users have been grateful for a simple hot shower. 1525
