How IBM Is Making Your Passwords Useless
For years, quantum computing has been hailed as a technology that could change the way the modern world works, but a long-standing technical issue has kept that potential from being realized. Now, in a paper published in the journal Nature last week, IBM scientists have taken a big step (see how I avoided the temptation to make a pun there?) toward solving that problem — and while it could represent progress toward making quatum computers real, it also could mean that current cybersecurity standards will soon be much easier to crack. In other words, your passwords could be obsolete soon.
The power of quantum computing has some obvious appeal: The increase in processing power could speed up research, especially in big data applications. Problems with large datasets, or those that need many millions (or billions, or more) of simulations to develop a working theory, would be able to be run at speeds unthinkable today. This could mean giant leaps forward in medical research, where enhanced simulations can be used to test cancer treatments or work on the development of new vaccines for ebola, HIV, malaria and the other diseases. High-level physics labs like CERN could use the extra power to increase our understanding of the way the universe at large works.
But the most immediate impact for the regular person would be in the way your private information is kept safe. Current encryption relies on massively large prime numbers to encode your sensitive information. Using combinations of large prime numbers means that anyone trying to crack such encryption needs to attempt to factor at least one of those numbers to get into encrypted data. When you buy something from, say, Amazon, the connection between your computer and Amazon is encrypted using that basic system (it's more complicated than that, but that's the rough summary). The time it would take a digital computer to calculate these factors is essentially past the heat death of the universe. (Still, this won't help you if your password is password, or monkey, or 123456. Please, people, use a password manager.)
Quantum computing, however, increases processing speed and the actual nature of the computation so significantly that it reduces that time to nearly nothing, making current encryption much less secure.
The IBM researcher that could make that happen is complicated, and it requires some background explanation. For starters, while a "traditional" computing bit can be either a 0 or a 1, a quantum computing bit can have three (or infinite, depending on how you want to interpret the concept) states. More specifically, a qubit can be 0, 1, or both.
Up until now, the both part of that caused some problems in realizing the power of quantum computing.
Apparently — and you'll have to take this on faith a bit, as it hurts my head to think about it — the both state can switch back to either 0 or 1 at any given point, and sometimes incorrectly, based on the logic in the programming. Think about when your phone freezes up for a second or two while you're matching tiles. This is its processor handling vast amounts of information and filtering out the operations that fail for any number of reasons, from buggy code to malware to basic electrical noise. When there are only the two binary states, this is a process that usually happens behind the scenes and quickly.
The hold-up with quantum computing up until now is that the vastly greater potential for errors has stymied attempts to identify and nullify them. One additional wrinkle in this reading quantum states is familiar to anyone with basic science fiction knowledge, or perhaps just the ailurophobics. What if the action of reading the qubit actually causes it to collapse to 0 or 1?
The very smart people at IBM think they've solved this. The actual technical explanation is involved, and well beyond my ability to fully follow, but the gist is that instead of just having the qubits arrayed in a lattice on their own, they are arranged such that neighbors essentially check each other, producing the ability to check the common read problems.
That opens the door to further quantum computing developments, including ones that will make your password a thing of the past. So, does this mean that you need to start hoarding gold? No, not yet. And hopefully before quantum computing reaches commercial, or even simply industrial/governmental levels, a better cyber security method will be in place. Or the robots will have already taken over. I for one welcome them.
Big Ad Buys to Push Tax Reform
Two conservative groups are spending millions to promote an overhaul of the tax code.
The American Action Network announced Thursday that it will spend $2 million on a new TV ad featuring a Midwestern mom who says her family is “living paycheck to paycheck” and that a middle class tax cut would give them “piece of mind.” The ad will air in 28 congressional districts currently held by Republicans. Americans for Prosperity, backed by the Koch brothers, will spend $4.5 million on ads that promote tax reform while criticizing three red-state Democratic senators -- Claire McCaskill (MO), Tammy Baldwin (WI) and Joe Donnelly (IN).
Some States Will See Dramatic Obamacare Price Hikes in 2018
Premiums for Affordable Care Act policies are set to rocket higher in many places in 2018. Many of the rates for next year won't be made public until November, but The New York Times found that Georgia has already approved increases of up to 57.5 percent, while the average rate in Florida will jump by about 45 percent and the average in New Mexico will climb by 30 percent. Minnesota, on the other hand, announced this week that a new state reinsurance program has helped stabilize rates and price changes for individual plans in the state will range from a decrease of 38 percent to an increase of 3 percent.
Confusion stemming from the White House and Congress, including uncertainty about whether the Trump administration will continue to make cost-sharing payments to insurers, is largely driving the increases. Keep in mind, though, that about 85 percent of people who buy insurance through Obamacare exchanges won’t feel the price hikes because their plans are subsidized — but the federal government will have to shell out more for those subsidies.
A Tax Reform 'Game Changer'?
The National Association of Home Builders says it's open to changes to the mortgage-interest deduction — a major policy shift that could have significant implications for the Trump administration's proposed tax reform, Politico's Lorraine Woellert reports. The break benefiting homebuyers was preserved as part of the tax framework released last week, but the reform plan also calls for increasing the standard deduction, a shift that would make the mortgage interest deduction less valuable. The National Association of Realtors last week criticized the administration's plan, even though it left the mortgage tax break in place. "This proposal recommends a backdoor elimination of the mortgage interest deduction for all but the top 5 percent who would still itemize their deductions," the group's president said.
Warren Buffett: Eliminating the Estate Tax Would Be a ‘Terrible Mistake’
The world’s second-wealthiest man is worth about $75 billion, but he isn’t worried about the government taking a bite out of his estate after he’s gone. In fact, Buffett thinks the estate tax, which applies to just a few thousand estates a year, is a reasonable way to allocate resources, especially in a society in which the rich have gotten much richer over the last few decades. Buffett’s main concern is the emergence of “dynastic wealth” that “goes totally against what built this country, what this country stands for.” In an interview Tuesday, Buffett criticized the latest GOP proposal to get rid of the estate tax: "If they pass the bill they're talking about, I could leave $75 billion to a bunch of children and grandchildren and great-grandchildren. And if I left it to 35 of them, they'd each have a couple billion dollars ... Is that a great way to allocate resources in the United States?” (CNBC)
Treasury Pulls a Paper That Contradicts Mnuchin’s Corporate Tax Argument
The Treasury Department has taken down from its website a 2012 analysis that found that business owners and shareholders — not workers — bear most of the burden of corporate taxes. The findings of the report run counter to the argument Treasury Secretary Steven Mnuchin has been making in selling the benefits of a reduction in the corporate tax rate. The Trump administration’s tax reform framework calls for dropping the corporate rate from 35 percent to 20 percent.
The 2012 report from the Office of Tax Analysis found that “workers pay 18 percent of the corporate tax while owners of capital pay 82 percent” — figures that are “in line with many economists’ views and close to estimates from the nonpartisan Joint Committee on Taxation and Congressional Budget Office,” according to The Wall Street Journal.
A Treasury spokeswoman told the Journal: “The paper was a dated staff analysis from the previous administration. It does not represent our current thinking and analysis.”
Jason Furman, who was chairman of President Obama’s Council of Economic Advisors, tweeted that the goal of the technical paper series that included the removed study “was to be more transparent about the methodology Treasury used for its modeling and analysis.”
Treasury website has 40+ yrs of Tax Working & Technical Papers. This is the only one removed https://t.co/QzLTSHderk https://t.co/MFZRd7HoFQ
