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.
Deficit Hits $738.6 Billion in First 8 Months of Fiscal Year
The U.S. budget deficit grew to $738.6 billion in the first eight months of the current fiscal year – an increase of $206 billion, or 38.8%, over the deficit recorded during the same period a year earlier. Bloomberg’s Sarah McGregor notes that the big increase occurred despite a jump in tariff revenues, which have nearly doubled to $44.9 billion so far this fiscal year. But that increase, which contributed to an overall increase in revenues of 2.3%, was not enough to make up for the reduced revenues from the Republican tax cuts and a 9.3% increase in government spending.
Tweet of the Day: Revenues or Spending?
Rep. Kevin Brady (R-TX), ranking member of the House Ways and Means Committee and one of the authors of the 2017 Republican tax overhaul, told The Washington Post’s Heather Long Tuesday that the budget deficit is driven by excess spending, not a shortfall in revenues in the wake of the tax cuts. The Wall Street Journal’s Kate Davidson provided some inconvenient facts for Brady’s claim in a tweet, pointing out that government revenues as a share of GDP have fallen significantly since 2015, while spending has remained more or less constant.
Chart of the Day: The Decline in IRS Audits
Reviewing the recent annual report on tax statistics from the IRS, Robert Weinberger of the Tax Policy Center says it “tells a story of shrinking staff, fewer audits, and less customer service.” The agency had 22% fewer personnel in 2018 than it did in 2010, and its enforcement budget has fallen by nearly $1 billion, Weinberger writes. One obvious effect of the budget cuts has been a sharp reduction in the number of audits the agency has performed annually, which you can see in the chart below.
Number of the Day: $102 Million
President Trump’s golf playing has cost taxpayers $102 million in extra travel and security expenses, according to an analysis by the left-leaning HuffPost news site.
“The $102 million total to date spent on Trump’s presidential golfing represents 255 times the annual presidential salary he volunteered not to take. It is more than three times the cost of special counsel Robert Mueller’s investigation that Trump continually complains about. It would fund for six years the Special Olympics program that Trump’s proposed budget had originally cut to save money,” HuffPost’s S.V. Date writes.
Date says the White House did not respond to HuffPost’s requests for comment.
Americans See Tax-Paying as a Duty
The IRS may not be conducting audits like it used to, but according to the agency’s Data Book for 2018, most Americans still believe it’s not acceptable to cheat on your taxes. About 67% of respondents to an IRS opinion survey “completely agree” that it’s a civic duty to pay “a fair share of taxes,” and another 26% “mostly agree,” bringing the total in agreement to over 90%. Accounting Today says that attitude has been pretty consistent over the last decade.
