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.
Map of the Day: Navigating the IRS
The Taxpayer Advocate Service – an independent organization within the IRS whose roughly 1,800 employees both assist taxpayers in resolving problems with the tax collection agency and recommend changes aimed at improving the system – released a “subway map” that shows the “the stages of a taxpayer’s journey.” The colorful diagram includes the steps a typical taxpayer takes to prepare and file their tax forms, as well as the many “stations” a tax return can pass through, including processing, audits, appeals and litigation. Not surprisingly, the map is quite complicated. Click here to review a larger version on the taxpayer advocate’s site.
A Surprise Government Spending Slowdown
Economists expected federal spending to boost growth in 2019, but some of the fiscal stimulus provided by the 2018 budget deal has failed to show up this year, according to Kate Davidson of The Wall Street Journal.
Defense spending has come in as expected, but nondefense spending has lagged, and it’s unlikely to catch up to projections even if it accelerates in the coming months. Lower spending on disaster relief, the government shutdown earlier this year, and federal agencies spending less than they have been given by Congress all appear to be playing a role in the spending slowdown, Davidson said.
Number of the Day: $203,500
The Wall Street Journal’s Catherine Lucey reports that acting White House Chief of Staff Mick Mulvaney is making a bit more than his predecessors: “The latest annual report to Congress on White House personnel shows that President Trump’s third chief of staff is getting an annual salary of $203,500, compared with Reince Priebus and John Kelly, each of whom earned $179,700.” The difference is the result of Mulvaney still technically occupying the role of director of the White House Office of Management and Budget, where his salary level is set by law.
The White House told the Journal that if Mulvaney is made permanent chief of staff his salary would be adjusted to the current salary for an assistant to the president, $183,000.
The Census Affects Nearly $1 Trillion in Spending
The 2020 census faces possible delay as the Supreme Court sorts out the legality of a controversial citizenship question added by the Trump administration. Tracy Gordon of the Tax Policy Center notes that in addition to the basic issue of political representation, the decennial population count affects roughly $900 billion in federal spending, ranging from Medicaid assistance funds to Section 8 housing vouchers. Here’s a look at the top 10 programs affected by the census:
Chart of the Day: Offshore Profits Continue to Rise
Brad Setser, a former U.S. Treasury economist now with the Council on Foreign Relations, added another detail to his assessment of the foreign provisions of the Tax Cuts and Jobs Act: “A bit more evidence that Trump's tax reform didn't change incentives to offshore profits: the enormous profits that U.S. firms report in low tax jurisdictions continues to rise,” Setser wrote. “In fact, there was a bit of a jump up over the course of 2018.”
