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.
4.2 Million Uninsured People Could Get Free Obamacare Plans
About 4.2 million uninsured people could sign up for a bronze-level Obamacare health plan and pay nothing for it after tax credits are applied, the Kaiser Family Foundation said Tuesday. That means that 27 percent of the country’s 15.9 million uninsured people could get covered for free. The chart below breaks down the eligible population by state.
Takedown of the Day: Ezra Klein on Paul Ryan's Legacy of Debt
Vox’s Ezra Klein says that retiring House Speaker Paul Ryan’s legacy can be summed up in one number: $343 billion. “That’s the increase between the deficit for fiscal year 2015 and fiscal year 2018— that is, the difference between the fiscal year before Ryan became speaker of the House and the fiscal year in which he retired.”
Klein writes that Ryan’s choices while in office — especially the 2017 tax cuts and the $1.3 trillion spending bill he helped pass and the expansion of the earned income tax credit he talked up but never acted on — should be what define his legacy:
“[N]ow, as Ryan prepares to leave Congress, it is clear that his critics were correct and a credulous Washington press corps — including me — that took him at his word was wrong. In the trillions of long-term debt he racked up as speaker, in the anti-poverty proposals he promised but never passed, and in the many lies he told to sell unpopular policies, Ryan proved as much a practitioner of post-truth politics as Donald Trump. …
“Ultimately, Ryan put himself forward as a test of a simple, but important, proposition: Is fiscal responsibility something Republicans believe in or something they simply weaponize against Democrats to win back power so they can pass tax cuts and defense spending? Over the past three years, he provided a clear answer. That is his legacy, and it will haunt his successors.”
Number of the Day: $300 Million
Mick Mulvaney, the acting director of the Consumer Financial Protection Bureau, wants the agency to be known as the Bureau of Consumer Financial Protection, the name under which it was established by Title X of the 2010 Dodd-Frank Wall Street reform law. Mulvaney even had new signage put up in the lobby of the bureau. But the rebranding could cost the banks and other financial businesses regulated by the bureau more than $300 million, according to an internal agency analysis reported by The Hill’s Sylvan Lane. The costs would arise from having to update internal databases, regulatory filings and disclosure forms with the new name. The rebranding would cost the agency itself between $9 million and $19 million, the analysis estimated. Lane adds that it’s not clear whether Kathy Kraninger, President Trump’s nominee to serve as the bureau’s full-time director, would follow through on Mulvaney’s name change once she is confirmed by the Senate.
Why Trump's Tariffs Are Just a Drop in the Bucket
President Trump said this week that tariff increases by his administration are producing "billions of dollars" in revenues, thereby improving the country’s fiscal situation. But CNBC’s John Schoen points out that while tariff revenues are indeed higher by several billion dollars this year, the total revenue is a drop in the bucket compared to the sheer size of government outlays and receipts – and the growing annual deficit.
Bank Profits Hit New Record Thanks to 2017 Tax Law
Bank profits reached a record $62 billion in the third quarter, up $14 billion, or 29.3 percent, from the same period last year, according to data from the Federal Deposit Insurance Corporation. The FDIC said that about half of the increase in net income was attributable to last year’s tax cuts. The FDIC estimated that, with the effective tax rates from before the new law, bank profits for the quarter would have risen by about 14 percent, to $54.6 billion.
