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.
Can Trump Bring Democrats Along on Taxes?
Although Republicans are prepared to go it alone on tax reform, President Trump suggested creating a bipartisan working group on the topic during a Wednesday meeting with senators from both parties. Some senators were open to the idea, but it doesn’t look like Republicans have much interest in slowing down the process with in-depth negotiations. “I don’t really personally see the benefit of creating additional structure. I think we’ve got all the tools we need,” said Sen. John Cornyn (R-TX), who attended the meeting, according to Politico. Democrats appear skeptical, too. Sen. Ron Wyden (D-OR) said he told Trump that the distance between what Republicans were saying about their plan and what it actually does is a serious problem.
Where Trump Will Compromise on Tax Reform
White House officials tell USA Today’s Heidi Przybyla that President Trump will include a number of compromises to limit his tax plan’s benefits for the wealthy when he promotes the blueprint next month:
“The compromises will include ending a 23.8% preferential tax rate for hedge-fund managers, or the so-called carried interest rate, White House legislative affairs director Marc Short told USA TODAY. … Retaining parts of a state and local tax deduction that benefits many middle-class families in blue states is also an area where Trump is expecting compromise.”
Trump campaigned on raising the carried interest rate, saying its beneficiaries are “getting away with murder.” But changes to the carried interest rate may run into opposition from House Republicans, and the tweaks appear unlikely to win any Democratic support.
Larry Summers Savages Trump Tax Plan Analysis
Former Treasury Secretary Larry Summers made his distaste for the Trump administration’s tax framework clear last week when he said Republicans were using “made-up” claims about the plan and its effects. Summers expanded his criticism on Tuesday in a blog post that took aim at the report released Monday by the Council of Economic Advisers and chair Kevin Hassett, which seeks to justify the administration’s claim that its tax plan will result in a $4,000 pay raise for the average American family.
Never one to mince words, Summers says the CEA analysis is “some combination of dishonest, incompetent and absurd.” The pay raise figure is indefensible, since “there is no peer-reviewed support for his central claim that cutting the corporate tax rate from 35 to 20 percent would raise wages by $4000 per worker.” In the end, Summers says that “if a Ph.D student submitted the CEA analysis as a term paper in public finance, I would be hard pressed to give it a passing grade.”
One of the authors cited in the CEA paper also has some concerns. Harvard Business School professor Mihir Desai tweeted Tuesday that the CEA analysis “misinterprets” a 2007 paper he co-wrote on the dynamics of the corporate tax burden. Desai’s research has found a connection between business tax cuts and wage growth, but not as large as the CEA paper claims. “Cutting corporate taxes will help wages but exaggeration only serves to undercut the reasonableness of the core argument,” Desai wrote.
For Tax Reform, It May Be 2017 or Bust
National Economic Council Director Gary Cohn said Monday that tax reform has to happen this year, even if it means Congress has to stay in session longer. "I think we have a unique window in time right now, but unfortunately we keep losing days to this window,” he said. “The opportunity is now." House Speaker Paul Ryan said last week he’d keep members over Christmas if that’s what it takes. And Ryan predicted Monday that tax reform would pass the House by early next month and then get through the Senate to reach the president’s desk by the end of the year. But there are plenty of skeptics out there, given the hurdles. Issac Boltansky, an analyst at the investment bank Compass Point, told Business Insider, "The idea of getting tax reform done this year is a farcical fantasy. Lawmakers have neither the time nor the capacity to formulate and clear a tax reform package in 2017."
Do Republicans Have the Votes for the Next Step Toward Tax Reform?
Passing a budget resolution for 2018 through the Senate will open a procedural door to a $1.5 trillion tax cut over 10 years. The resolution is expected to reach the Senate floor this week, although there are questions about whether Republicans have the 50 votes they need to pass it. Sens. Susan Collins (R-ME) said this weekend that she would vote for it and Lisa Murkowski (R-AK) is likely a “yes” as well, but Sen. Rand Paul (R-TN) is reportedly a likely “no” and John McCain (R-AZ) appears questionable. Now it looks like Sen. Thad Cochran (R-MI) won't be back in Washington this week to vote on the resolution due to health problems. The Hill says Cochran’s absence puts tax reform “on knife’s edge.”
