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.
Chart of the Day: A Buying Binge Driven by Tax Cuts
The Wall Street Journal reports that the tax cuts and economic environment are prompting U.S. companies to go on a buying binge: “Mergers and acquisitions announced by U.S. acquirers so far in 2018 are running at the highest dollar volume since the first two months of 2000, according to Dealogic. Thomson Reuters, which publishes slightly different numbers, puts it at the highest since the start of 2007.”
Number of the Day: 5.5 Percent
Health care spending in the U.S. will grow at an average annual rate of 5.5 percent from 2017 through 2026, according to new estimates published in Health Affairs by the Office of the Actuary at the Centers for Medicare and Medicaid Services (CMS).
The projections mean that health care spending would rise as a share of the economy from 17.9 percent in 2016 to 19.7 percent in 2026.
Trump Clearly Has No Problem with Debt and Deficits
A self-proclaimed “king of debt,” President Trump has produced a budget that promises red ink as far as the eye can see. With last year's $1.5 trillion tax cut reducing revenues, the White House gave up even trying to pretend that its budget would balance anytime soon, and even the rosy economic projections contained in the budget couldn’t produce enough revenues, however fanciful, to cover the shortfall.
The Trump budget spends as much over 10 years as any budget produced by President Barack Obama, according to Jim Tankersley of The New York Times. And it projects total deficits of more than $7 trillion over the next decade — "a number that could double if the administration turns out to be overestimating economic growth and if the $3 trillion in spending cuts the White House has floated do not materialize in Congress,” Tankersley says.
Trump — who once promised to both balance the budget and pay down the national debt — isn’t the only one throwing off the shackles of fiscal restraint. Republicans as a whole appear to be embracing a new set of economic preferences defined by lower taxes and higher spending, in what Bloomberg describes as a “striking turnabout” in attitudes toward deficits and the national debt.
But some conservatives tell Tankersley that the GOP's core beliefs on spending and debt remain intact — and that spending on Social Security and Medicare, the primary drivers of the national debt, are all that matters when it comes to implementing fiscal restraint.
“They know that right now, a fundamental reform of entitlements won’t happen," John H. Cochrane, an economist at Stanford University’s Hoover Institution, tells Tankersley. "So, they have avoided weekly chaos and gotten needed military spending through by opening the spending bill, and they got an important reduction in growth-distorting marginal corporate rates through by accepting a bit more deficits. They know that can’t be the end of the story.”
Democrats, of course, have warned that the next chapter in the tale will involve big cuts to Social Security and Medicare. Even before we get there, though, Tankersley questions whether the GOP approach stands up to scrutiny: "This is a bit like saying, only regular exercise will keep America from having a fatal heart attack, so, you know, it's ok to eat a few more hamburgers now."
Part of the Shutdown-Ending Deal: $31 Billion More in Tax Cuts
Margot Sanger-Katz and Jim Tankersley in The New York Times: “The deal struck by Democrats and Republicans on Monday to end a brief government shutdown contains $31 billion in tax cuts, including a temporary delay in implementing three health care-related taxes.”
“Those delays, which enjoy varying degrees of bipartisan support, are not offset by any spending cuts or tax increases, and thus will add to a federal budget deficit that is already projected to increase rapidly as last year’s mammoth new tax law takes effect.”
IRS Paid $20 Million to Collect $6.7 Million in Tax Debts
Congress passed a law in 2015 requiring the IRS to use private debt collection agencies to pursue “inactive tax receivables,” but the financial results are not encouraging so far, according to a new taxpayer advocate report out Wednesday.
In fiscal year 2017, the IRS received $6.7 million from taxpayers whose debts were assigned to private collection agencies, but the agencies were paid $20 million – “three times the amount collected,” the report helpfully points out.
