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.
Marco Rubio Says There’s No Proof Tax Cuts Are Helping American Workers
Sen. Marco Rubio (R-FL) told The Economist that his party’s defense of the massive tax cuts passed last year may be off base: “There is still a lot of thinking on the right that if big corporations are happy, they’re going to take the money they’re saving and reinvest it in American workers,” Rubio said. “In fact they bought back shares, a few gave out bonuses; there’s no evidence whatsoever that the money’s been massively poured back into the American worker.”
For Richer or Poorer: An Updated Marriage Bonus and Penalty Calculator
The Tax Policy Center has updated its Marriage Bonus and Penalty Calculator for 2018, including the new GOP-passed tax law. The tool lets users calculate the difference in income taxes a couple would owe if filing as married or separately. “Most couples will pay lower income taxes after they are married than they would as two separate taxpayers (a marriage bonus), but some will pay a marriage penalty," TPC’s Daniel Berger writes. “Typically, couples with similar incomes will be hit with a penalty while those where one spouse earns significantly more than the other will almost always get a bonus for walking down the aisle.”
Trump Administration Wants to Raise the Rent
Housing and Urban Development Secretary Ben Carson will propose increasing the rent obligation for low-income households receiving federal housing subsidies, as well as creating new work requirements for subsidy recipients. Some details via The Washington Post: “Currently, tenants generally pay 30 percent of their adjusted income toward rent or a public housing agency minimum rent not to exceed $50. The administration’s legislative proposal sets the family monthly rent contribution at 35 percent of gross income or 35 percent of their earnings by working 15 hours a week at the federal minimum wage -- or approximately $150 a month, three times higher than the current minimum.” (The Washington Post)
New Push for Capital Gains Tax Cut
Anti-tax activists in Washington are renewing their pressure on lawmakers to pass new legislation indexing capital gains taxes to inflation. The Hill provided an example of such indexing that Grover Norquist recently sent to Treasury Secretary Steven Mnuchin: “Under current policy, someone who made an investment of $1,000 in 2000 and sold it for $2,000 in 2017 would pay capital gains taxes on the $1,000 difference. But if capital gains were indexed, the investor would only pay taxes on $579, since $1,000 in 2000 would be equivalent to $1,421 in 2017 after adjusting for inflation.” Proponents of indexing say it’s just a matter of fairness, but critics claim that it would be just another regressive tax cut for the wealthy. Indexing would cost an estimated $10 billion a year in lost revenues. (The Hill)
Bernie Sanders to Propose Plan Guaranteeing a Job for Every American
Sen. Bernie Sanders (I-VT) is preparing to announce a plan for the federal government to guarantee a job paying $15 an hour and providing health-care benefits to every American “who wants one or needs one.” The jobs would be on government projects in areas such as infrastructure, care giving, the environment and education. The proposal is still being crafted, and Sanders’ representative said his office had not yet come up with a cost estimate or funding plan. Sen. Kirsten Gillibrand (D-NY) last week tweeted support for a federal jobs guarantee, but Republicans have long opposed such proposals, saying they would cost too much. (Washington Post)
