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.
Tweet of the Day: The Black Hole of Big Pharma
Billionaire John D. Arnold, a former energy trader and hedge fund manager turned philanthropist with a focus on health care, says Big Pharma appears to have a powerful hold on members of Congress.
Arnold pointed out that PhRMA, the main pharmaceutical industry lobbying group, had revenues of $459 million in 2018, and that total lobbying on behalf of the sector probably came to about $1 billion last year. “I guess $1 bil each year is an intractable force in our political system,” he concluded.
Warren’s Taxes Could Add Up to More Than 100%
The Wall Street Journal’s Richard Rubin says Elizabeth Warren’s proposed taxes could claim more than 100% of income for some wealthy investors. Here’s an example Rubin discussed Friday:
“Consider a billionaire with a $1,000 investment who earns a 6% return, or $60, received as a capital gain, dividend or interest. If all of Ms. Warren’s taxes are implemented, he could owe 58.2% of that, or $35 in federal tax. Plus, his entire investment would incur a 6% wealth tax, i.e., at least $60. The result: taxes as high as $95 on income of $60 for a combined tax rate of 158%.”
In Rubin’s back-of-the-envelope analysis, an investor worth $2 billion would need to achieve a return of more than 10% in order to see any net gain after taxes. Rubin notes that actual tax bills would likely vary considerably depending on things like location, rates of return, and as-yet-undefined policy details. But tax rates exceeding 100% would not be unusual, especially for billionaires.
Biden Proposes $1.3 Trillion Infrastructure Plan
Joe Biden on Thursday put out a $1.3 trillion infrastructure proposal. The 10-year “Plan to Invest in Middle Class Competitiveness” calls for investments to revitalize the nation’s roads, highways and bridges, speed the adoption of electric vehicles, launch a “second great railroad revolution” and make U.S. airports the best in the world.
“The infrastructure plan Joe Biden released Thursday morning is heavy on high-speed rail, transit, biking and other items that Barack Obama championed during his presidency — along with a complete lack of specifics on how he plans to pay for it all,” Politico’s Tanya Snyder wrote. Biden’s campaign site says that every cent of the $1.3 trillion would be paid for by reversing the 2017 corporate tax cuts, closing tax loopholes, cracking down on tax evasion and ending fossil-fuel subsidies.

Number of the Day: 18 Million
There were 18 million military veterans in the United States in 2018, according to the Census Bureau. That figure includes 485,000 World War II vets, 1.3 million who served in the Korean War, 6.4 million from the Vietnam War era, 3.8 million from the first Gulf War and another 3.8 million since 9/11. We join with the rest of the country today in thanking them for their service.
Chart of the Day: Dem Candidates Face Their Own Tax Plans
Democratic presidential candidates are proposing a variety of new taxes to pay for their preferred social programs. Bloomberg’s Laura Davison and Misyrlena Egkolfopoulou took a look at how the top four candidates would fare under their own tax proposals.
