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.

Despite the Republican tax overhaul, businesses aren’t significantly increasing their capital expenditures. “The federal government will have to borrow an added $1 trillion through 2027 to pay for the corporate tax breaks,” says Bloomberg’s Mark Whitehouse. “So far, it’s hard to see what the country is getting in return.”

Can You Fix Social Security? A New Tool Lets You Try
The Congressional Budget Office released an interactive tool Wednesday that shows how some widely discussed policy changes would affect the long-run financial health of the Social Security system.
“This interactive tool allows the user to explore seven policy options that could be used to improve the Social Security program’s finances and delay the trust funds’ exhaustion,” CBO said. “Four options would reduce benefits, and three options would increase payroll taxes. The tool allows for any combination of those options. It also lets the user change implementation dates and choose whether to show scheduled or payable benefits. … The tool also shows the impact of the options on different groups of people.”

Why Prescription Drug Prices Keep Rising – and 3 Ways to Bring Them Down
Prescription drug prices have been rising at a blistering rate over the last few decades. Between 1980 and 2016, overall spending on prescription drugs rose from about $12 billion to roughly $330 billion, while its share of total health care spending doubled, from 5% to 10%.
Although lawmakers have shown renewed interest in addressing the problem, with pharmaceutical CEOs testifying before the Senate Finance Committee in February and pharmacy benefit managers (PBMS) scheduled to do so this week, no comprehensive plan to halt the relentless increase in prices has been proposed, let alone agreed upon.
Robin Feldman, a professor at the University of California Hastings College of Law, takes a look at the drug pricing system in a new book, “Drugs, Money and Secret Handshakes: The Unstoppable Growth of Prescription Drug Prices.” In a recent conversation with Bloomberg’s Joe Nocera, Feldman said that one of the key drivers of rising prices is the ongoing effort of pharmaceutical companies to maintain control of the market.
Fearing competition from lower-cost generics, drugmakers began over the last 10 or 15 years to focus on innovations “outside of the lab,” Feldman said. These innovations include paying PBMs to reduce competition from generics; creating complex systems of rebates to PBMs, hospitals and doctors to maintain high prices; and gaming the patent system to extend monopoly pricing power.
Feldman’s research on the dynamics of the drug market led her to formulate three general solutions for the problem of ever-rising prices:
1) Transparency: The current system thrives on secret deals between drug companies and middlemen. Transparency “lets competitors figure out how to compete and it lets regulators see where the bad behaviors occur,” Feldman says.
2) Patent limitations: Drugmakers have become experts at extending patents on existing drugs, often by making minor modifications in formulation, dosage or delivery. Feldman says that 78% of drugs getting new patents are actually old drugs gaining another round of protection, and thus another round of production and pricing exclusivity. A “one-and-done” patent system would eliminate this increasingly common strategy.
3) Simplification: Feldman says that “complexity breeds opportunity,” and warns that the U.S. “drug price system is so complex that the gaming opportunities are endless.” While “ruthless simplification” of regulatory rules and approval systems could help eliminate some of those opportunities, Feldman says that the U.S. doesn’t seem to be moving in this direction.
