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.
Quote of the Day: The Health Care Revolution That Wasn’t
“The fact is very little medical care is shoppable. We become good shoppers when we are repeat shoppers. If you buy a new car every three years, you can become an informed shopper. There is no way to become an informed shopper for your appendix. You only get your appendix out once.”
— David Newman, former director of the Health Care Cost Institute, quoted in an article Thursday by Noam Levey of the Los Angeles Times. Levey says the “consumer revolution” in health care – in which patients shop around for the best prices, forcing doctors, hospitals and pharmaceutical firms to compete with lower prices – hasn’t materialized, but the higher deductibles that were part of the effort are very much in effect. “High-deductible health insurance was supposed to make American patients into smart shoppers,” Levey writes. “Instead, they got stuck with medical bills they can't afford.”
Congressional Report of the Day: The US Pays Nearly 4 Times More for Drugs
The House Ways and Means Committee released a new analysis of drug prices in the U.S. compared to 11 other developed nations, and the results, though predictable, aren’t pretty. Here are the key findings from the report:
- The U.S. pays the most for drugs, though prices varied widely.
- U.S. drug prices were nearly four times higher than average prices compared to similar countries.
- U.S. consumers pay significantly more for drugs than other countries, even when accounting for rebates.
- The U.S. could save $49 billion annually on Medicare Part D alone by using average drug prices for comparator countries.

Chart of the Day: How the US Ranks for Retirement
The U.S. ranks 18th for retiree well-being among developed nations, according to the latest Global Retirement Index from Natixis, the French corporate and investment bank. The U.S. fell two spots in the ranking this year, due in part to rising economic inequality and poor performance for life expectancy.
About 90% of Trump Counties Have Received Trade War Farm Aid
President Trump won more than 2,600 of the nation’s 3,000-plus counties in the 2016 election, and residents in nearly 90% of those counties – or more than 2,300 – have received some level of aid from the administration’s Market Facilitation Program, a $16 billion effort that compensates farmers for losses incurred as a result of Trump’s trade war with China.
Drawing on a new report from the Environmental Working Group, The Washington Post’s Philip Bump says the data “show the extent to which [the farm] subsidies overlap with Trump’s base of political support.”
To be fair, about 80% of the counties Hillary Clinton won also received some degree of aid, Bump says, but there are many fewer of them, given the concentration of her supporters in urban areas.
Overall, residents in more than 2,600 counties in the U.S. have received payments from the farm aid program, with the heaviest concentration in the Midwest.
Number of the Day: $1.57
A new study from the Bipartisan Policy Center says that Medicare would save $1.57 for every dollar it spends delivering healthy food to elderly beneficiaries who have recently been discharged from the hospital. The savings would come from a reduction in the rate of readmissions to the hospital for patients suffering from a wide range of common ailments, including rheumatoid arthritis, congestive heart failure, diabetes and emphysema.
“If you were going to offer meals to every Medicare beneficiary, it would be cost-prohibitive,” said BPC’s Katherine Hayes. “By targeting it to a very, very sick group of people is how we were able to show there could be savings.”
