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.
Tax Refunds Rebound
Smaller refunds in the first few weeks of the current tax season were shaping up to be a political problem for Republicans, but new data from the IRS shows that the value of refund checks has snapped back and is now running 1.3 percent higher than last year. The average refund through February 23 last year was $3,103, while the average refund through February 22 of 2019 was $3,143 – a difference of $40. The chart below from J.P. Morgan shows how refunds performed over the last 3 years.
Number of the Day: $22 Trillion
The total national debt surpassed $22 trillion on Monday. Total public debt outstanding reached $22,012,840,891,685.32, to be exact. That figure is up by more than $1.3 trillion over the past 12 months and by more than $2 trillion since President Trump took office.
Chart of the Week: The Soaring Cost of Insulin
The cost of insulin used to treat Type 1 diabetes nearly doubled between 2012 and 2016, according to an analysis released this week by the Health Care Cost Institute. Researchers found that the average point-of-sale price increased “from $7.80 a day in 2012 to $15 a day in 2016 for someone using an average amount of insulin (60 units per day).” Annual spending per person on insulin rose from $2,864 to $5,705 over the five-year period. And by 2016, insulin costs accounted for nearly a third of all heath care spending for those with Type 1 diabetes (see the chart below), which rose from $12,467 in 2012 to $18,494.
Chart of the Day: Shutdown Hits Like a Hurricane
The partial government shutdown has hit the economy like a hurricane – and not just metaphorically. Analysts at the Committee for a Responsible Federal Budget said Tuesday that the shutdown has now cost the economy about $26 billion, close to the average cost of $27 billion per hurricane calculated by the Congressional Budget Office for storms striking the U.S. between 2000 and 2015. From an economic point of view, it’s basically “a self-imposed natural disaster,” CRFB said.
Chart of the Week: Lowering Medicare Drug Prices
The U.S. could save billions of dollars a year if Medicare were empowered to negotiate drug prices directly with pharmaceutical companies, according to a paper published by JAMA Internal Medicine earlier this week. Researchers compared the prices of the top 50 oral drugs in Medicare Part D to the prices for the same drugs at the Department of Veterans Affairs, which negotiates its own prices and uses a national formulary. They found that Medicare’s total spending was much higher than it would have been with VA pricing.
In 2016, for example, Medicare Part D spent $32.5 billion on the top 50 drugs but would have spent $18 billion if VA prices were in effect – or roughly 45 percent less. And the savings would likely be larger still, Axios’s Bob Herman said, since the study did not consider high-cost injectable drugs such as insulin.
