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.
Why Craft Brewers Are Crying in Their Beer
It may be small beer compared to the problems faced by unemployed federal workers and the growing cost for the overall economy, but the ongoing government shutdown is putting a serious crimp in the craft brewing industry. Small-batch brewers tend to produce new products on a regular basis, The Wall Street Journal’s Ruth Simon says, but each new formulation and product label needs to be approved by the Treasury Department’s Alcohol and Tobacco Tax and Trade Bureau, which is currently closed. So it looks like you’ll have to wait a while to try the new version of Hemperor HPA from Colorado’s New Belgium Brewing, a hoppy brew that will include hemp seeds once the shutdown is over.
Number of the Day: $30 Billion
The amount spent on medical marketing reached $30 billion in 2016, up from $18 billion in 1997, according to a new analysis published in the Journal of the American Medical Association and highlighted by the Associated Press. The number of advertisements for prescription drugs appearing on television, newspapers, websites and elsewhere totaled 5 million in one year, accounting for $6 billion in marketing spending. Direct-to-consumer marketing grew the fastest, rising from $2 billion, or 12 percent of total marketing, to nearly $10 billion, or a third of spending. “Marketing drives more treatments, more testing” that patients don’t always need, Dr. Steven Woloshin, a Dartmouth College health policy expert and co-author of the study, told the AP.
70% of Registered Voters Want a Compromise to End the Shutdown
An overwhelming majority of registered voters say they want the president and Congress to “compromise to avoid prolonging the government shutdown” in a new The Hill-HarrisX poll. Seven in ten respondents said they preferred the parties reach some sort of deal to end the standoff, while 30 percent said it was more important to stick to principles, even if it means keeping parts of the government shutdown. Voters who “strongly approve” of Trump (a slim 21 percent of respondents) favored him sticking to his principles over the wall by a narrow 54 percent-46 percent margin. Voters who “somewhat approve” of the president favored a compromise solution by a 70-30 margin. Among Republicans overall, 61 percent said they wanted a compromise.
The survey of 1,000 registered voters was conducted January 5 and 6 and has a margin of error of 3.1 percentage points.
Share Buybacks Soar to Record $1 Trillion
Although there may be plenty of things in the GOP tax bill to complain about, critics can’t say it didn’t work – at least as far as stock buybacks go. TrimTabs Investment Research said Monday that U.S. companies have now announced $1 trillion in share buybacks in 2018, surpassing the record of $781 billion set in 2015. "It's no coincidence," said TrimTabs' David Santschi. "A lot of the buybacks are because of the tax law. Companies have more cash to pump up the stock price."
Chart of the Day: Deficits Rising
Budget deficits normally rise during recessions and fall when the economy is growing, but that’s not the case today. Deficits are rising sharply despite robust economic growth, increasing from $666 billion in 2017 to an estimated $970 billion in 2019, with $1 trillion annual deficits expected for years after that.
As the deficit hawks at the Committee for a Responsible Federal Budget point out in a blog post Thursday, “the deficit has never been this high when the economy was this strong … And never in modern U.S. history have deficits been so high outside of a war or recession (or their aftermath).” The chart above shows just how unusual the current deficit path is when measured as a percentage of GDP.
