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.
Number of the Day: $132,900
The cap on Social Security payroll taxes will rise to $132,900 next year, an increase of 3.5 percent. (Earnings up to that level are subject to the Social Security tax.) The increase will affect about 11.6 million workers, Politico reports. Beneficiaries are also getting a boost, with a 2.8 percent cost-of-living increase coming in 2019.
Photo of the Day: Kanye West at the White House
This is 2018: Kanye West visited President Trump at the White House Thursday and made a rambling 10-minute statement that aired on TV news networks. West’s lunch with the president was supposed to focus on clemency, crime in his hometown of Chicago and economic investment in urban areas, but his Oval Office rant veered into the bizarre. And since this is the world we live in, we’ll also point out that West apparently became “the first person to ever publicly say 'mother-f***er' in the Oval Office.”
Trump called Kanye’s monologue “pretty impressive.”
“That was bonkers,” MSNBC’s Ali Velshi said afterward.
Again, this is 2018.
Chart of the Day: GDP Growth Before and After the Tax Bill
President Trump and the rest of the GOP are celebrating the recent burst in economic growth in the wake of the tax cuts, with the president claiming that it’s unprecedented and defies what the experts were predicting just a year ago. But Rex Nutting of MarketWatch points out that elevated growth rates over a few quarters have been seen plenty of times in recent years, and the extra growth generated by the Republican tax cuts was predicted by most economists, including those at the Congressional Budget Office, whose revised projections are shown below.
Are States Ready for the Next Downturn?
The Great Recession hit state budgets hard, but nearly half are now prepared to weather the next modest downturn. Moody’s Analytics says that 23 states have enough reserves to meet budget shortfalls in a moderate economic contraction, up from just 16 last year, Bloomberg reports. Another 10 states are close. The map below shows which states are within 1 percent of their funding needs for their rainy day funds (in green) and which states are falling short.
Chart of the Day: Evolving Price of the F-35
The 2019 National Defense Authorization Act signed in August included 77 F-35 Lightning II jets for the Defense Department, but Congress decided to bump up that number in the defense spending bill finalized this week, for a total of 93 in the next fiscal year – 16 more than requested by the Pentagon. Here’s a look from Forbes at the evolving per unit cost of the stealth jet, which is expected to eventually fall to roughly $80 million when full-rate production begins in the next few years.
