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.
Coming Soon: Deductible Relief Day!
You may be familiar with the concept of Tax Freedom Day – the date on which you have earned enough to pay all of your taxes for the year. Focusing on a different kind of financial burden, analysts at the Kaiser Family Foundation have created Deductible Relief Day – the date on which people in employer-sponsored insurance plans have spent enough on health care to meet the average annual deductible.
Average deductibles have more than tripled over the last decade, forcing people to spend more out of pocket each year. As a result, Deductible Relief Day is “getting later and later in the year,” Kaiser’s Larry Levitt said in a tweet Thursday.
Chart of the Day: Families Still Struggling
Ten years into what will soon be the longest economic expansion in U.S. history, 40% of families say they are still struggling, according to a new report from the Urban Institute. “Nearly 4 in 10 nonelderly adults reported that in 2018, their families experienced material hardship—defined as trouble paying or being unable to pay for housing, utilities, food, or medical care at some point during the year—which was not significantly different from the share reporting these difficulties for the previous year,” the report says. “Among adults in families with incomes below twice the federal poverty level (FPL), over 60 percent reported at least one type of material hardship in 2018.”
Chart of the Day: Pragmatism on a Public Option
A recent Morning Consult poll 3,073 U.S. adults who say they support Medicare for All shows that they are just as likely to back a public option that would allow Americans to buy into Medicare or Medicaid without eliminating private health insurance. “The data suggests that, in spite of the fervor for expanding health coverage, a majority of Medicare for All supporters, like all Americans, are leaning into their pragmatism in response to the current political climate — one which has left many skeptical that Capitol Hill can jolt into action on an ambitious proposal like Medicare for All quickly enough to wrangle the soaring costs of health care,” Morning Consult said.
Chart of the Day: The Explosive Growth of the EITC
The Earned Income Tax Credit, a refundable tax credit for low- to moderate-income workers, was established in 1975, with nominal claims of about $1.2 billion ($5.6 billion in 2016 dollars) in its first year. According to the Tax Policy Center, by 2016 “the total was $66.7 billion, almost 12 times larger in real terms.”
Chart of the Day: The Big Picture on Health Care Costs
“The health care services that rack up the highest out-of-pocket costs for patients aren't the same ones that cost the most to the health care system overall,” says Axios’s Caitlin Owens. That may distort our view of how the system works and how best to fix it. For example, Americans spend more out-of-pocket on dental services ($53 billion) than they do on hospital care ($34 billion), but the latter is a much larger part of national health care spending as a whole.
