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.
Chart of the Day: Boosting Corporate Tax Revenues
The leading candidates for the Democratic presidential nomination have all proposed increasing taxes on corporations, including raising income tax rates to levels ranging from 25% to 35%, up from the current 21% imposed by the Republican tax cuts in 2017. With Bernie Sanders leading the way at $3.9 trillion, here’s how much revenue the higher proposed corporate taxes, along with additional proposed surtaxes and reduced tax breaks, would generate over a decade, according to calculations by the right-leaning Tax Foundation, highlighted Wednesday by Bloomberg News.
Chart of the Day: Discretionary Spending Droops
The federal government’s total non-defense discretionary spending – which covers everything from education and national parks to veterans’ medical care and low-income housing assistance – equals 3.2% of GDP in 2020, near historic lows going back to 1962, according to an analysis this week from the Center on Budget and Policy Priorities.
Chart of the Week: Trump Adds $4.7 Trillion in Debt
The Committee for a Responsible Federal Budget estimated this week that President Trump has now signed legislation that will add a total of $4.7 trillion to the national debt between 2017 and 2029. Tax cuts and spending increases account for similar portions of the projected increase, though if the individual tax cuts in the 2017 Republican overhaul are extended beyond their current expiration date at the end of 2025, they would add another $1 trillion in debt through 2029.
Chart of the Day: The Long Decline in Interest Rates
Are interest rates destined to move higher, increasing the cost of private and public debt? While many experts believe that higher rates are all but inevitable, historian Paul Schmelzing argues that today’s low-interest environment is consistent with a long-term trend stretching back 600 years.
The chart “shows a clear historical downtrend, with rates falling about 1% every 60 years to near zero today,” says Bloomberg’s Aaron Brown. “Rates do tend to revert to a mean, but that mean seems to be declining.”
Chart of the Day: Drug Price Plans Compared
Lawmakers are considering three separate bills that are intended to reduce the cost of prescription drugs. Here’s an overview of the proposals, from a series of charts produced by the Kaiser Family Foundation this week. An interesting detail highlighted in another chart: 88% of voters – including 92% of Democrats and 85% of Republicans – want to give the government the power to negotiate prices with drug companies.
