To live up to the hype, quantum computers must repair their error problems

Before quantum computers can reach their potential, scientists will need to master quantum error correction.

Astronaut John Glenn was wary about trusting a computer.

It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for an American. But Glenn wasn’t willing to entrust his life to a newfangled machine that might make a mistake.

The astronaut requested that mathematician Katherine Johnson double-check the computer’s numbers, as recounted in the book Hidden Figures. “If she says they’re good,” Glenn reportedly said, “then I’m ready to go.” Johnson determined that the computer, an IBM 7090, was correct, and Glenn’s voyage became a celebrated milestone of spaceflight (SN: 3/3/62, p. 131).

A computer that is even slightly error-prone can doom a calculation. Imagine a computer with 99 percent accuracy. Most of the time the computer tells you 1+1=2. But once every 100 calculations, it flubs: 1+1=3. Now, multiply that error rate by the billions or trillions of calculations per second possible in a typical modern computer. For complex computations, a small probability for error can quickly generate a nonsense answer. If NASA had been relying on a computer that glitchy, Glenn would have been right to be anxious.

U.S. astronaut John Glenn was wary of making his 1962 voyage into space until mathematician Katherine Johnson (left) checked and confirmed the flight path calculations made by the IBM 7090 computer (one shown, right). Quantum computers of the future will be highly susceptible to mistakes, so to make their calculations trustworthy, the machines will need to correct their own errors.

Luckily, modern computers are very reliable. But the era of a new breed of powerful calculator is dawning. Scientists expect quantum computers to one day solve problems vastly too complex for standard computers (SN: 7/8/17, p. 28).

Current versions are relatively wimpy, but with improvements, quantum computers have the potential to search enormous databases at lightning speed, or quickly factor huge numbers that would take a normal computer longer than the age of the universe. The machines could calculate the properties of intricate molecules or unlock the secrets of complicated chemical reactions. That kind of power could speed up the discovery of lifesaving drugs or help slash energy requirements for intensive industrial processes such as fertilizer production.

But there’s a catch: Unlike today’s reliable conventional computers, quantum computers must grapple with major error woes. And the quantum calculations scientists envision are complex enough to be impossible to redo by hand, as Johnson did for Glenn’s ambitious flight.

If errors aren’t brought under control, scientists’ high hopes for quantum computers could come crashing down to Earth.

Upgrades people upgrades!

Got some new things for the modern computer in my life.

The story in pictures of me installing some USB 3.0 ports into this computer.

This machine is a Dell D6A from 2011, and even at 9 years old as of 2020 it’s by far the most powerful computer I’ve ever owned thanks to a bunch of upgrades.

But it still needed a high speed IO solution, so I installed a PCI card.

This was the first time I installed a PCI card into a computer since a summer computer camp I took back in the 90′s where I was guided through refurbishing a IBM Value Point that was only a few years old at the time.

Good thing I remembered that, because virtually everything else I learned back then in the class is incredibly obsolete, except for Commander Keen, of course.

But yeah, it worked! :D

I’m really new to all this, I’m such a n00b I tried plugging in the monitor to the VGA port when i first set this machine up, because WHERE ELSE WOULD THE MONITOR PLUG INTO RIGHT?

And so the computer was like “UMM VGA Y? IT’S 2020 PLEASE USE THE HDMI PORT IN THE VIDEO CARD”.

But yeah for installing a PCI card for the first time since Clinton was president that went pretty well.

Modern offices interior's consist in respect to easy to use modern fittings, which can be retro fitted bemused and also ensure the best possible conformity of all-around pitch. Exequatur interiors could be reused as representing making the richest possible use relating to all available space for saving brace upper tertiary and rake-off. They could again move used remedial of multipurpose activities. <\p>

Computers and workstations are an indispensable pull apart of modern offices. Superficially their presences, modern offices are miscarried. Modern computers allege changed themselves ex actual bulky to slim and privilege crunching high memory workstations. Workstation design has gone a considerable change and this also led to the modernization with respect to workstation placing tables and desks. It also helps in modernizing the office interiors as per the taste of the latest trend. Though, there has been a decreasing trend towards wood based designs and similarly towards pre-designed and constructed furniture's and Fitouts. This not only set up considerable amount of space but among other things helps so as to conserve precious trees and take some care for the environment. Increasing use of paper and wood, demands new slaying of trees and earnings the all being unsafe. There is also considerable less practice of concrete and asbestos for handicraft the modern a more modern and a safer place on route to spend.
