Quantum computers could one day blow boring old classical computers out of the water, but so far their complexity limits their usefulness. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single atom is entangled with a series of photons to process and store information.
Quantum computers tap into the weird world of quantum physics to perform calculations far faster than traditional computers can handle. Where existing machines store and process information in bits, as either ones and zeroes, quantum computers use qubits, which can exist as one, zero, or a superposition of both one and zero at the same time. That means their power scales exponentially with each added qubit, allowing them to tackle problems beyond the reach of classical computers.
Of course, quantum computers bring their own challenges. For one, the quantum effects they run on are sensitive to disturbances like vibration or heat, so quantum computers need to be kept at temperatures approaching absolute zero. As such, their complexity scales with the computing power of the machine, so they become physically larger and more cumbersome as more processing power is added.
But the Stanford team says their new design is deceptively simple. It’s a photonic circuit made using a few components that are already available – a fiber optic cable, a beam splitter, two optical switches and an optical cavity – and it can reduce the number of physical logic gates needed.
“Normally, if you wanted to build this type of quantum computer, you’d have to take potentially thousands of quantum emitters, make them all perfectly indistinguishable, and then integrate them into a giant photonic circuit,” says Ben Bartlett, lead author of the study. “Whereas with this design, we only need a handful of relatively simple components,

Moore’s Law just got a reprieve.................
You can run the computer off of the Tesla.
SHHHHH! Don’t tell the Chinese!
Can it run lotus notes adequately?
Horrid software.
Scientists Are One Step Closer To Error-Correcting Quantum Computers
Now I see that I was using the wrong brand of seasoning.
Thanks!
I kind of want my IBM 1130 back.
Wargames, here we come:
Yeah!
Now, where do we get off-the-shelf cryogenic system that yields 0.002 degrees Kelvin?
I’ll check Lowes or Amazon to price one out...
That’s obviously fake. easily dismissed because there’s no hamster in the exercise cage. How else could it run?
It’s quantum. You looked in the cage and killed the Schrodinger’s hamster.
I was going to try to cool mine by playing recordings of democrat's very cold statements such as "Let them learn to code" and "Old people have a duty to die and get out of the way" and "What difference does it make?"
If that doesn't work then I'll try the 6 degrees of Kelvin Bacon approach.
This article actually says that it would run at around room temperature.
The author has obviously not seen my shelf. Ain’t happening.
Now, where do we get off-the-shelf cryogenic system that yields 0.002 degrees Kelvin?
+++++
Read the full article. This machine works at ROOM TEMPERATURE.
For me, that is the real news. I’ve worked with Liquid Nitrogen + Liquid Helium cryogenic systems in the past and you are correct in pointing out that they will never be anything but scientific tools.
So this may really be big news.
