Machine learning and quantum computers – A new revolution

By Muhammad Abdullah Khan 4 years ago

Electrons have a unique spin. Scientists working on quantum computers have been trying to use this characteristic electronic spin of individual electrons in quantum dots to serve as the smallest units to store information. However, the process is massively time-consuming. However, scientists from the University of Oxford, in collaboration with Basel and Lancaster University, have developed an algorithm for machine learning that can be used to measure quantum dots automatically.

Dr. Natalia Ares from the University of Oxford’s Department of Materials said: ‘For the first time, we’ve applied machine learning to perform efficient measurements in gallium arsenide quantum dots, thereby allowing for the characterization of large arrays of quantum devices.’

Scientists have already discovered for many years that the characteristic electronic spin of electrons is the smallest and a perfect candidate for the storage of information. These information units to be used in quantum computers are called “qubit”.

Professor Dr. Dominik Zumbühl from the University of Basel said:  ‘With this work, we’ve made a key contribution that will pave the way for large-scale qubit architectures.’

Quantum dots are tiny semiconductor particles of the size of a few nanometers. Individual electrons, with distinct electronic spin, are trapped inside the quantum dots. With changing voltages inside the trap, the electrons inside the quantum dot can be controlled reliably and their spins can be varied by changing the voltages.

However, this process of tuning the number of electrons, coming into the quantum dots from reservoirs via tunneling effects, and controlling the spins of electrons has to be done very carefully to achieve optimal results. Several quantum dots are used simultaneously in quantum devices, and this tuning process becomes a very time- consuming process.

Now the scientists, by providing data of varying voltages across the quantum dots, for machine learning, have trained the machines to carry out this humongous task.

This breakthrough algorithm for machine learning to fine-tune quantum dots will help to automate the process.

  1. Hi there, i read your blog from time to time and i own a similar one and i was just curious
    if you get a lot of spam feedback? If so how do you protect against
    it, any plugin or anything you can suggest? I get so much lately it’s
    driving me crazy so any help is very much appreciated.

  3. Unquestionably imagine that that you stated. Your favorite
    justification appeared to be on the internet the simplest thing
    to have in mind of. I say to you, I certainly get annoyed even as other people think about worries
    that they just do not realize about. You controlled
    to hit the nail upon the highest as smartly as outlined out the whole thing with no need side effect , folks could take a signal.
    Will probably be back to get more. Thank you

  5. I do not even understand how I stopped up here, however
    I assumed this put up was good. I don’t recognise who you’re however certainly you
    are going to a well-known blogger should you aren’t already.
    Cheers!

  6. Wonderful beat ! I would like to apprentice whilst you amend your web site, how could i subscribe for
    a weblog website? The account helped me a applicable deal.
    I had been a little bit familiar of this your broadcast offered shiny clear idea

  7. An impressive share! I have just forwarded this onto a co-worker who was
    doing a little homework on this. And he in fact bought me dinner due to the fact that I discovered it for him…
    lol. So allow me to reword this…. Thanks for the
    meal!! But yeah, thanx for spending the time to discuss this issue here on your blog.

  8. Hey there! I’ve been following your weblog for a
    while now and finally got the courage to go ahead and give
    you a shout out from Lubbock Texas! Just wanted to mention keep up the excellent job!

  16. With havin so much content do you ever run into any problems of plagorism or copyright violation? My site
    has a lot of unique content I’ve either created myself or outsourced but it looks like a lot of it is popping it
    up all over the internet without my agreement.

    Do you know any methods to help reduce content from being ripped off?
    I’d really appreciate it.

  20. Hi would you mind stating which blog platform you’re working with?

    I’m planning to start my own blog in the near future but I’m having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your layout seems different then most blogs and I’m looking for something completely
    unique. P.S Sorry for getting off-topic but I
    had to ask!
