Quantum mechanics suggest that seemingly empty space is actually filled with ghostly particles that are fluctuating in and out of existence. And now, scientists have for the first time made an advanced machine known as a quantum computer simulate these so-called virtual particles.
With quantum mechanics, scientists always find new and unexplainable things, and when you get to the smallest parts of quantum mechanics, that's when the confusion begins.For instance, atoms and other particles can exist in states of flux known as superpositions, where they can seemingly each spin in opposite directions simultaneously, and they can also get entangled — meaning they can influence each other instantaneously no matter how far apart they are separated.
Scientists that study quantum mechanics also suggest pairs of virtual particles, each consisting of a particle and its antiparticle, can wink in and out of seemingly empty vacuum and influence their surroundings.
In their newest research scientists managed to manipulate qubits in quantum computers with lasers and this made them more advanced and faster in calculations.
"The field of experimental quantum computing is growing very fast, and many people ask the question, What is a small-scale quantum computer good for?" study co-lead author Esteban Martinez, an experimental physicist at the University of Innsbruck in Austria, told Live Science. "Unlike other applications, you don't need millions of quantum bits to do these simulations — tens might be enough to tackle problems that we cannot yet attack using classical approaches."
So far, quantum computers, when given a certain task about predicting things, did it with great accuracy and that's why scientists want to give them a try with space creation. They also predict that in the near future quantum computers could be used as a substitute to hadron colliders, as the one used in Cern.
