Quantum Digits Unlock More Computational Power With Fewer Quantum Particles
Quantum Computer Works With More Than Zero and One. As we all learn from early on, digital computers work with zeros and ones, also known as binary information. This approach has worked well. In fact, it has been so successful that computers now power everything from coffee machines to self-driving cars and it is difficult to imagine a life without them. Building on this incredible success, today’s quantum computers are also developed with binary information processing in mind. “The building blocks of quantum computers, however, are more than just zeros and ones,” explains Martin Ringbauer, an experimental physicist from Innsbruck, Austria. “Restricting them to binary systems prevents these devices from living up to their true potential.” A team of scientists has now succeeded in developing a quantum computer that can perform arbitrary calculations with so-called quantum digits (qudits), thereby unlocking additional computational power with fewer quantum particles. This group is led by Thomas Monz at the Department of Experimental Physics at the University of Innsbruck. Read more...
