Quantum Breakthrough: Researchers Demonstrate Full Control of a Three-Qubit System
Researchers from RIKEN in Japan have made a critical step toward large-scale quantum computing by showing error correction in a three-qubit silicon-based quantum computing device. This study, which was reported in the journal Nature, may contribute to the development of useful quantum computers. Because they promise to resolve significant issues that can't be resolved by conventional computers, quantum computers are currently a hot topic of research. They use superimposition states of quantum physics in place of the simple 1 or 0 binary bits seen in conventional computers. Due to their fundamentally different construction, they are however extremely vulnerable to background noise and other issues, such as decoherence, and require error correction to do accurate calculations. Choosing the optimal systems to act as the "qubits," or fundamental components required to do quantum calculations, is a difficult task at the moment. Every potential system has benefits and drawbacks...
