Nanostructures with superconducting electrons are highly intriguing artificial systems that in many ways mimic naturally occurring atoms. One potential use of these artificial atoms is to implement quantum bits (qubits in short) – the basic logical units of quantum computing. |

An important aspect of quantum technology development is to maintain the coherence between qubits with a super correlation between them – entanglement. The invented wave-qubit hybrids are a novel type of a hybrid quantum system that can be used to produce quantum gates (such as a phase gate) and that are essential for quantum logic operations. It is possible that this new architecture can be scaled to produce much larger networks, which essentially will consist of multiple groups of resonators with embedded qubits and therefore will operate without adverse background noise that destroys the quantum state. |

"Quantum computation using artificial-atoms can be sensitively controlled by external electromagnetic fields" Dr. Michael Forrester, a Research Associate in the Chemical Engineering department at Loughborough University, explains to Nanowerk. "These fields and the self-fields attributable to the coupled artificial-atoms influence the amount of quantum correlation in the system. However, control elements that can operate without complete destruction of the entanglement of the quantum-bits are difficult to engineer." |
