Steps are moving science and technology towards functioning quantum computers. There are many obstacles, however; not least because quantum world is fragile. In this ...

Quantum computers have the potential to vastly exceed the capabilities of conventional computers for certain tasks. But there is still a long way to go before they can help to solve real-world ...

Millions of quantum bits are required for quantum computers to prove useful in practical applications. But this is still a long way off. One problem is that the qubits have to be very close to each ...

Magnons are tiny waves in magnetization that travel through solid magnetic materials, much like the ripples that spread across a pond when a stone is thrown into it. Unlike photons, which travel ...

October 22, 2012. In yet another step toward the realization of a practical quantum computer, scientists working at Princeton and the Joint Quantum Institute (JQI) have shown how a major hurdle in ...

NV centers have long coherence time which is good, but this is because they do not couple strongly to the environment or each other. Spin interactions are inherently weak. Because of this, it's ...

For the first time the components that underlie quantum computing’s great potential – qubits – have been linked on chips like those in conventional computers. Two US research teams used ...

Millions of quantum bits are required for quantum computers to prove useful in practical applications. The scalability is one of the greatest challenges in the development of future devices. One ...
