Error-free into the quantum computer age

A study led by physicists at Swansea University in Wales, carried out by an international team of researchers and published in the journal Physical Review X shows that ion-trap technologies available today are suitable for ...

Researchers successfully demonstrate a quantum gate in silicon

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit systems made of silicon. ...

Simple is beautiful in quantum computing

Quantum computing could solve problems impossible for today's supercomputers. The challenge for this new form of computing is processing the quantum bits (qubits) that represent data. A qubit can be made by controlling the ...

Quantum computing on the move

A future quantum computer, using quantum bits, or qubits, might be able to solve problems that are not tractable for classical computers. Scientists are currently struggling to build devices with more than a few qubits, as ...

A new kind of quantum computer

Quantum mechanics incorporates some very non-intuitive properties of matter. Quantum superposition, for example, allows an atom to be simultaneously in two different states with its spin axis pointed both up and down, or ...

Flip-flop qubits: Radical new quantum computing design invented

Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips ...
