Together with qubits (the quantum version of the 0/1 bit), logic gates are the basic components to construct, as in a building block game, a quantum computer. They need to be fast not only to ...

Deterministic entanglement of multiple qubits—an essential prerequisite for general quantum information processing—was first achieved nearly twenty years ago using laser manipulation of qubits ...

A team of Australian engineers has built a quantum logic gate in silicon for the first time, making calculations between two qubits of information possible. A crucial quantum computing hurdle has been ...

Electronics is the manipulation and processing of information using electrons, so it shouldn’t be hard to imagine what the emerging field of atomtronics is attempting to do. The idea is to ...

Now a team of researchers has managed to create the world’s first quantum logic gate in faithful old silicon. Engineers from the University of New South Wales have developed a device that allows ...

The realization of a full-scale quantum computer presents one of the most challenging problems facing modern science. Even implementing small-scale quantum algorithms requires a high level of ...

where single photons are generated and used to perform the controlled-NOT quantum logic gate in optical fibres with high fidelity. The only quantum technology in practical use today is quantum ...

Quantum gates are the basic arithmetic elements that make up quantum computing. They correspond to the logic gates such as AND and OR in conventional classical computers. There are one-qubit gates ...
