SWAP gates -- which swap information between qubits -- are often introduced in quantum circuits to facilitate interactions between information in non-adjacent qubits.

A recent study led by quantum researchers at the Department of Energy's Oak Ridge National Laboratory proved popular among the science community interested in building a more reliable quantum network.

New quantum dot logic gates a step towards quantum computers A pair of articles in this week's edition of Science look at creating a form … ...

By leveraging virtual gates and real-time classical links, this work opens pathways for scalable and error-mitigated quantum computing with modular quantum processors.

If this control qubit is in the ground state, no photons between the two cavities swap, but if the control qubit is excited, the states in the cavities change places. This so-called controlled-SWAP ...

Researchers have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state.

Coupled quantum dots can be an important building block in the development of scalable quantum devices by controlling the quantum states of two adjacent quantum dots (QDs) electrically and optically.

The multiqubit register signifies important progress in quantum-information processing, which requires a large number of qubits. Realizing multiqubit registers is challenging for two reasons: the ...

As a result, we can take the advantages of these intrinsic microstructure differences to create the PUF number. To do so, we need to apply high electrical field to two adjacent transistor gates in ...
