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

The power of optical lattices for quantum simulation and computation is greatly enhanced when atoms at individual lattice sites can be accessed for measurement and control. Experiments routinely ...

The study, carried out at the Institute of Quantum Electronics at (ETH)–Zürich and the University of Cambridge, describes 2 a setup that uses a pair of quantum dots to achieve a phase shift gate.

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 ...

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.

They showed that quantum gates could be controlled based on mid-circuit measurements, enhancing qubit connectivity. This approach allowed multiple processors to function as unified, improving ...

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 ...

A higher current that occurs first is due to more dangling bonds. By repeating this process for many pairs of transistor gates, we can create a PUF random number since we never know where we will see ...
