Being able to precisely manipulate interacting spins in quantum systems is of key importance for the development of reliable and highly performing quantum computers. This has proven to be particularly ...

(a) The schematic of the fabricated ZnO device. Two-dimensional electron gas is formed between (Mg, Zn)O and ZnO. Quantum dots are formed by applying gate voltage to this two-dimensional electron gas.

To form qubit states in semiconductor materials, it requires tuning for numerous parameters. But as the number of qubits increases, the amount of parameters also increases, thereby complicating this ...

Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality.

Researchers created and controlled triple quantum dots in ZnO, advancing scalable quantum info tech and enabling studies of complex quantum behaviors. However, a large number of qubits are required ...
