| description | Quantum information: improving semiconducting qubit performance Researchers in the United States demonstrate high tunability of spin qubits in silicon-based quantum dots. Mark Eriksson at the University of Wisconsin-Madison and colleagues have achieved more than a tenfold improvement in the performance of these three-electron double dot qubits by tuning the electric fields used to confine electrons to quantum dots to a regime where the qubit was predicted to be much less susceptible to the effects of charge noise. Since charge noise limits the performance of many such qubits, these findings provide a path toward the fabrication of electrically gated qubits in silicon quantum dots with very high fidelities. |
