A Two-Qubit Quantum Processor in Silicon

In collaboration with the group of Lieven Vandersypen, TU Delft, we demonstrate a two-fully programmable two-qubit quantum processor in a pair of tunnel-coupled Si/SiGe gate-defined quantum dots.   “A programmable two-qubit quantum processor in silicon.” T.
