Demonstration of Conditional Quantum Phase Shift Between Ions in a Solid
Demonstration of Conditional Quantum Phase Shift Between Ions in a Solid
Because of their long coherence times, dopant ions have been considered promising candidates for scalable solid state quantum computing. Here we demonstrate a conditional phase shift between two qubits based on an optical transition of europium ions. The demonstration uses ensembles that have been selected from a randomly doped sample …
