"extended coherence time 1.000X... qubits perform 10,000 operations over coherence time with high precision and speed... encode quantum information in the electron's motional (charge) states. Because of that, they are called charge qubits... low cost building and running large-scale quantum computers... small footprint of single electrons on solid neon (reduces disruptive signals) enables more compact qubits... 2-qubit entanglement coupled to same superconducting circuit: a critical aspect of quantum computing"
