Chip-to-chip entanglement of transmon qubits using engineered measurement fields
Chip-to-chip entanglement of transmon qubits using engineered measurement fields
While the on-chip processing power in circuit QED devices is growing rapidly, an open challenge is to establish high-fidelity quantum links between qubits on different chips. Here, we show entanglement between transmon qubits on different cQED chips with $49%$ concurrence and $73%$ Bell-state fidelity. We engineer a half-parity measurement by …
