Scalable generation of genuine multiparticle entanglement with superconducting qubits

ORAL

Abstract

Solid state qubits by their nature are a scalable technology, but the number of entangled qubits still trails the size of state-of-the-art systems considerably. Producing large entangled states requires many different measures of processor quality to be high simultaneously: coherence times and tunability must be high; crosstalk and state leakage must be minimized. In addition, gate operations need to be specifically calibrated to create entanglement. In this work, based only on single-qubit gates and controlled-phase gates, we generated and verified the genuine multiparticle entanglement for more than 10 superconducting qubits. This gate-based approach to entanglement generation is directly scalable to larger systems. Our result is an important step towards achieving near-term quantum supremacy.
