This paper discusses the creation of a new qubit, ‘Plasmonium’, offering features superior to traditional transmon qubits. It’s designed using variational quantum eigensolvers to showcase an advanced quantum processor concept.

• Exhibits higher gate fidelities and anharmonicity.
• Smaller size which may facilitate the scaling of multi-qubit systems.
• Employs a novel quantum-aided design technique.

Relevance: ‘Plasmonium’ paves the way for next-generation quantum processors by offering optimized performance metrics crucial for scaling and operating quantum computers.
