It effectively connects all qubits through a resonator, which is rare in superconducting technology. This resonator acts as a computational element, enabling direct, high-fidelity interactions between all qubits. A Departure from Tradition: How IQM Star Stands Apart Effective all-to-all connectivity: Any qubit can interact with any other qubit, eliminating the need for noisy SWAP gates. Improved error resilience: The shared resonator allows for more efficient quantum error detection and correction. Efficient quantum algorithm execution: Algorithms that require high qubit connectivity, such as quantum simulations and variational quantum eigensolvers (VQEs), can run more efficiently. medium (1).png 10-Qubit Entanglement and Parallel Logic Operations with a Superconducting Circuit 10.1103/PhysRevLett.119.180511 20250620-18.png Coherent Josephson Qubit Suitable for Scalable Quantum Integrated Circuits 10.1103/PhysRevLett.111.080502 20260620-28.png 10.1007/s11432-020-2881-9 Superconducting quantum computing: a review 31.Superconductingquantumcomputing_areview.pdf 20260620-27.png 10.1007/s11432-020-2881-9 Superconducting quantum computing: a review 31.Superconductingquantumcomputing_areview.pdf 20260620-26.png 10.1007/s11432-020-2881-9 Superconducting quantum computing: a review 31.Superconductingquantumcomputing_areview.pdf 20250620-25.png 10.1007/s11432-020-2881-9 Superconducting quantum computing: a review 31.Superconductingquantumcomputing_areview.pdf
