Sandia National Laboratories' QSCOUT system demonstrates how trapped Yb-171 ion chains enable native all-to-all connectivity, eliminating the need for complex swap networks required by many other architectures. By leveraging collective motional modes as qumodes and implementing a hybrid continuous-discrete gate set via Jaqal, this approach offers distinct advantages in scaling quantum processors while maintaining precise control over individual qubits within a single linear array.
How QSCOUT Achieves All-to-All Connectivity With Yb-171 Ion Chains
QSCOUT, a trapped-ion quantum processor, uses a linear chain of Yb-171 ions for all-to-all qubit connectivity.
Sandia National Laboratories has developed an approach to quantum processing with QSCOUT, a trapped-ion system employing a linear chain of Yb-171 ions as its qubit register. This choice of isotope establishes a foundation for precise control, and the architecture provides all-to-all qubit connectivity, a potentially significant advantage because it allows any qubit to directly interact with any other within the chain. QSCOUT utilizes qubit states defined by a transition energy of approximately 12.6 GHz, requiring precise microwave technology for control. The team reports developing a qubit-boson gate set for hybrid continuous-discrete variable quantum computing, utilizing Jaqal to operate the system and offering pulse-level control through the JaqalPaw interface.
