Error-detected state transfer and entanglement in a superconducting quantum network: Part 1

ORAL

Abstract



Modular networks present a compelling approach to constructing complex quantum machines, but rapid and faithful communication between modules remains a challenge. Reliance on lossy elements such as circulators, hybrids, and connectors have prevented previous demonstrations from taking advantage of the high intrinsic quality of superconducting transmission line links between modules. Here we present an all-superconducting demountable coaxial link which supports low-loss standing-wave modes. We use one of these modes as a quantum bus, coupling two 3D cavity bosonic qubits in separate modules with parametric conversion, and construct a beamsplitter-type transformation between the two cavity modes. This talk will discuss how this flexible operation can be used for bidirectional state transfer and entanglement generation between modules.
