Manipulations of a transmon qubit with a null-biased electro-optic fiber link.

ABSTRACT: In recent years, significant progress has been made in the field of superconducting quantum circuits, particularly in improving the complexity of quantum processors for large-scale quantum computing and quantum simulation tasks. To enable the execution of quantum information processing tasks on large-scale quantum circuits containing millions of qubits, it is essential to minimize thermal effects on control and measurement lines, ensuring that circuit components are superconducting and that qubits are not significantly thermally excited. Recent studies have shown that a quadrature-biased electro-optic fiber link can operate qubits with a much reduced thermal load, thereby facilitating the simultaneous operation of a large number of qubits. Expanding on this, here we propose and demonstrate
