Progress of electromagnetically induced transparency based on superconducting qubits

Superconducting quantum computing is currently considered as one of the most promising options to realize a quantum computer. Superconducting qubit is the core component of the superconducting quantum computer. To increase the decoherence time of superconducting qubits as far as possible, the large-scale integration of superconducting qubits have become the main research topic of superconducting quantum computing. As a macroscopic artificial atom, lots of quantum optical phenomena can be observed in the superconducting qubits. Electromagnetically induced transparency based on superconducting qubits can provide a new method to study the superconducting qubit decoherence mechanism, and can also arouse new ideas to study the nonlinear optics, optical storage, ultra-slow optical transmission and quantum optics. In this paper, we introduce a theoretical basis of electromagnetically induced transparency, review the current research of electromagnetically induced transparency based on superconducting qubits, compare the difference between electromagnetically induced transparencies based on gas atoms and superconducting qubits, and evaluat the prospect applications for its development.
