Abstract We develop an efficient scheme for controllably generating electromagnetically induced transparency (EIT) with a superconducting qutrit driven by tunable drivings. At an optimal bias point, the first three level states of a charge-phase quantum circuit constitute our qutrit. Allowed by the level transition rule, V- and -type interactions between the qutrit and driving fields can be obtained individually. By the technique of density matrix, we analytically derive and numerically address two cases of EIT for an identical probe field only by tuning the frequency of control driving. Thanks to the tunable interactions within the qutrit having sufficient level anharmonicity, our strategy offers a promising approach to generate EIT in a controllable manner, which could be highly preferable to experimentally investigate EIT with superconducting artificial atoms.
