Superconducting qubits are efficient and promising quantum objects for the development and implementation of quantum computers. Well. Currently, the most commercially successful superconducting qubits are transmons.
In a recent study to perform transmon operations, MIPT scientists developed a quantum integrated circuit (KIMS) containing five capacitive shunt charge qubits, one of which was not used in this experiment. The qubits are electrically interconnected and can both exchange energy and change the phase of the superposition of the |0⟩ and |1⟩ states in a mutually controlled manner.
The experiment was carried out on November 8 at the Moscow Institute of Physics and Technology. To implement the calibrated CZ operation with more than 97% accuracy, equipment provided by scientists from the University of Science and Technology (MISiS) and the program code previously developed by them were used to demonstrate two-qubit operations in two registers. The superconducting Fluxon qubits made this possible.
