The fifth lecture "Superconducting quantum processors: State of the art and challenges" in "Open RQC colloquium" will be held in National University of Science and Technology MISIS (Moscow, Leninskiy prospekt 4), lecture hall № Б-534 (5th floor), on 15th of July at 10:00 a.m by Alexey Ustinov, Head of laboratory of superconducting metamaterials, Professor in Karlsruhe Institute of Technology (Germany) and Superconducting Quantum Circuits group lead in RQC.


Superconducting quantum processors are circuits comprising Josephson junctions interconnected through inductors and capacitors. At temperatures below 0.1K, the elementary blocks of these circuits, superconducting qubits, behave as quantum mechanical "artificial atoms” exhibiting quantized states separated by energies of few micro-eV. Depending on the design parameters, these states are defined by either electronic charge or phase drop across Josephson junction. For a Josephson junction, the phase drop and the charge are quantum-mechanical conjugate variables. There exist several families of superconducting qubits including charge qubits, flux qubits, and their variations. Qubit quantum states can be prepared and manipulated by microwave pulses. In the lecture I will discuss the decoherence sources for superconducting qubits, address challenges to scale them up, and mention several state-of-the-art examples of quantum information processing.
