Explore the fascinating world of quantum mechanics and superconductivity in this lecture on mechanically assisted Andreev reflection. Delve into the concept of Coulomb blockade and its removal through electrostatic means, leading to entanglement between superconducting condensates. Learn about Cooper pair box (CPB) states and their role in implementing qubits for quantum information processing. Discover how time-dependent mechanical displacement of a superconducting dot enables spatial transportation of CPB states, creating "flying qubit states." Examine the process of observing these states through electron injection from external non-superconducting electrodes. Investigate the phenomenon of Andreev reflection and its connection to mechanical motion of CPB and movable qubit states. Analyze the relationship between electric current, zero driving voltage, and the oscillatory dependence on electrostatic gate potential in this cutting-edge research presented by Leonid Gorelik from the PCS Institute for Basic Science.
