... the momentum variable. Although straightforward, the momentum distribution is difficult to visualize if one only has 共x兲. It would be desirable to have a function that displays the probability distribution simultaneously in the x and p variables. The Wigner function, introduced by Wigner in 1932,1 ...

Implementation of a Toffoli gate with superconducting circuits
... resonator, in a sample that is identical to the one used in ref. 14. The resonator is used for joint three-qubit read-out by measuring its transmission18. At the same time, it serves as a coupling bus for the qubits19. The qubits have a ladder-type energy level structure with sufficient anharmonicit ...

Quantum Heat Engines and Refrigerators: Continuous Devices
... of hypothetical quantum heat engines and refrigerators to address these issues. Once understood, these models serve as a template for real devices. Gedanken heat engines are an integral part of thermodynamical theory. In 1824, Carnot (1) set the stage by analyzing an ideal engine. His analysis prece ...
