Square Root of “Not”
... • Main result: in spite of the seeming similarity between the two logics, they are different. • They are different in square root of “not” – crucial for speed-up of quantum computing. • This difference is not unexpected: – fuzzy logic is a human way of reasoning about the real-world phenomena; – mos ...

Operator Quantum Error Correction.
... map will also be noiseless for any other map whose Kraus operators are linear combinations of the Kraus operators of the original map. Hence, for the purpose of noiseless encoding, any map whose Kraus operators span is closed under conjugation is equivalent to a unital map. The mathematical framewor ...

NP-complete Problems and Physical Reality
... Throughout the article, I assume basic familiarity with complexity classes such as P and NP (although not much more than that). Sometimes I do invoke elementary physics concepts, but the difficulty of the physics is limited by my own ignorance. After reviewing the basics of P versus NP in Section 2, ...

Superconducting Circuits and Quantum Computation T. P. Orlando
... Qubit interaction is necessary for operations such as a CNOT gate that is necessary for the universal set of quantum gates of quantum computation. But qubit interaction also introduces operational errors by additional transition matrix elements during gate operations. By mapping the interacting qubi ...

... into destructive interference and hence causes an enhanced conductance, i.e. AL. Recently, weak AL has been reconsidered in a number of corresponding experiments, both for GaAs- [9] and InAs-based [6, 10, 11] two-dimensional (2d) electron gases, as well as for ballistic quantum dots [12, 13]. While ...

Dynamics of Quantum Many Body Systems Far From Thermal
... We start the discussion from a very general and qualitative definition of what thermal equilibrium is. We could say that a macroscopic system is said to be in thermal equilibrium when • its state (physical properties) is defined in terms of a unique set of intensive and extensive variables which do ...
