Quantum Metrology [PDF]

open access: yesPhysical Review Letters, 2006
We point out a general framework that encompasses most cases in which quantum effects enable an increase in precision when estimating a parameter (quantum metrology). The typical quantum precision-enhancement is of the order of the square root of the number of times the system is sampled.

Quantum transformations [PDF]

open access: yesPhysics Letters A, 1998
We show that the stationary quantum Hamilton-Jacobi equation of non-relativistic 1D systems, underlying Bohmian mechanics, takes the classical form with $\partial_q$ replaced by $\partial_{\hat q}$ where $d\hat q={dq\over \sqrt{1- ^2}}$. The $ ^2$ term essentially coincides with the quantum potential that, like $V-E$, turns out to be proportional to ...

QUANTUM DILOGARITHM [PDF]

open access: yesModern Physics Letters A, 1994
A quantum generalization of Rogers’ five-term, or “pentagon” dilogarithm identity is suggested. It is shown that the classical limit gives the usual Rogers’ identity. The case where the quantum identity is realized in finite-dimensional space is also considered and the quantum dilogarithm is constructed as a function on Fermat curve, while the ...

Quantum Computation Toward Quantum Gravity [PDF]

open access: yesGeneral Relativity and Gravitation, 2001
The aim of this paper is to enlight the emerging relevance of Quantum Information Theory in the field of Quantum Gravity. As it was suggested by J. A. Wheeler, information theory must play a relevant role in understanding the foundations of Quantum Mechanics (the "It from bit" proposal).
