Tight bounds for LDPC and LDGM codes under MAP decoding
Conditional entropy Low Density Parity Check Codes Maximum A Posteriori probability decoding Spin glasses Statistical physics
2015/8/21
A new method for analyzing low density parity check (LDPC) codes and low density generator matrix (LDGM) codes under bit maximum a posteriori probability (MAP) decoding is introduced. The method is ba...
Positivity bounds for the Yano-Arnowitt-Deser-Misner mass density
Vector conservation of gravity mass density energy
2014/12/20
Killing-Yano tensors are natural generalizations of Killing vectors to arbitrary rank antisymmetric tensor fields. It was recently shown that Killing-Yano tensors lead to conserved gravitational charg...
Explicit Bounds for Entropy Concentration under Linear Constraints
maximum entropy concentration bounds linear constraints tolerances
2011/8/19
Abstract: Consider the construction of an object composed of $m$ parts by distributing $n$ units to those parts. For example, say we are assigning $n$ balls to $m$ boxes. Each assignment results in a ...
Prospects of coherent control in turbid media: Bounds on focusing broadband laser pulses
Prospects coherent control turbid media broadband laser pulses
2011/8/11
Abstract: We study the prospects of controlling transmission of broadband and bi-chromatic laser pulses through turbid samples. The ability to focus transmitted broadband light is limited via both the...
Calculation and Application of New Quantum Bounds
Calculation New Quantum Bounds determines arbitrary Quantum Bounds algorithm
2011/7/27
Abstract: We review, correct, and develop an algorithm which determines arbitrary Quantum Bounds, based on the seminal work of Tsirelson [Lett. Math. Phys. 4, 93 (1980)]. The vast potential of this al...

Higgs boson mass bounds fourth quark generation
2011/1/13
We study the effect of a potential fourth quark generation on the upper and lower Higgs boson
mass bounds. This investigation is based on the numerical evaluation of a chirally invariant lattice Higg...
We study the entanglement of formation for arbitrary dimensional bipartite mixed unknown states. Experimentally measurable lower and upper bounds for entanglement of formation are derived.
Properties and upper continuity bounds of relative $q$-entropy for $1
Properties upper continuity bounds relative $q$-entropy $1
2010/11/9
The notion of quantum Tsallis relative $q$-entropy is extended to values $q>1$ in the finite-dimensional context. We examine basic properties including their treatment in the singular case. The nonneg...
Measurement of damping and temperature: Precision bounds in Gaussian dissipative channels
Measurement damping temperature Precision bounds Gaussian dissipative channels
2010/10/29
We present a comprehensive analysis of the performance of different classes of Gaussian states in the estimation of Gaussian phase-insensitive dissipative channels. In particular, we investigate the ...
Tight Bounds for Classical and Quantum Coin Flipping
Tight Bounds for Classical Quantum Coin Flipping
2010/10/21
Coin flipping is a cryptographic primitive for which strictly better protocols exist if the
players are not only allowed to exchange classical, but also quantum messages. During the past
few years, ...
In any static spacetime the quasilocal Tolman mass contained within a volume can be reduced to a Gauss-like surface integral involving the flux of a suitably defined generalized surface gravity. By in...

Ultimate quantum bounds mass measurements nano-mechanical oscillator
2010/10/21
Nano-mechanical resonators have a large potential as sensors of very small adsorbed masses,
down to the atomic level and beyond. Here I establish the fundamental lower bound on the mass
that can be ...

2009/8/17
Using Breit-Wigner resonance relation, bounds on the magnetic moment of the
tau-neutrino are calculated through the reaction e+e－→ννγ at the neutral boson pole in the framework of a superstring-inspi...
