Abstract

In Hall’s reformulation of the uncertainty principle, the entropic uncertainty relation occupies a core position and provides the first nontrivial bound for the information exclusion principle. Based upon recent developments on the uncertainty relation, we present new bounds for the information exclusion relation using majorization theory and combinatoric techniques, which reveal further characteristic properties of the overlap matrix between the measurements.

Highlights

  • In Hall’s reformulation of the uncertainty principle, the entropic uncertainty relation occupies a core position and provides the first nontrivial bound for the information exclusion principle

  • The sum of information corresponding to measurements of position and momentum is bounded by the quantity log2ΔXΔPX/ħ; for a quantum system with uncertainties for complementary observables ΔX and ΔPX, and this is equivalent to one form of the Heisenberg uncertainty principle10

  • For observables M1, M2, ..., MN, where r(M1, M2, ..., MN, B) is a nontrivial quantum bound. Such a quantum bound is recently given by Zhang et al.18 for the information exclusion principle of multi-measurements in the presence of the quantum memory

Summary

Introduction

In Hall’s reformulation of the uncertainty principle, the entropic uncertainty relation occupies a core position and provides the first nontrivial bound for the information exclusion principle. The sum of information corresponding to measurements of position and momentum is bounded by the quantity log2ΔXΔPX/ħ; for a quantum system with uncertainties for complementary observables ΔX and ΔPX, and this is equivalent to one form of the Heisenberg uncertainty principle. The sum of information corresponding to measurements of position and momentum is bounded by the quantity log2ΔXΔPX/ħ; for a quantum system with uncertainties for complementary observables ΔX and ΔPX, and this is equivalent to one form of the Heisenberg uncertainty principle10 Both the uncertainty relation and information exclusion relation have been used to study the complementarity of obervables such as position and momentum. For observables M1, M2, ..., MN, where r(M1, M2, ..., MN, B) is a nontrivial quantum bound Such a quantum bound is recently given by Zhang et al. for the information exclusion principle of multi-measurements in the presence of the quantum memory. Almost all available bounds are not tight even for the case of two observables
