Distinguishability, Ensemble Steering, and the No-Signaling Principle

Grover Search and the No-Signaling Principle.

Two of the key properties of quantum physics are the no-signaling principle and the Grover search lower bound. That is, despite admitting stronger-than-classical correlations, quantum mechanics does not imply superluminal signaling, and despite a form of exponential parallelism, quantum mechanics does not imply polynomial-time brute force solution of NP-complete problems. Here, we investigate t...

Local PT symmetry violates the no-signaling principle.

Bender et al. [Phys. Rev. Lett. 80, 5243 (1998)] have developed PT-symmetric quantum theory as an extension of quantum theory to non-Hermitian Hamiltonians. We show that when this model has a local PT symmetry acting on composite systems, it violates the nonsignaling principle of relativity. Since the case of global PT symmetry is known to reduce to standard quantum mechanics A. Mostafazadeh [J...

(An Analysis of Principle no.8 of the Constitution)

This article has analyzed principle no.8 of the Constitution from three aspects: 1-verbal analysis 2-conceptual analysis 3-ways to execute this principle. In first section a precise definition of "call to good", "good and evil" (both in law and in jurisprudence) and "government" have been presented. In second section to have a better understanding of principle no.8, issues such as the relation ...

No-overloading Principle

A C++ programmer said to Rabbi Shammai: " I promise to try object technology if you can explain the secret of objects while standing on one foot. " Rabbi Shammai whacked him on the head with a 10-by-2 ruler. He went to Rabbi Hillel who, standing on one foot, answered: " No overloading. That is the secret of objects. All the rest is commentary. " Some commentary now. The beauty of object technol...
