ND-Photonic QRNGs in a Noisy Environment

J. M. Agüero Trejo, Cristian S. Calude, O. C. Stoica

Standard pseudo-random generators have weaknesses that have led to the development of quantum random number generators (QRNGs). However, common QRNG validation methods, whether bas…

Emergent cosmology and gravity from quantum time?

Ovidiu Cristinel Stoica

Macroscopic observables allow the recovery of intrinsic dynamics from stationary quantum states. I show that, by interpreting the squared amplitude as the probability density for e…

Exact quantum time compatible with positive energy

Ovidiu Cristinel Stoica

What would it be like to be in a superposition of yesterday, today, and tomorrow? This question may seem at best entertaining, but it is necessary, and exploring it allows us to un…

The clock ambiguity problem: extended or extinguished?

Ovidiu Cristinel Stoica

I show that the clock ambiguity cannot be solved by a purely relational condition like the noninteraction condition, and it is even stronger, extending to evolution laws. The ambig…

Testing the 3D QRNG by Undoing

J. M. Agüero Trejo, Cristian S. Calude, O. C. Stoica

We propose a method to test whether a photonic 3D QRNG works according to the underlying theory, thereby generating highly incomputable/unpredictable sequences of random digits. Th…

Comment on "On the emergence of preferred structures in quantum theory" by Soulas, Franzmann, and Di Biagio

Ovidiu Cristinel Stoica

This reply is also a friendly introduction to the impossibility of emergence of preferred structures from the Hamiltonian and the unit vector only. The ob…
