The preferred-time problem in the conditional interpretation of time
Ovidiu Cristinel Stoica
In timeless formulations of quantum theory, the Page-Wootters proposal (PW) recovers time and dynamics as relative clock-and-world states. By interpreting the total timeless system…
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 obs…
No change in Hilbert space fundamentalism
Ovidiu Cristinel Stoica
Hilbert space fundamentalism (HSF) states that everything about the physical world is encoded in the Hamiltonian operator and the state vector (as a unit vector, not a wavefunction…
What makes you an observer?
Ovidiu Cristinel Stoica
Both empirical and theoretical objective science can only access relations, revealing nothing about the intrinsic nature of the entities "in relation". We typically refer to these…
Observation as Physication. A single-world unitary no-conspiracy interpretation of quantum mechanics
Ovidiu Cristinel Stoica
The physical meaning of the operators is not reducible to the intrinsic relations of the quantum system, since unitary transformations can find other operators satisfying the exact…
Classical Many-Worlds Interpretation
Ovidiu Cristinel Stoica
I present a simple baby-steps reconstruction of quantum mechanics as a fully classical theory. The most radical conceptual leap required is that there are many coexisting classical…
Sentient observers and the ontology of spacetime
Ovidiu Cristinel Stoica
I show that, by the same criteria that led to Galilean and Special Relativity and gauge symmetries, there is no way to identify a unique set of observables that give the structure…
Can we accurately read or write quantum data?
Ovidiu Cristinel Stoica
Applications of quantum mechanics rely on the accuracy of reading and writing data. This requires accurate measurements and preparations of the quantum states. I show that accurate…
Does the Hamiltonian determine the tensor product structure and the 3d space?
Ovidiu Cristinel Stoica
It was proposed that the tensor product structure of the Hilbert space is uniquely determined by the Hamiltonian's spectrum, for most finite-dimensional cases satisfying certain co…
The prince and the pauper. A quantum paradox of Hilbert-space fundamentalism
Ovidiu Cristinel Stoica
The quantum world is described by a unit vector in the Hilbert space and the Hamiltonian. Do these abstract basis-independent objects give a complete description of the physical wo…
Are observers reducible to structures?
Ovidiu Cristinel Stoica
Physical systems are characterized by their structure and dynamics. But the physical laws only express relations, and their symmetries allow any possible relational structure to be…
The Friedmann-Lemaitre-Robertson-Walker Big Bang singularities are well behaved
Ovidiu-Cristinel Stoica
We show that the Big Bang singularity of the Friedmann-Lemaitre-Robertson-Walker model does not raise major problems to General Relativity. We prove a theorem showing that the Eins…
