CP asymmetry and visible decay in neutrino oscillations on a quantum computer
Amartya Sengupta, Sidhartha Samtani, Ani Girgvliani +1
We use quantum simulation to study how visible neutrino decay modifies the vacuum CP asymmetry in muon-to-electron oscillations within a neutrino scenario. The decay channel…
A Multi-Axion Ladder Across Cosmic History: From Inflation, BBN, and Early Dark Energy to Late-Time Accelerated Expansion
Amartya Sengupta, Dejan Stojkovic, Adam G. Riess
What if dark energy is recurrent throughout cosmic history? In this picture, episodes of scalar-field dark energy become less surprising and more natural features of cosmic evoluti…
Information capacity of quantum statistics: Fock-state tests of a discrete binary-sequence model on cloud photonic quantum processors
Chiran Wijesundara, Octavia T. Volpe, Dejan Stojkovic +2
Our central premise is that quantum mechanics may be the statistical limit of a more fundamental discrete theory: any such theory equips a physical system with a finite information…
Emergent Space, Time, and Lorentz Symmetry from Binary Sequences
Sam Powers, Dejan Stojkovic
We construct an information theory framework in which the fundamental objects are binary sequences of length , equipped with the bitwise XOR operation. The only physical observa…
The quantum harmonic oscillator from binary sequences
Samuel Powers, Dino Skrgic, Dejan Stojkovic
The quantum harmonic oscillator (QHO) is normally built on a structure that contains a Hilbert space, ladder operators, and a Born rule. Here we derive it from counting. We adopt t…
Signals of Doomsday III: Cosmological signatures of the late time symmetry breaking
Amartya Sengupta, Dejan Stojkovic
Of the universe's original gauge symmetries, only (quantum chromodynamics) and (electromagnetism) remain unbroken today. There is, however, no reason to a…
