Understanding Robust Catalytic Computing
Michal Koucký, Ian Mertz, Sasha Sami
Catalytic computing concerns space bounded computation which starts with memory full of data that have to be restored by the end of the computation. Lossy catalytic computing, defi…
Collapsing Catalytic Classes
Michal Koucký, Ian Mertz, Edward Pyne +1
A catalytic machine is a space-bounded Turing machine with additional access to a second, much larger work tape, with the caveat that this tape is full, and its contents must be pr…
A note on superposition of two unknown states using Deutsch CTC model
Sasha Sami, Indranil Chakrabarty
In a recent work, authors prove a yet another no-go theorem that forbids the existence of a universal probabilistic quantum protocol producing a superposition of two unknown quantu…
Complementarity of genuine multipartite non-locality
Sasha Sami, Anubhav Chaturvedi, Indranil Chakrabarty
We introduce a new feature of no-signaling (Bell) non-local theories, namely, when a system of multiple parties manifests genuine non-local correlation, then there cannot be arbitr…
diagnostic applied to scalar field models and slowing down of cosmic acceleration
M. Shahalam, Sasha Sami, Abhineet Agarwal
We apply the diagnostic to models for dark energy based on scalar fields. In case of the power law potentials, we demonstrate the possibility of slowing down the expansion of…
