Scaling of macroscopic superpositions close to a quantum phase transition
Tahereh Abad, Vahid Karimipour
It is well known that in a quantum phase transition (QPT), entanglement remains short ranged [Osterloh et al., Nature 416 608-610 (2005)]. We ask if there is a quantum property ent…
Investigation of quantum entanglement simulation by random variables theories augmented by either classical communication or nonlocal effects
A. Fahmi
Bell's theorem states that quantum mechanics is not a locally causal theory. This state is often interpreted as nonlocality in quantum mechanics. Toner and Bacon [Phys. Rev. Lett.…
Dynamically contracted algebra of observables for dissipative quantum systems
Sahar Alipour, Dariusz Chruściński, Paolo Facchi +3
A method is discussed to analyze the dynamics of a dissipative quantum system. The method hinges upon the definition of an alternative (time-dependent) product among the observable…
No-iteration of unknown quantum gates
Mehdi Soleimanifar, Vahid Karimipour
We propose a new no-go theorem by proving the impossibility of constructing a deterministic quantum circuit that iterates a unitary oracle by calling it only once. Different scheme…
On the meaning of locality: the overlapping assumptions
Afshin Shafiee, Farhad Taher Ghahramani
We examine the locality assumption of Bell's theorem in three steps of EPRB experiment. Depending on the context, locality is embodied in the conditions of separability, local caus…
Quantum imaging with undetected photons as ancilla-assisted process tomography
M. Ghalaii, M. Afsary, S. Alipour +1
We show that how a recent experiment of quantum imaging with undetected photons can basically be described as a (partial) ancilla-assisted process tomography. We propose a simplifi…
