On the dynamics of gravity induced wave function reduction

Faramarz Rahmani, Mehdi Golshani

In this study, we use the concept of Bohmian trajectories to present a dynamical and deterministic interpretation for the gravity induced wave function reduction. We shall classify…

Coherence Based Characterization of Macroscopic Quantumness

Moein Naseri, Sadegh Raeisi

One of the most elusive problems in quantum mechanics is the transition between classical and quantum physics. This problem can be traced back to the Schrödinger's cat. A key eleme…

Modified Bohmian quantum potential due to the second quantization of Schrodinger equation

Mohammad Jamali, Mehdi Golshani, Yousef Jamali

A causal interpretation of the quantum world needs second quantization in order to cover phenomena like creation and annihilation of particles, and this leads to quantum field theo…

Fast multi-qubit gates by adiabatic evolution in interacting excited state manifolds

Mohammadsadegh Khazali, Klaus Mølmer

Quantum computing and quantum simulation can be implemented by concatenation of one- and two-qubit gates and interactions. For most physical implementations, however, it may be adv…

QBism Is Not So Simply Dismissed

Ali Barzegar

QBism is one of the main candidates for an epistemic interpretation of quantum mechanics. According to QBism, the quantum state or the wavefunction represents the subjective degree…

Bath assisted transport in a three-site spin chain: global {\sl vs} local approach

Fabio Benatti, Roberto Floreanini, Laleh Memarzadeh

Within the standard weak-coupling limit, the reduced dynamics of open quantum spin chains with their two end spins coupled to two distinct heat baths at different temperatures are…

Planar Maximally Entangled States

Mehregan Doroudiani, Vahid Karimipour

We construct a large family of Planar Maximally Entangled (PME) states which are a wider class of multi-partite entangled states than Absolutely Maximally Entangled (AME) states. T…

Protecting an unknown qubit state by weak measurement

Ozra Heibati, Azam Mani, Esfandiar Faizi +1

The problem of combating de-coherence by weak measurements has already been studied for the amplitude damping channel and for specific input states. We generalize this to a large f…
