The goal of this paper is to provide a simple recipe to find such efficiently computable bounds for quantum network capacities. In this paper, using the approach taken in refs. 13,14,15,24, i.e., defining a network capacity as a rate per the total number of channel uses or per time,...

The total coherence can be ...
An anyon gas is a quantum system consisting of a large number of such particles subject to a fixed class of exchange symmetries, which is dependent on the specific underlying kinematics and dynamics of the quantum systems from which it emerged. The study of the behavior of the proper anyon ...
It is easy to see that this norm can be equivalently written as(4.4)π1,cb(Gˆ:S∞n→S1m)=supd‖11⊗Gˆ:ℓ1d⊗minS∞n→ℓ1d(S1m)‖. Let us write this norm in more detail. For each natural number d in the above supremum we have:(4.5)‖11⊗Gˆ:ℓ1d⊗minS...
It is an extremely challenging project that stacks a number of critical systems engineering fields, in particular the combination of extreme high pointing accuracy and subsequent ADCS requirements and interactions. We present the mission concept, the key challenges, and outline the systems to be ...
In normal silicon computer chips, data is rendered in one of two states: 0 or 1. However, in quantum computers, data could exist in both states simultaneously, holding exponentially more information. The computing power of a quantum computer grows exponentially with the number of quantum bits th...
For example, one can define the Rindler vacuum as a^ωR|0R⟩=0 with a^ωR being the annihilation operator for a right Rindler particle, corresponding to the solution ϕωR(χ). Here ω here is the particle frequency. The particle number state is given by (a^ωR†)nn!|0R⟩...

A number of interpretations were suggested in order to achieve a coherent picture of the observed reality both on a microscopic quantum and on a macroscopic classical level. Among them is the pilot-wave theory due to Bohm [5,6,7]. For a non-relativistic system of particles with configuration...
Random number generators include a thermal optical source and detector configured to produce random numbers based on quantum-optical intensity fluctuations. An optical flux is detec
