While quantum computers exist in the physical world, the concept of the quantum internet is currently theoretical. Existing quantum networks currently don't expand beyond research rooms, but they relate toquantum computing. For example, the quantum internet is based on quantum mechanical phenomena...
perhaps exponentially. Here we consider a prototypical PDE—the heat equation in a rectangular region—and compare in detail the complexities of ten classical and quantum algorithms for solving it, in the sense of approximately computing the amount of heat in a given region. We find ...

(ii) Quantum branching programsreading each input variable exactly once are shown to require size2^{\\Omega(n)} for computing the set-disjointness function DISJ_n fromcommunication complexity theory with two-sided error bounded by a constantsmaller than 1/2-2\\sqrt{3}/7. This function is ...

If it is true, the hardness results on sampling would not be physically detectable like clas- sical analog computing with unlimited-precision real numbers, which can solve NP complete and even PSPACE complete problems21,22. To tackle this issue, we directly show that commuting quantum circuits ...
Quantum Decoherence in bipartite correlated Qutrit Systems F. A. Cárdenas-López, S. Allende & J. C. Retamal Classical to quantum decoherence transition, an issue existing for incoherent superposition of Bell- diagonal states is studied for three dimensional bipartite AB mixed quantum ...
So far, due to the laws of quantum physics, no classical correlations are applied to the quantum spectrum. However, conversely, quantum correlations are applied in classical environments such as quantum computing, cryptography, metrology, teleportation, medical imaging, laser technology, the quantum ...
