Experimental test of the quantum no-hiding theorem.
The no-hiding theorem says that if any physical process leads to bleaching of quantum information from the original system, then it must reside in the rest of the Universe with no information being hidden in the correlation between these two subsystems. Here, we report an experimental test of the no-hiding theorem with the technique of nuclear magnetic resonance. We use the quantum state random...
متن کاملNo Quantum Brooks' Theorem
First, I introduce quantum graph theory. I also discuss a known lower bound on the independence numbers and derive from it an upper bound on the chromatic numbers of quantum graphs. Then, I construct a family of quantum graphs that can be described as tropical, cyclical, and commutative. I also define a step logarithm function and express with it the bounds on quantum graph invariants in closed...
متن کاملQuantum copying: Beyond the no-cloning theorem.
We analyze a possibility of copying (≡ cloning) of arbitrary states of quantum-mechanical spin1/2 system. We show that there exists a “universal quantum-copying machine” (i.e. transformation) which approximately copies quantum-mechanical states such that the quality of its output does not depend on the input. We also examine a machine which combines a unitary transformation and a selective meas...
متن کاملExperimental test of the no-go theorem for continuous ψ-epistemic models
Quantum states are the key mathematical objects in quantum theory; however, there is still much debate concerning what a quantum state truly represents. One such century-old debate is whether a quantum state is ontic or epistemic. Recently, a no-go theorem was proposed, stating that the continuous ψ-epistemic models cannot reproduce the measurement statistic of quantum states. Here we experimen...
متن کاملNo-splitting Theorem: Principles of Quantum Information
In the context of quantum information there arise a number of interesting questions regarding the domains of operations which are feasible in classical context to be applicable in quantum information domain or not. The criterion of feasibility and non feasibility of various physical processes in quantum regime creates a set of impossible operations[1-6]. This may be probably due to the linear s...
