Demonstration of quantum entanglement
With the advancement of quantum computers it is very much tempting to experience the laws of physics without having to build sophisticated apparatus on our own. The following experiment demonstrates the existence of phenomena of quantum entanglement as we know it.
Quantum Entanglement
Quantum entanglement is a physical phenomenon which occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the other(s), even when the particles are separated by a large distance instead, a quantum state must be described for the system as a whole.
Entanglement is considered fundamental to quantum mechanics, even though it wasn’t recognized in the beginning. Quantum entanglement has been demonstrated experimentally with photons, neutrinos, electrons, molecules as large as buckyballs, and even small diamonds. The utilization of entanglement in communication and computation is a very active area of research.
Experiment
The project is an experiment designed to demonstrate the awesome phenomena of quantum entanglement. The main motive behind this project is to dive more into the upcoming technology (Quantum Computing).
The experiment was done on the ibmqx4 processor and below are the conditions, circuit design and results of the experiment.

As the result confirms the occurrence of the qubit in a pattern of XXXY or XXYX ( X=0|1 Y=0|1 ) which indicate the change in qubit[0] with respect to qubit[1] in other words qubit[0] and qubit[1] are entangled together.
