The Bell states, a concept in quantum information science, are specific quantum states of two qubits that represent the simplest (and maximal) examples of quantum entanglement. The Bell states are a form of entangled and normalized basis vectors. Understanding of the Bell states is essential in analysis of quantum communication (such as superdense coding) and quantum teleportation.

Goals

To play with around the sample code given by the QDK kit to understand how different quantum operations are executed in Q#, and how a simple entanglement of two Qbits can be created using the Hadamard and CNOT gate

I'm writing this README to keep a log of concepts I learnt after going through some concepts of QComputing and Microsoft's QDK

Concepts

The bell state is the simplest representation of entanglement. The pair of QBits are put in the Bell state with the following quantum operations:

Q# Gist

Essentially, we create two QBits and apply the gates to entangle them.

  qubits = Qubit[2]
  H(qubits[0]);
  CNOT(qubits[0],qubits[1]);

Microsoft's Quantum Development Kit

This project was built and run using Microsoft's QDK.
