Tutorial 4 - universal quantum computation (part 2)

Two-qubit gates and entangling blocks

This lecture builds upon the lecture hosted on 29.04.2021. We shall revisit fundamental quantum operations that are required in universal quantum computation. I will particularly talk about digital quantum computation, and introduce basic two qubit gates. 

In part 2, you will learn the definitions and implementations of CNOT and CPHASE gates. We will perform operations on two qubits using these gates on qutip. I will demonstrate how one can, for instance, create a superposition states using H gate. I will also demonstrate how one can entangle a pair of qubits using H and CNOT gates. Entanglement is unique to quantum particles; Einstein once infamously described it as a "spooky action at a distance".

Quantum computing projects on offer!

We are also providing fun quantum computing projects to our OQN members. These projects are to be completed in the time frame of 1-2 months. We will use qutip as well as strangeworks platforms to carry out these projects. Projects involve building quantum algorithms such as Grover’s search algorithm, Shor’s integer factorisation algorithm, etc. Please join our session on Thursday to learn more about all the interesting projects that are on offer.
