#1about 3 minutes

Understanding quantum states and superposition

Quantum systems have discrete energy levels, and a qubit can exist in a combination of these states, known as superposition, until it is measured.

#2about 3 minutes

Visualizing qubits and quantum gates as matrices

A qubit's state can be represented as a vector on the Bloch sphere, and quantum gates are matrices that perform operations like rotations or flips.

#3about 5 minutes

A live demo building a basic quantum circuit

Learn how to use frameworks like IBM's Qiskit to build a circuit, apply gates, entangle qubits, and measure the probabilistic results on a simulator.

#4about 2 minutes

Understanding advanced quantum algorithms and subroutines

Subroutines like the Quantum Fourier Transform and phase estimation are building blocks for powerful algorithms like Shor's algorithm for factoring.

#5about 2 minutes

An overview of different quantum hardware types
