Discover Quantum Computing: Your First Quantum Encounter

Embark on a journey into the fascinating world of quantum computing. This page will introduce you to the fundamental concepts that make quantum computing revolutionary and showcase why it's poised to transform various fields of science and technology.

Introduction to Complexity

Understanding Computational Complexity Before Quantum Computing

Before we dive into quantum computing, let's explore a crucial concept: computational complexity. As problems grow in size, their difficulty can increase dramatically, sometimes making them practically unsolvable for classical computers.

Experiment with our interactive widget below to see how complexity scales across three different problems:

  Generalized Sudoku

  Graph Isomorphism

  Number Factorization

Try solving each problem at different scales and observe how quickly they become challenging!

Introduction to Quantum Computing

The Power of Quantum Systems in Computing

Now that we've seen how quickly classical problems can become intractable, let's explore a paradigm that approaches computation differently: quantum computing.

Quantum computers harness the unique properties of quantum systems to process information in ways that classical computers cannot. One of the most fundamental quantum phenomena is interference, which we can observe even with something as familiar as light.

Our next interactive widget demonstrates a simple yet profound quantum optical setup known as a Mach-Zehnder interferometer. By adjusting the phase in one arm of the interferometer, you can observe how quantum interference patterns change.

Try our interactive Mach-Zehnder interferometer and see quantum interference in action!
On this widget, you can see a representation of a basic optical set-up composed with multiple components build on a typical optical table. The green box on the top left is a pulsed laser. Inside the table , a single photon source emits a single photon deterministically after each laser pulse. On the table multiple elements, mirrors, beamsplitters, phaseshifters, and single photon detectors. You can interact with each element with right click or change the view (see the wheel on the top right giving you more controls).

Quantum Concepts

Understanding the Foundations of Quantum Computing

What you observed in the interferometer shows a surprising truth that the light traveled through both paths simultaneously, revealing three key concepts of quantum computing. These principles form the foundation of quantum computing, allowing quantum computers to perform certain calculations exponentially faster than classical computers.

Superposition

The ability of a quantum system to exist in multiple states simultaneously.

Interference

The interaction between these superposed states, which can lead to amplification or cancellation of probabilities.

Measurement

The act of observing a quantum system, which causes it to "collapse" into a definite state.
