### Getting the workforce quantum-ready

With our quantum developer certification, companies and research institutions will find a clear path to get their workforce quantum-ready. The certificate will help those hiring for classical programming and non-programming roles recognize holders of this certification as forward-thinking individuals willing to skill up for the future of the computing workforce.

The IBM Quantum Developer Certification is a 60-question certification exam offered on the Pearson VUE platform. Those who pass the exam will have demonstrated experience using Qiskit to create and execute quantum computing programs on IBM quantum computers and simulators, and the ability to perform these tasks with little to no assistance from product documentation, support, or peers.

### What to expect from the exam

We figure that plenty of Qiskitters will be looking to take the certification exam, so we’ve put together a sneak peak of the exam’s structure, what’s going to be on it, and how to study for it. The test is going to be a 60-question exam, in English, offered on the Pearson VUE platform. The goal of the test is to certify that those who pass it can define, execute, and visualize quantum circuits using Qiskit, implement single and multi-qubit gates and understand their effects on quantum circuits, and leverage the fundamental features of Qiskit in order to write quantum programs.

### Backing up a little: History repeating itself

Massive hardware, limited bits, software infancy

Quantum computers make direct use of quantum-mechanical phenomena, such as superposition, interference and entanglement, to perform operations on data.

Feasible on **classical** computers

Feasible on **quantum** computers

Solutions to problems

### Why use a quantum computer?

Some problems may be solved exponentially faster

“Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy.”

### Simulating nature

complex chemical reactions, for example

**Dr. Richard Feynman, 1981**

“If you start factoring 10-digit numbers then it’s going to start getting scary”

### Breaking RSA crypto

someday maybe, using Shor's algorithm, formulated in 1994

**Dr. Peter Shor, 2013**

“Programming a quantum computer is particularly interesting since there are multiple things happening in the same hardware simultaneously. One needs to think like both a theoretical physicist and a computer scientist.”

### Quickly searching unsorted data

using Grover's algorithm

**Dr. Lov Grover, 2002**

### NISQ* era quantum computing domains

### Machine Learning

### Optimization

### Chemistry

### Finance

**Noisy Intermediate Scale Quantum computers*

## Axioms of Quantum Mechanics

### featuring grumpy cat (or is it grumpy **ket**)?

## My microscopic cat is often grumpy

### sometimes he is actually happy

### but I've never observed him in-between those states

## Axiom 1: Superposition principle

### my cat can be in any combination of grumpy and happy

## Representing quantum states

### geometrically, ket notation, and vectors

## Axiom 2: Unitary evolution

### gates modeled as matrices

**X**

NOT gate (Pauli/X, bit-flip)

## Hadamard gate

### great for putting cats in equal superpositions

**H**

Hadamard gate

## Axiom 3: Measurement

### probability is amplitude squared

When observed there is a:

probability of being grumpy

probability of being happy

## Multiple cats

### Composite quantum states

## Multiple cats

### Composite quantum states

## Superpositions, evolution & measurement

### putting the three axioms together

*quantum gates*

*quantum gates*

*measure*

with 1/2 probability

with 1/6 probability

with 1/3 probability

## Quantum entanglement

### spooky actions at a distance
