What is Quantum computing?
Quantum computing is a multidisciplinary field that comprises computer science and physics, and utilizes the principles of quantum mechanics to optimize complex systems, crack encryption codes and solve technological problems.
It is built on three (3) science aspects which are:
- Computer science: This is the study of automation, computation and information of computers and how it can be applied to human daily activities.
- Physics: Physics, derived from the Greek word Physikos, is an aspect of science that studies matter, its structure, and interaction between the constituents of the universe. It also studies interactions between microscopic and submicroscopic particles of nature.
- Quantum mechanics: This is a fundamental theory of physics that studies the behavior of atomic and subatomic particles in nature. Quantum mechanics is a foundation for quantum information, quantum field theory, quantum chemistry, and quantum computing.
To understand the concept of quantum computing, you must understand the principles of physics, computer science, and quantum mechanics and their applications in quantum computing.
What is Linear Algebra?
Linear algebra, also referred to as quantum computing math, is used to describe quantum operations and qubit states (states of quantum bits usually taken to have the value of 0 and 1 but can exist in the multidimensional state) and to predict a quantum computer’s response to a sequence of instructions.
What is a Quantum Computer?
A Quantum computer is a machine that utilizes the principles of quantum physics and quantum theory to store data and enhance computations. They store data in binary digits called qubits (quantum bits), processing information faster than classical computers.
The first quantum computer was built in 1998 by Neil Gershenfeld of the Massachusetts Institute of Technology (MIT), Mark Kubines of the University of California at Berkeley, and Isaac Chiangmai of the Los Alamos National Laboratory. They created the first quantum computer ( 2-qubit) that could process data and output a solution.
Quantum Computing as a Career Path
As a beginner in quantum computing, obtaining a graduate degree in advanced concepts of general science, physics, mathematics, and computer science is required. This will aid your understanding of the practical applications in quantum computing, qualify you for higher positions, and help you to solve advanced problems.
To become skilled in quantum computing, you must be knowledgeable in quantum mechanics courses, cryptography courses, machine learning courses, astronomy courses, and electrical engineering courses.
As we proceed in this article, we will discuss each of these courses and their roles in quantum computing.
What You Need to Make a Pathway in Quantum Computing
Quantum computing requires broad knowledge of the principles of science, math, and their applications. Job opportunities in quantum computing require a bachelor’s degree in mathematics, physics, and other science-based courses. Here’s the pathway to becoming a qualified quantum computing professional;
If you’re interested in choosing Quantum computing as a career path. Below are some courses you would study:
1. Quantum mechanics
In Quantum computing, principles of quantum mechanics are applied to finding solutions to technological problems. Quantum mechanics is a field of physics that involves the study of atoms, subatomic particles, and their behavior.
There are four types of quantum mechanics. They are:
- Quantization of physical properties: This concept defines the size and property of a physical quantity. It is a continuous process of mapping infinite values to a smaller set of finite values. Energy, light, matter, and angular momentum are quantized on the atomic level.
- Wave-particle duality: This is an aspect of quantum mechanics that studies how microscopic objects simultaneously possess characteristics of both particles and waves.
- Uncertainty principle: Also known as Heisenberg’s indeterminacy principle, formulated by Werner Heisenberg in 1927. The uncertainty principle states that the position and speed of a particle, such as a photon or neutron, cannot be known with perfect accuracy. The more a particle is restricted to a specific position, the less stable its speed and vice versa.
- Quantum entanglement: This phenomenon arises from the connection between particles. It occurs when a group of particles share spatial proximity and remain connected over long distances.
Quantum computing utilizes principles of physics to create new ways of computing. Since quantum mechanics is a field of physics, a deep knowledge and understanding of physics is required to operate quantum computers.
Quantum computing relies on fundamental aspects of mathematics such as linear algebra, complex numbers, and probability. All these contribute to the accurate functioning and operation of quantum computers as they help to describe quantum operations and qubit states and to predict a computer’s response to a sequence of instructions.
Quantum cryptography communication was set up to improve security and to protect critical information in the 5G era.
Quantum cryptography utilizes the naturally occurring properties of quantum mechanics. It applies it to quantum computing by encrypting data to safeguard it and transmit information so that it can’t be plagiarized.
5. Quantum programming
It is imperative to have a good knowledge of quantum programming languages to operate quantum computers. Quantum programming can be divided into two programming languages:
Imperative programming languages: This uses codes explicitly written to solve a software problem. In imperative programming, functions are coded in every step, and the code specifies how the problem can be solved.
Functional programming languages: Functional programming languages are based on mathematical functions and only support functional paradigms. Examples of functional programming languages are Lisp, Erlang, Haskell, Clojure, and Python.
Python is one of the most famous quantum programming languages. C++, Qiskit, Cirq, Quipper, Forest, and PyQuil are also programming languages used in quantum computing.
6. Electrical engineering
We all know that electricity powers quantum theory-based machines and devices! Hence, electrical engineers play a significant role in improving the overall performance of quantum computing systems by utilizing their expertise in circuit design, developing new strategies for optimizing qubit interactions, and minimizing noise.
