## Introduction

Quantum computing is an emerging technology that has the potential to change the world as we know it. Many businesses are already taking advantage of quantum computing to improve their operations. But what is quantum computing, and what does it mean for businesses? In this blog post, we will discuss quantum computing in greater detail and explore some of the business use cases that are already being developed. We will also answer the question: why should you learn about quantum computing today?

## What is quantum computing and how does it work

Quantum computers can solve problems much faster than classical computers. To understand why consider a maze with two different paths. A classical computer would have to try one path at a time until it found its way out of the maze. But a quantum computer can try all paths at the same time. Also, note that an 8-bit classical computer can only store one number from 0 to 255 whereas an 8-qubit quantum computer can hold every single number from 0 to 255 simultaneously.

#### Quantum Mechanics

How is that possible? The answer relies on quantum mechanics. Quantum computing harnesses the features of quantum mechanics to perform calculations faster than classical or traditional computers. Quantum computers work by taking advantage of quantum bits or qubits. This allows quantum computers to explore many different solutions to a problem at the same time, which explains why they are so powerful. While a classical computing binary unit, a bit, can hold either 0 or 1, a quantum bit, a qubit, possesses the ability to represent 0 or 1 as well as both values simultaneously, or, said differently, the quantum bit can be in a state of superposition.

### Superposition

What superposition can be thought of is a “complex linear combination.” Here, we mean “complex” not in the sense of “complicated” but in the sense of a real plus an imaginary number, while “linear combination” means we add together different multiples of states. So a qubit is a bit that has a complex number called an amplitude attached to the possibility that it’s in state 0 and a different amplitude attached to the possibility that it’s in state 1. These amplitudes are closely related to probabilities, in that the further the outcome’s amplitude is from zero, the larger the chance of seeing that outcome; more precisely, the probability equals the distance squared. Yet, amplitudes are not probabilities. They follow a different set of rules. For example, if some contributions to the amplitude are positive and others are negative, then the contributions can interfere destructively and cancel each other out so that the amplitude is zero and the corresponding outcome is never observed. Likewise, they can interfere constructively and increase the likelihood of a given outcome.

The goal in devising an algorithm for a quantum computer is to choreograph a pattern of constructive and destructive interference so that for each wrong answer the contributions to its amplitude cancel each other out, whereas for the right answer the contributions reinforce each other. If, and only if, you can arrange that, you’ll see the right answer with a large probability when you look. The tricky part is to do this without knowing the answer in advance, and faster than you could do it with a classical computer. Thus, when quantum computers are in a state of superposition, meaning that they are simultaneously performing multiple calculations and exploring many different solutions to a problem at the same time.

#### Entanglement

Quantum entanglement is when two particles are generated in a way that their quantum states become undefined until measured. The act of measuring one particle determines the results of measuring the other, even if they're far apart from each other. This happens because the quantum state of each object is connected to the others - even when they're separated by a large distance. In simpler terms, each particle can't be described independently from its entangled partner or group.

Thus, entanglement can be thought of as a quantum phenomenon that occurs when two particles are so deeply linked that they share the same existence. Even if they're miles apart, anything that happens to one particle will instantly affect the other. This bizarre connection was first theorized in the 1930s but wasn't proven until the 1980s. Now, researchers are exploring the possibilities of using entanglement for quantum computing and cryptography.

## The benefits of quantum computing for businesses

### Standard benefits:

#### 1. Faster problem resolution

One of the primary benefits of quantum computing is that quantum computers can solve problems faster than classical computers. This is because quantum computers can explore many different solutions to a problem at the same time, while classical computers can only explore one solution at a time. Thus, quantum computers can solve problems that are too complex for classical computers.

#### 2. Explore different solutions at the same time

Quantum computers can explore many different solutions to a problem at the same time because they can take advantage of quantum bits or qubits. Remember, qubits can represent a 0, a 1, or any other quantum state, which means that quantum computers can explore many different solutions to a problem at the same time. This makes quantum computers very powerful when it comes to solving problems.

#### 3. Secure and reliable

Quantum computers are secure and reliable because they harness the features of quantum mechanics.

### Emotional benefits:

#### 1. Change the world as we know it

Quantum computing has the potential to change the world as we know it.

#### 2. The Future of Technology

Quantum computing represents the future of technology. Quantum computing is an emerging technology that has the potential to change the world as we know it.

## How quantum computers are being used today

The four most common uses for quantum computers are quantum simulation, quantum linear algebra for AI and machine learning (ML), quantum optimization and search, and quantum factorization. These use cases can be applied to many industries. In addition, there is potential for the technology to be used in other industries as well. Some of the most notable use cases include quantum computing in the pharmaceutical industry to help with research and development, in the chemicals industry to improve catalyst designs, in the automotive industry to improve manufacturing process-related costs and shorten cycle times, in the finance industry for portfolio and risk management, and in the logistics industry. Note that the pharmaceuticals, chemicals, automotive, and finance industries could see the greatest benefits from quantum computing technology in the near term. It has been estimated that the benefits for these industries range from $300 billion to $700 billion.

### Automotive

Quantum computing can benefit the automotive industry in several ways, including research and development, product design, supply chain management, production, and mobility and traffic management. The technology could be used to decrease manufacturing costs related to processes such as path planning in complex multi-robot processes (the path a robot follows to complete a task), welding, gluing, and painting. Even a 2% to 5% productivity gain would create $10 billion to $25 billion of value per year.

### Finance

Even though quantum computing is still in its early stages, there are already many potential applications for it in the finance industry. The most exciting potential uses for quantum computing are in portfolio and risk management. For example, by using quantum-optimized methods to focus on collateral, lenders could improve their offerings, possibly lowering interest rates and freeing up capital. While it is too soon to estimate the value potential of quantum computing–enhanced collateral management, the global lending market was at $6.9 trillion suggesting a significant potential impact from quantum optimization.

### Pharmaceuticals

Quantum computing has the potential to revolutionize drug research and development in the biopharmaceutical industry. On average, it takes more than $2 billion and ten years for a new drug to reach the market after discovery. Quantum computing could make R&D dramatically faster and more targeted by making target identification, drug design, and toxicity testing less dependent on trial and error. A shorter R&D timeline could get products to patients more quickly and efficiently.

### Chemicals

Across different industries, quantum computing can yield more efficient catalyst designs--potentially increasing productivity by 15%. Companies stand to save billions annually. Furthermore, eco-friendly feedstock could replace petrochemicals, and quantum computing-designed catalysts may enable the breakdown of carbon for CO2 usage; both would be notable achievements in sustainability.

## What the future of quantum computing holds for businesses

There are many different categories of quantum computing research. One category involves simulation or modeling the natural world, such as chemistry and physics; another focuses on mathematical problems with complex structures like algorithms for processing data that require stability over time (because they deal in financial information). A third area is machine learning - an application where you use computers to find patterns from large amounts of statistical inputs without being told exactly what's expected! There’s also some interesting work going into solving non-linear differential equation systems via search/optimization techniques--a feat which would be very difficult otherwise due to its complexity.

Quantum computing can help businesses save money because quantum computers are very efficient when it comes to processing data. Quantum computers are also secure and reliable because they harness the features of quantum mechanics.
