# What Is Quantum Computing? Definition, Industry Trends & Benefits Explained

We announced the alpha release of the Circuit Knitting Toolbox and Quantum Serverless this year, with a full release scheduled for 2025. You can check out the Circuit Knitting Toolbox and Quantum Serverless code repos here and here, respectively. Ever since we first put a quantum computer on the cloud back in 2016, we’ve been developing industry-leading hardware, software, and services for our users in order to prepare them for the next wave in computing. But as we’ve been following along our development roadmap, we realized that this year, we’re no longer just preparing.

Intel’s Director of Quantum Hardware, Jim Clarke, provides an overview of quantum computing and discusses what’s required to achieve quantum practicality. Securing the world’s digital infrastructure for the era of quantum computing. Complex problems are problems with lots of variables interacting in complicated ways. Modeling the behavior of individual atoms in a molecule is a complex problem, because of all the different electrons interacting with one another. Sorting out the ideal routes for a few hundred tankers in a global shipping network is complex too.

This interference is the probability of qubits collapsing one way or another. Because of the possibility of interference, quantum computers work to reduce it and ensure accurate results. To understand quantum computing and how it works, you first need to understand qubits, superposition, entanglement and quantum interference.

Percentage of large companies planing to create initiatives around quantum computing by 2025, according to research by Gartner. Quantum computers could be used to improve the secure sharing of information. Another area where quantum computing is expected to help is the environment and keeping water clean with chemical sensors.

Today, IBM Quantum makes real quantum hardware — a tool scientists only began to imagine three decades ago — available to hundreds of thousands of developers. Our engineers deliver ever-more-powerful superconducting quantum processors at regular intervals, alongside crucial advances in software and quantum-classical orchestration. This work drives toward the quantum computing speed and capacity necessary to change the world. Though specific quantum threats to blockchain-based projects vary, the potential fallout could be severe. For example, about 25% of bitcoins (currently worth $173B+) are stored in such a way that they could be easily stolen by a quantum computer-equipped thief, according to an analysis from Deloitte. Another fear is that quantum computers could eventually become powerful enough to decrypt and interfere with transactions before they’re verified by other participants on the network, undermining the integrity of the decentralized system.

Google has been working on building a quantum computer for years and has spent billions of dollars. Compared to traditional computing done by a classical computer, a quantum computer should be able to store much more information and operate with more efficient algorithms. The quantum state can be disturbed instantly by vibrations or temperature changes. This can cause qubits to fall out of superposition and cause errors to appear in computing. It’s important that qubits be protected from such interference by, for instance, supercooled refridgerators, insulation, and vacuum chambers.

Google is spending billions of dollars to build its quantum computer by 2029. The company opened a campus in California called Google AI to help it meet this goal. Once developed, Google could launch a quantum computing service via the cloud. Classical computers today employ a stream of electrical impulses (1 and 0) in a binary manner to encode information in bits. Theoretically, linked qubits can “exploit the interference between their wave-like quantum states to perform calculations that might otherwise take millions of years.” Global businesses are readying themselves today for the era of quantum computing.

### Qubit

The state of the qubit, the quantum 0 or 1, is represented by the amount of energy stored in the artificial atom. This bizarre quality stems from a quantum concept called superposition, in which an object can exist in two or more states at once. The concept, were it to be applied to everyday life, would result in the paradox known as Schrödinger’s cat, in which a fictional cat is simultaneously alive and dead. In 2022, quantum computing hit a rough patch, with share prices plunging for the three publicly traded companies specializing in the potentially revolutionary technology. Startups seeking strength in numbers are banding together, a consolidation trend with eight mergers so far by the reckoning of Global Quantum Intelligence analysts.

For example, a qubit can represent the values 0 and 1 simultaneously, whereas classical bits can only be either a 0 or a 1. Still another type of qubit relies on electrons, or more specifically, an inherent quantum property of electrons known as spin. Spin describes the electron’s angular momentum and is sometimes likened to the twirling movement of a top, but it is also analogous to magnetism because, like a magnet, an electron’s spin can point either downward or upward, representing the values of 0 and 1. One of these is the superconducting qubit or transmon, which is already in use in some early-stage commercial quantum computer prototypes from IBM and Google. A transmon is a sort of artificial atom built from materials such as niobium and aluminum that, at low temperatures, can carry electrical current without resistance. These materials are patterned to form a small electrical circuit that behaves like an atom.

## Understanding Quantum Computing

With a team of qualified and cleared staff, QIS delivers a range of solutions from entropy quantum computing to quantum communications and sensing, backed by expertise in logistics, manufacturing, R&D and training. The company is exclusively focused on delivering tailored solutions for partners in various government departments and agencies. AI-enabled business has arrived, and the need for quantum computing is approaching quickly. IBM’s central message at Think 2023 was that it is delivering artificial intelligence business solutions today and is rapidly developing robust quantum safe technology and services for near term deployment. Quantum computers exploit this so-called wave-particle duality to work with imaginary and complex numbers, which you might recall from precalculus or calculus classes. This type of mathematics differs from the type that classical computers (everything from laptops to alarm systems) do well.

## Better together: Silicon qubits plus light add up to new quantum computing capability

They can be programmed to run quantum algorithms that make use of qubits’ special properties to speed up calculations. A single qubit can’t do much, but quantum mechanics has another trick up its sleeve. Through a delicate process called “entanglement,” it’s possible to set qubits up such that their individual probabilities are affected by the other qubits in the system. A quantum computer with 2 entangled qubits is a bit like tossing 2 coins at the same time, while they’re in the air every possible combination of heads and tails can be represented at once. The researchers can then apply a strong magnetic field to the dots to coax them to transfer their quantum information to particles of light, or photons, which act as messengers to carry the information to other quantum dots located nearby. This strategy has already been used to entangle superconducting qubits, and the Petta group showed that this approach also works for spin-based qubits.

Instead, it will be a slow process of improvement, spurred on by fresh ideas for what to do with the machines — and by clever coders developing new algorithms. “What’s really important right now is to build a quantum-skilled workforce,” he says. Machine-learning algorithms perform tasks such as image recognition by finding hidden structures and patterns in data, then creating mathematical models that allow the algorithm to recognize the same patterns in other data sets. Success typically involves vast numbers of parameters and voluminous amounts of training data. But with quantum versions of machine learning, the huge range of different states open to quantum particles means that the routines could require fewer parameters and much less training data. Similarly, Riverlane is making the daunting requirements for a useful quantum computer more manageable.

### What Can Quantum Computing Solve?

Governments around the world are investing heavily in quantum computing research initiatives, partly in an attempt to bolster national security. However, a powerful quantum computer could be used to much more efficiently analyze different catalyst combinations — another application of simulating chemical reactions — and help find a better way to create ammonia. AI that taps into quantum computing could advance tools like computer vision, pattern recognition, voice recognition, machine translation, and more.
