IBM: A Brief Overview and Its Journey into Quantum Computing

IBM, an acronym for International Business Machines Corporation, is a multinational technology company that has been a pioneer in computing for over a century. Established in 1911 as the Computing-Tabulating-Recording Company (CTR), it was renamed “International Business Machines” in 1924. IBM is known for its continual technological innovation, having developed the first commercial computer, the IBM 701, in 1952 and the first computer system family, the IBM System/360, in 1964.

IBM’s journey into quantum computing began in the early 2000s with the establishment of the Quantum Information and Computation group. This group was tasked with exploring the potential of quantum computing, a field that leverages the principles of quantum mechanics to process information. Quantum computers use quantum bits, or qubits, which, unlike classical bits that can be either a 0 or a 1, can be both simultaneously thanks to a property called superposition. This allows quantum computers to process vast amounts of data simultaneously, making them potentially far more powerful than classical computers.

In 2016, IBM made a significant stride in quantum computing by launching the IBM Quantum Experience, the world’s first cloud-based quantum computing platform. This platform allowed researchers and the general public to experiment with IBM’s quantum processor. The Quantum Experience was a significant milestone in making quantum computing accessible to a broader audience and fostering a community of users and developers around this nascent technology.

In 2017, IBM announced the development of IBM Q, an initiative to build commercially available universal quantum computers for business and science.

As quantum computing technology evolves, IBM Quantum is poised to remain at the forefront of this exciting field.

Understanding Quantum Computing: The Basics

Quantum computing is a rapidly evolving field that leverages the principles of quantum mechanics to process information. Unlike classical computers, which use bits as their smallest units of information, quantum computers use quantum bits, or qubits. A classical bit can be in one of two states: 0 or 1. However, a qubit can be in a state of 0, 1, or both at the same time, a phenomenon known as superposition (Nielsen and Chuang, 2010). This ability to hold multiple states simultaneously allows quantum computers to process a vast number of computations at once, potentially solving complex problems much faster than classical computers.

The principle of superposition is closely tied to another quantum mechanical property: entanglement. Entanglement occurs when pairs or groups of particles interact in ways such that the state of one particle cannot be described independently of the state of the other particles, even when the particles are separated by large distances (Einstein et al., 1935). This interconnectedness allows for complex computations to be performed, further enhancing the computational power of quantum computers.

Quantum gates, the basic building blocks of quantum circuits, manipulate the states of qubits. They are the quantum equivalent of classical logic gates but with an important difference: quantum gates are reversible. This means that they can transform quantum states in a way that the original state can be recovered (Nielsen and Chuang, 2010). This reversibility is a fundamental requirement for quantum computing, as it preserves the superposition and entanglement of qubits.

Quantum error correction is another crucial aspect of quantum computing. Due to the delicate nature of quantum states, they are susceptible to errors from environmental noise and computational processes. Quantum error correction codes are designed to detect and correct these errors without disturbing the quantum state (Shor, 1995). This is a challenging task, as measuring a quantum state directly would cause it to collapse to a definite state, destroying the superposition or entanglement.

Despite the potential of quantum computing, there are significant challenges to its practical implementation. Quantum systems are extremely sensitive to environmental disturbances, and maintaining the coherence of qubits over time is a major hurdle (Preskill, 2018). Additionally, scaling up quantum systems to a large number of qubits while maintaining their quantum properties is a complex task.

IBM’s Quantum Products

IBM’s Quantum Products, namely Qiskit and IBM Q, are at the forefront of the quantum computing revolution. Qiskit is an open-source quantum computing software development framework that enables developers to create quantum computing programs and run them on quantum computers and simulators. It provides tools for creating and manipulating quantum programs and running them on prototype quantum devices on IBM Q Experience or on simulators on a local computer. It follows the circuit model for quantum computing, where quantum computations are broken down into a series of quantum gates (Haner et al., 2016).

IBM Q, on the other hand, is a series of quantum computers and services provided by IBM. It is a part of IBM’s commercial quantum computing program that aims to engage with businesses, academic institutions, and research labs to advance practical applications for quantum computing. IBM Q systems are designed to tackle problems that are currently seen as too complex and exponential in nature for classical systems to handle (Sutor, 2019).

The Qiskit framework is divided into four foundational elements: Terra, Aer, Ignis, and Aqua. Terra, the ‘earth’ element, provides the foundational building blocks for quantum computation, like quantum circuits. Aer, the ‘air’ element, provides high-performance quantum computing simulators with realistic noise models. Ignis, the ‘fire’ element, offers tools for characterizing errors and optimizing quantum computations. Lastly, Aqua, the ‘water’ element, provides higher-level quantum algorithms and applications that build upon Terra and Aer (Qiskit, 2019).

IBM Q, in contrast, offers a range of quantum systems with varying numbers of qubits, the basic unit of quantum information. These include the IBM Q System One, the world’s first integrated universal quantum computing system designed for scientific and commercial use. It is a 20-qubit system that combines into a single package the quantum and classical computing parts it takes to use a quantum computer for research and business applications (IBM, 2019).

IBM’s Quantum Products, Qiskit and IBM Q, are pioneering tools in the field of quantum computing. They offer a platform for the development and execution of quantum computing programs, and are designed to tackle complex problems that are currently beyond the reach of classical computing systems. Despite the challenges, the potential of these tools to revolutionize computing makes them an exciting area of research and development.

The Power of Quantum Chips

The company’s chip, the IBM Quantum Eagle, boasts 127 qubits, a significant increase from the 65 qubits of its predecessor, the IBM Quantum Hummingbird (IBM, 2021). This qubit increase allows the Quantum Eagle to perform more complex calculations and process larger amounts of data. However, it’s not just about the number of qubits. The quality of the qubits, their connectivity, and the error rates are also crucial factors in the performance of a quantum computer. Their very latest chip has 1,121 qubits and the company is busy executing on its extensive roadmap to get to a massive number of useable qubits.

The fabrication of IBM’s quantum chips involves a complex process that requires extreme precision. The chips are made from superconducting materials, which can carry an electric current without resistance when cooled to extremely low temperatures. The qubits are then created by placing tiny loops of these superconducting materials onto the chip. These loops act as tiny circuits that can carry a quantum state (Devoret & Schoelkopf, 2013).

IBM Quantum Research

It’s not just about the number of qubits. The quality of the qubits, often measured in terms of coherence time, is equally important. IBM has been able to achieve coherence times of over 100 microseconds, which is among the highest reported in the industry.

In addition to hardware, IBM Quantum Research is also pioneering advancements in quantum software and algorithms. Quantum algorithms, such as Shor’s algorithm for factoring large numbers and Grover’s algorithm for searching unsorted databases, have the potential to solve problems that are currently intractable for classical computers (Shor, 1997; Grover, 1996). IBM has developed a quantum computing platform, IBM Q Experience, which allows users to run experiments on IBM’s quantum processors via the cloud. This platform has been used by researchers around the world to conduct groundbreaking research in quantum computing.

IBM Quantum Research is also committed to fostering a global quantum community. Through the IBM Q Network, IBM collaborates with Fortune 500 companies, academic institutions, research labs, and startups to accelerate the development of quantum computing. IBM also offers educational resources, such as the Qiskit textbook, to help train the next generation of quantum scientists and engineers.

IBM’s pioneering work in quantum research is not without challenges. Quantum computers are extremely sensitive to environmental noise, which can cause errors in calculations. This is a major hurdle that needs to be overcome to realize the full potential of quantum computing. IBM is actively researching ways to mitigate these errors, such as through the use of quantum error correction codes (Preskill, 1998).

The Impact of IBM Quantum on Various Industries

This problem is computationally intensive due to the exponential growth of potential portfolios with the number of assets. Quantum computers, with their ability to process vast amounts of data simultaneously, can potentially solve this problem more efficiently than classical computers. Similarly, quantum computing can improve risk analysis and fraud detection by quickly analyzing large datasets to identify patterns and anomalies.

In the healthcare industry, quantum computing can revolutionize drug discovery and genomics. Drug discovery involves searching a vast space of potential compounds to find those that can bind to a target protein and alter its activity. This search can be significantly accelerated using quantum computers. Similarly, genomics involves analyzing large amounts of genetic data to identify variations associated with diseases. Quantum computers can potentially analyze this data more quickly and accurately than classical computers, leading to more personalized and effective treatments.

In the energy industry, quantum computing can enhance materials science and optimization problems. Materials science involves predicting the properties of materials based on their atomic structure. This prediction is computationally intensive due to the need to solve the Schrödinger equation, which describes the behavior of electrons in atoms. Quantum computers can potentially solve this equation more efficiently than classical computers, leading to the discovery of new materials with desirable properties. Similarly, optimization problems, such as scheduling and routing, are common in the energy industry and can be solved more efficiently using quantum computers.

In the logistics industry, quantum computing can improve supply chain optimization and vehicle routing. Supply chain optimization involves coordinating the flow of goods from suppliers to customers to minimize costs and maximize customer satisfaction. This problem is computationally intensive due to the large number of possible configurations. Quantum computers can potentially solve this problem more efficiently than classical computers. Similarly, vehicle routing involves determining the optimal routes for a fleet of vehicles to deliver goods or services. This problem can also be solved more efficiently using quantum computers.

IBM Quantum’s roadmap outlines the company’s ambitious plans for the future of quantum computing, with a focus on increasing the quantum volume of their machines, improving error rates, and developing software and applications for quantum computers.

Quantum volume, a metric often used by IBM (although pioneered by Honeywell), measures the computational power of a quantum computer. It takes into account both the number of quantum bits (qubits) and the complexity of the operations that can be performed on them. IBM Quantum aims to double the quantum volume of their machines every year, a goal they have achieved consistently since 2017. This exponential increase, reminiscent of Moore’s Law in classical computing, is a testament to the rapid advancements in quantum hardware.

However, increasing the quantum volume is not the only challenge. Quantum computers are prone to errors due to the fragile nature of quantum states. IBM Quantum is investing heavily in error correction techniques to improve the reliability of quantum computations. They are developing quantum error correction codes, such as the surface code, which can detect and correct errors without disturbing the quantum state. This is a crucial step towards building fault-tolerant quantum computers, which can perform long computations without errors accumulating and corrupting the results.
