What is Quantum Volume and Why Does It Matter?
What is meant by quantum volume, and why should anyone care? In the fast-moving world of quantum computing, quantum volume has emerged as perhaps the most critical yardstick. It tells us something essential about how well a quantum computer can solve hard problems. Getting a grip on quantum volume can have a substantial payoff for your business, as the world starts to pay more attention to the nascent field of quantum technologies.
Understanding Quantum Volume
The largest number that a quantum computer can effectively use to perform computations is known as quantum volume. This metric has several performance factors that contribute to it, among them:
- Count of quantum bits
- Error Rates
- The number of non-parallel operations in a quantum circuit. The fewer the operations, the “shallower” the circuit; the more, the “deeper” it is.
When we take these factors into account, quantum volume yields a much clearer picture than just counting qubits. A prime comparison is with IBM’s 53-qubit Eagle processor. In this case, Eagle has a QV of 64. Even more striking, by this measure, a lesser-known processor from 2019, with only 20 qubits, is calculated to have a QV of 32. To be clear, this isn’t saying that having fewer qubits means you’re surpassing another processor with more qubits; in fact, in terms of both power and an accessible computational basis, 20 qbits are likely to compatible with and.
Furthermore, the complexity of problems that a quantum computer can solve corresponds to its quantum volume. Solving large, difficult problems is what we want a quantum computer for in the first place, with potential applications in nearly every field of science and engineering, including cryptography, artificial intelligence, and optimization.
What is Quantum Volume and Why Does It Matter for Businesses?
We have set up what the quantum volume is; now, we must explore the why behind it. Why does it matter, especially to businesses? The adoption of quantum technologies by companies is increasing. Therefore, understanding not just the way but also the various combination forms of quantum volume can lead to better investment pathways and research judgment calls.
For example, companies can assess prospective alliances with firms in the quantum computing space. By using quantum volume as a metric, entities can better determine which of these paralleled machines are best equipped to handle their computational workloads. Domains like finance, the life sciences, and logistics have already begun reaping benefits from their nascent work in this area. In a 2022 business survey, 43% of executives said quantum computing could have a substantial impact on their operations, with benefits beginning to appear in the next five years.
Furthermore, firms that comprehend the ramifications of quantum volume can devise superior strategies. It enlightens them regarding the timeline for deploying and integrating it into their operations. A clear comprehension of quantum volume enables companies to:
- Pinpoint appropriate demonstrations of the software’s use.
- Refine efforts in research and development
- Evaluate the danger against the profit in quantum investments.
Examples of Quantum Volume Impact
Numerous firms are already delving into quantum volume to boost their products and services. Take, for instance, Google’s Sycamore processor. Its infamous quantum supremacy experiment saw Sycamore achieve a quantum volume of 16. In that landmark achievement, Google used Sycamore to complete a task in 200 seconds that would have taken the best classical computers thousands of years.
Additionally, IBM drives quantum volume to new heights. This promises to deliver unprecedented capabilities for large-scale, noisy quantum systems—and to do so, in part, by improving coherence times and error correction. The company intends to achieve a 1,000 quantum volume in 2025 with two of its processors, the Eagle and the Condor.
Advancements in quantum technology make clear how quantum volume serves as a key gauge of progress. If you take a step back and look at all the recent reports from the different major players (IBM, Google, Rigetti, etc.) in the field of quantum volume, all the talk seems somewhat glorified. Sure, physics is hard, and making these types of machines work is harder still. But actual reports of suitable qubits being used to do suitable things seem few and far between.
The Future of Quantum Computing and Its Business Implications
Looking ahead, the task of business quantum volume grows more significant. Benefits that this computational power can confer over the long term are beginning to dawn across many different industries.
Take pharmaceuticals, for instance: They could enjoy an upheaval in the processes by which they discover new drugs, because quantum computers can do something that classical computers can’t do; namely, they can simulate and analyze the way molecules interact with one another under different conditions much faster than classical methods (or even human beings) can. And in these kinds of simulations, speed is everything.
In addition, the worldwide quantum computing market is expected to blossom into a $65 billion industry by the year 2030. So, preparing for its effects on business seems prudent. Also, putting money into quantum volume might pay off handsomely down the road.
To sum it all up, what is quantum volume, and why is it essential? Understanding this concept is critical for firms that want to maintain a forward edge in a technology-driven marketplace. Businesses that base their insight on quantum volume will be in a prime position to truly tap into the power of quantum computing, which—by our reckoning, at least—will be good for improved efficiency, innovation, and a competitive edge in the not-so-distant future.
