The Significance of Google's Quantum Leap in Technology

Understanding Quantum Computing
With the recent announcement from Google regarding advancements in quantum computing, many are left wondering what this entails for the future. On October 23, 2019, Google declared that it had achieved "Quantum Supremacy." For those unfamiliar with quantum computing, let’s break it down into simpler terms.
If you're already well-versed in the subject, feel free to skip ahead.
What is Quantum Computing?
Quantum computing represents a significant leap in processing power, with technology evolving rapidly. To grasp quantum computing, it's crucial to understand classical computing first. Traditional computers operate like advanced calculators, utilizing bits that represent either a 0 or a 1. These bits serve as the foundation for decision-making based on user inputs through specified instructions.
In contrast, quantum computers utilize quantum bits, or qubits. These qubits can exist as a 1, a 0, or both simultaneously. This capability allows for the storage of vast amounts of information with significantly less energy, making quantum computers potentially millions of times faster than today’s most advanced supercomputers.
The Buzz Around Quantum Supremacy
So, what exactly is this "Quantum Supremacy" news? Google’s quantum processor, known as Sycamore, solved a particular problem in just 200 seconds. This groundbreaking achievement was published in the scientific journal Nature, solidifying Google’s claim to be the first to reach "Quantum Supremacy."
To illustrate, Google compared the speed of Sycamore with IBM's fastest classical computer, which would take over 10,000 years to solve the same problem. Interestingly, IBM's supercomputer, named Summit, stretches across the length of two basketball courts! IBM researchers have countered Google's claims, arguing that it’s not fair to focus on a single problem with limited practical applications, asserting that their machine could solve it in 2.5 days instead of the exaggerated 10,000 years. Robert Sutor, IBM’s executive overseeing quantum computing strategy, remarked, “Quantum supremacy? We don’t use that term at all.”
Why Does This Matter?
At first glance, quantum computing may seem esoteric and complex. However, its real-world applications could be transformative. Unlike a rocket launch or a nuclear explosion, the impact of quantum computing is more nuanced and could reshape various industries. As Scott Aaronson noted, the potential applications in fields ranging from drug discovery to financial modeling are virtually limitless.
Drug Discovery: A Case Study
The process of discovering new drugs has always been intricate and time-consuming. Chemists typically need to evaluate countless molecular combinations to develop effective medications. This process can be both expensive and lengthy, with many failures stemming from trial and error.
Quantum computers could streamline this process by mapping trillions of combinations, significantly reducing both the time and cost of drug development.
The Flip Side: Security Concerns
However, quantum computing is not without its challenges. It also raises significant cybersecurity concerns. In a recent episode of the podcast Recode, Duhaime-Ross discussed how quantum computing could potentially compromise the internet by breaking widely used encryption methods, such as RSA encryption. “Currently, that’s how we secure a lot of information online. But with a powerful quantum computer, the time it takes to break down large numbers becomes drastically shorter, jeopardizing the encryption keys we rely on to keep data secure,” Duhaime-Ross explained.
As quantum technology advances, the risk of breaches in encryption algorithms could threaten critical activities like banking and online transactions, making cybersecurity an urgent priority.
The Future of Quantum Computing
Will quantum computing soon be accessible to the general public? Unfortunately, the answer is no. While IBM has introduced a 53-qubit quantum computer to select customers, the costs remain astronomical—over $10,000 for just one qubit.
Although it may take years or even decades for quantum computing to become mainstream, the rapid progress made by companies like IBM, Google, and Microsoft indicates a bright future ahead.
