The quantum leap in hosting: how quantum computing is reshaping the future of web servers.

In 2023, IBM’s Condor broke a record for the number of superconducting qubits, packing 1,121 under the hood. Early 2025 also saw Amazon unveil its Ocelot, whose qubits naturally suppress errors, a long-standing problem in quantum computing.

While headlines of this type have been constant in tech news for more than a decade, the last few years have actually felt like we’re heading toward general-purpose quantum computers.

One area where we might see these sooner rather than later is web hosting. In fact, the National Institute of Standards and Technology (NIST) already set a deadline by which legacy encryption methods will be completely disallowed.

This is one of the changes pushing servers to either adopt quantum computing or protect against it. And although a timeline is difficult to set, Cybernews researchers and I dug into the subject to see how these changes might affect the very backbone of the internet in the future.

Classical computing 101

Before we delve into quantum computing, we should first take a quick look at traditional computers and explain how they work. This will help us understand whether classical machines will be replaced by ones that rely on quantum phenomena like superposition and entanglement.

At the core of each classical computer is a processor that relies on bits. These are the basic units of traditional computing, and they operate on the binary code principle. This essentially means they can either be off (0) or on (1).

These binary digits then combine to form binary code, strings of which can be used to represent numbers, text, images, videos, and sound. Thus, every calculation, application, and website stems from this principle.

Let’s take a photo as an example. Your phone’s (or computer’s) processor essentially assigns combinations of 0 and 1 to every pixel of your image. If you’ve just sent a photo to your friend, their device’s processor decodes the zeros and ones to display the image.

With processors (CPUs) capable of simultaneously handling hundreds of billions of bits per second, we’ve come a long way from the basics. In fact, modern CPUs can handle these tasks nearly instantly, so you never get to see behind the scenes.

Limits of classical computers

While binary processors have been at the heart of every computer, smartphone, and data center for decades, they do have limitations. Due to the nature of binary, these processors quickly become inefficient when solving problems that grow exponentially in complexity.

Let’s say you were trying to predict weather patterns on a global scale. While this doesn’t feel like that difficult of an issue nowadays, it’s actually a problem with a vast number of possibilities.

A classical computer would start off fine, and you’d have accurate results for a while. However, as the number of calculations increases, the problem would quickly outgrow the processing capabilities of a traditional binary processor.

So, while bit-based processing is more than fine for scrolling Instagram, watching YouTube videos, or gaming, accurate simulations aren’t something these processors can handle. After all, many of nature’s systems operate on the principles of quantum mechanics. Thus, they also require a quantum computer to simulate.

What is quantum computing, and how does it work?

At its core, quantum computing involves utilizing quantum mechanics to process information. Unlike traditional computers, which rely on bits that can only be a 0 or a 1, quantum computers use qubits.

These fundamental units introduce one of the core principles of quantum mechanics into computing. A qubit can exist as a 0, a 1, or both simultaneously, a phenomenon known as superposition. This allows the qubit to hold exponentially more information than a bit.

While it’s difficult to imagine how something can be turned on and off at the same time, there is one analogy that might help. You can think of a qubit as a spinning coin that can be seen from multiple angles. While spinning, it’s not just heads or tails (0 or 1), but a blend of both possibilities at once.

This allows quantum computers to simultaneously tackle multiple calculations instead of going one by one. The result is a massive leap in computing power that can be harnessed in climate simulations, drug discovery, financial modeling, artificial intelligence, and cryptography.

Quantum computing in web servers

With quantum computing still in its developmental stage, you won’t find any web servers using dedicated quantum hardware just yet. However, some providers have already started preparing for the inevitable downfall of legacy encryption methods.

This has a lot more to do with cybersecurity than qubit-based web hosting, but it goes on to show that companies are already preparing for the quantum leap. For now, this boils down to adopting NIST-standardized post-quantum cryptography (PQC) algorithms.

In March 2025, Cloudflare rolled out an update that made one-third of its servers more resistant to quantum computing-powered break-ins. With Cloudflare powering around 20% of the world’s websites, a large chunk of the web has already received quantum-resistant encryption.

At the same time, one of the top hosting providers, Liquid Web, also introduced encrypted cross-region private networking for all its bare metal hosting plans. This eliminates the need for third-party VPNs, ensures higher speeds and lower latencies, and makes adhering to standards like HIPAA more straightforward.

Pair that with Liquid Web’s use of the GnuPG (GPG) encryption standard, and you get highly secure hosting for anything from email and WordPress to e-commerce and dedicated servers.

Potential benefits of quantum computing for web servers

While quantum computers won’t be powering our websites and taking over our day-to-day operations anytime soon, the potential benefits of quantum computing in web hosting are certainly worth discussing. In the realm of servers, we’re looking at the following:

• Stronger website encryption. One of our current encryption standards, RSA-2048, would take modern computers billions of years to break using brute-force methods. However, a theoretical 20-million-qubit quantum computer would be able to crack it in 8 hours. As a result, websites are already adopting PQC, which aims to make servers resistant to quantum computing attacks.
• Optimized network infrastructure. Quantum computing could also improve how hosting providers manage visitors. Sudden network traffic surges would no longer be an issue with quantum-powered server load balancing, resource allocation, and traffic routing. This would also reduce both operational costs and energy waste.
• More stable websites. Sites are known to slow down when a large number of users flood in. In fact, that’s essentially what DDoS attacks rely on and how attackers brought down Amazon Web Services (AWS) in 2020. However, quantum-assisted hosting would render such attacks useless, with sites becoming far more stable during peak hours.
• Accelerated data processing and AI integration. Being able to handle multiple complex calculations simultaneously allows quantum computers to excel at processing vast amounts of data. And with AI-powered systems relying on fast data processing, tools like chatbots and fraud detection engines would be able to operate in real time.
• Real-time vulnerability analysis. Another web hosting aspect that could run in real time with the help of quantum computing is vulnerability analysis. A qubit-powered system would be able to scan server logs, traffic, and system data instantly, allowing it to detect anomalies and prevent them from turning into breaches.
• Shorter development cycles. Finally, quantum computers could also improve our existing software development life cycle (SDLC). This would essentially allow developers to simulate, test, and debug code much more efficiently, as quantum-based hardware could lead to quicker error identification, performance optimization, and rollouts of updates.

Challenges of quantum computing

It’s worth noting that, apart from PQC, which is already being adopted, most of the benefits mentioned above are purely speculative. And the reason why it’s all still theoretical is the vast number of challenges that come with the implementation of quantum computing.

For instance, superposition isn’t the only principle of quantum mechanics that these machines bring. There’s also entanglement to worry about here, which refers to the property of qubits to link to each other. This makes the state of one instantly affect the other, which adds a lot of complexity to the mix. It also makes error correction quite challenging.

Stability is another big hurdle. Qubits are known for being fragile, with even the smallest changes in temperature and vibrations capable of disrupting them. That’s precisely why they and, thus, quantum computers, require extremely low temperatures near absolute zero.

Last but not least is the cost of quantum machines. The notoriously fragile qubits require extreme engineering in terms of infrastructure and specialized materials that could reach and maintain low enough temperatures. And that’s not even going into the high cost of research and development, as quantum computing is still in its nascent stage.

Until we tackle these challenges, our current web hosting solutions will do just fine. And if secure hosting is what you’re after, Liquid Web already offers everything you need to keep your site safe. That includes two-factor authentication, network firewalls, TLS encryption protocols, and auto-renewing SSL certificates, among other security features.

Our take: what does the future hold?

Although quantum computing is still in its early stages of development, hosting providers have already begun to up their game in anticipation of what the future will inevitably bring. For now, this has to do with PQC, with millions of sites already receiving quantum-resistant encryption.

However, by the looks of it, we won’t be seeing any other benefits anytime soon, as quantum hardware won’t replace traditional computing in web servers in the foreseeable future. Instead, it’ll likely first appear as a specialized service that handles computationally demanding tasks, such as large-scale data analysis, network traffic optimization, and even SDLC improvements.

Until that day comes, our regular online activities will be handled by classical computing machines. Meanwhile, leading hosting providers like Liquid Web will find other ways to secure servers against unauthorized access with firewalls, monitoring, and vulnerability scans.
