Quantum Algorithms: The Future of Quantum Computing – Predictions and Trends

Decoding Tomorrow: The Evolution and Impact of Quantum Algorithms

At QCentroid, a pioneering Quantum Computing Platform as a Service (PaaS) company, we are excited to make a deep dive into the future of quantum computing, particularly focusing on quantum algorithms.

In most cases, quantum algorithms represent a fundamental shift from classical computing algorithm designs.. Unlike traditional binary-based algorithms, quantum algorithms utilises two core principles from quantum mechanicsP the the superposition of quantum states and entanglement of quantum states, to process information at speeds that provably for certain algorithms, can be up to exponentially faster than classical computers.

Quantum algorithms can be segmented into three classes. The first class is that of near terms quantum algorithms that utilize quantum and classical computers to perform computations (recall that quantum computers are always controlled by classical computers). Often, these two classes are referred to as “variational quantum algorithms”. The second class is the one of quantum-inspired algorithms. These are classical algorithms that try to mimic, on  a classical computer, the way a quantum computer would make them work. While these algorithms cannot be exponentially faster than classical ones, they provide an alternative starting point to solve certain problems possibly more efficiently. Finally, the third class is that of fault-tolerant quantum algorithms such as Shor’s algorithms, Simon’s algorithm, Grover’s algorithm, etc.

Predictions: A Glimpse into the Quantum Future

Looking ahead, several trends and predictions stand out in the realm of quantum algorithms and where they can be useful.

  1. Quantum Machine Learning (QML): QML algorithms are poised to redefine data science, machine learning and artificial intelligence. By harnessing quantum algorithms of any of the three classes mentioned previously, one may hope to be able to analyze complex datasets more efficiently, leading to breakthroughs in fields like climate modeling, financial analysis, and more.
  2. Cryptography and Security: Quantum algorithms will transform cybersecurity. Quantum-safe encryption methods are being developed to counter the threat posed by quantum computing to current encryption standards. This shift is not just a necessity but an impending industry standard.
  3. Optimization Problems: From logistics to energy management, quantum algorithms of any of the three families discussed before may offer superior solutions to complex optimization problems. Real-time examples include optimizing supply chain routes or energy distribution in smart grids, enhancing efficiency and sustainability.

However, going from the classical way of designing algorithms to quantum algorithm design is not an easy step. Beyond educational tools and given tools such as the ones QCentroid offers one may make this journey as easy and pleasant as possible.

Overall, the e quantum computing landscape is evolving rapidly, with a few key trends shaping its future:

  • Increased Accessibility to cloud quantum computing is here to stay. Platforms like QCentroid are democratizing access to quantum computing, enabling researchers and businesses to experiment with quantum algorithms without needing their own proprietary quantum hardware.
  • Hybrid Quantum-Classical Systems (related to variational and quantum-inspired algorithms). The near future will see a blend of quantum and classical computing, where quantum algorithms tackle specific tasks within larger classical systems, optimizing performance and resource utilization.
  • Cross-industry Collaboration: Quantum computing is fostering unprecedented collaborations across sectors – academia, government, healthcare, finance, and more, all converging to explore the potential of quantum algorithms.

The ability to design and utilise  quantum algorithms will play a pivotal role in shaping the next generation of quantum technological advancements. At QCentroid, we are committed to being at the forefront of this journey, providing the tools and expertise needed to harness the power of quantum computing.

The future is quantum, and the possibilities are limitless. Join us at QCentroid as we explore the uncharted territories of quantum computing, paving the way for a smarter, faster, and more efficient tomorrow.

        The Quantum Edge: How Quantum Computing is Driving Innovation in Finance

        Quantum Computing: Redefining Cybersecurity in the Digital Age

        In the finance industry, the arrival of quantum computing marks a significant milestone [1]. This cutting-edge technology is not a buzzword, rathera potentially revolutionary force reshaping how financial institutions operate. From intricate financial modeling to portfolio optimization and risk analysis, quantum computing is setting a new standard for accuracy and speed. In this article, we explore how quantum computing is driving innovation in the finance sector, backed by compelling case studies and examples.

        Financial modeling is of fundamental importance  in financial analysis and financial decision making and has the potential to be profoundly impacted by quantum computing. In many situations, classical models struggle with the complexity and or volume of data in finance. However, quantum computers may be able to complex datasets and solve combinatorial problems or machine learning problems associated with them more efficiently.

        Revolutionizing Portfolio Optimization

        Portfolio optimization is another area where quantum computing is making its mark. The challenge in traditional methods lies in balancing the trade-off between risk and return, a task that grows exponentially complex with more assets. Quantum computers can process these complexities much faster.

        Risk analysis is crucial in finance, and quantum computing offers unprecedented advantages in this domain. Traditional risk assessment models often oversimplify real-world scenarios, or are too slow to implement, leading to less accurate predictions. Quantum computing, however, may be able to simulate complex financial systems and predict potential market shifts with greater precision. This is mostly seen via the famous Quantum Amplitude Estimation algorithm which can, essentially, perform Monte-Carlo simulation quadratically faster. A relevant use-case in point is that financial institutions may use quantum computing for credit risk analysis. This approach may enable them to better understand the potential risks, improving their strategy for loan approvals and interest rate setting.

        Quantum computing is more than just a technological advancement; it has the potential to be a paradigm shift in financial analysis and decision-making. By providing deeper insights and faster processing, it is enabling finance professionals to stay ahead of the curve. As we continue to witness its growing applications in financial modeling, portfolio optimization, and risk analysis, it is clear that quantum computing is not just shaping the future of finance—it is defining it.

        Connecting Quantum computing to Web3. A tech approach.

        No-code quantum algorithms execution with the QCentroid Platform

        In this article we’re going to go through the requirements, the challenges and the solutions adopted to connect the Ethereum blockchain to the QCentroid Quantum Solutions Platform.

        Due to the nature of blockchain ecosystems, accessing off-chain data from on-chain smart contracts is not natively possible. However, oracles like Chainlink provide this bridge between on-chain and off-chain data. Oracles enable smart contracts to retrieve data from the outside world.


        The QCentroid Platform is accessible through an authenticated REST API, just like almost any other platform out there.

        To access our platform from the blockchain, we decided to use ChainLink oracle platform.

        Due to the nature of quantum computing, the QCentroid platform works in an asynchronous mode, which means that the result of a computation request is not returned right away in the response. Instead, a Job Id is returned to be used later to check the job status and to obtain the result.

        This asynchronous behavior adds a layer of complexity to the whole workflow from the smart contract, through the oracle, to the Quantum Platform and back.

        But, before we enter in detail into this workflow, let’s see the architecture that we have deployed and all the components that we need.

        This diagram shows all the components involved:

        • The user’s smart contract
        • The QCentroid Quantum provider smart contract
        • ChainLink Oracle
        • A ChainLink node
        • The External Adapters
        • The QCentroid Platform
        • ChainLink keepers

        Depending on your application, you will not always need all these components. In our case, I would like to highlight four of these components and why we decided to deploy, run and operate them ourselves.

        The QCentroid provider smart contract simplifies the access to the oracle to the final users. A final user smart contract only needs a call to this provider contract and a callback function  instead of extending the Chainlink client contract and the use of LINK tokens, oracle address and job ids. This provider smart contract manages all this.

        If you need to use authentication to access an API you are going to need an External Adapter. This may already exist if you’re accessing a well known API, such as GitHub or Twitter, but if you are trying to connect to your own API or to a not so common API, you’ll have to build your own adapter.

        Becoming a ChainLink node operator is not a trivial task, it’s a job itself. In our case, our own ChainLink node is needed to control the access to the Platform API. As the credentials to access the API are managed at the External Adapter, now we need a mechanism to control the access to this external adapter. The way to do this in the ChainLink platform is through address whitelisting at node level. This is why we decided to run and operate our own ChainLink node to be able to manage the list of approved addresses.

        ChainLink Keepers provide decentralized and highly reliable smart contract automation. Due to the asynchronous nature of the QCentroid Quantum Platform we make use of ChainLink Keepers to poll the status of the ongoing jobs and fetch the result whenever it is ready.

        These four components may or may not be needed by your application, but now you know the role they play in the ecosystem and you can decide whether you need them or not. 

        For most of these components you’ll find tons of information and tutorials on how to build and deploy them. Here are the resources that we used at QCentroid to build our ecosystem.

        To start building our own External Adapter, we used the Chainlink NodeJS External Adapter Template by Thomas as a starting point. This adapter is written in NodeJS and allows you to run it locally, as a Docker service or serverless (using AWS Lambda for example).
        The API-specific values are configured as environment variables, so they are not hardcoded and they can be easily filled by your CI/CD workflow.

        Building and running your own ChainLink Node for development purposes is also a relatively simple task relying on the resources shared with us by ChainLink, like the ChainLink SmartContract Kit. There you’ll find step-by-step instructions on how to build and run a ChainLink node. Setting up the node for operational purposes is where things start to get complicated and would be subject for another article. 


        Now that we know what all these elements are, what they are for and how to build and run them, let’s have a look at a full workflow, from the initial request from a user’s smart contract to the reception of the solution from the Platform.

        This workflow shows the different components described earlier and how and when they are involved in the process and they’re role.

        It’s important to mention that our main objective when designing this architecture was to simplify as much as possible the work needed by our smart contract end users. The diagram clearly shows how few “arrows” are needed on the left and how our users only need to focus on their business. As the workflow moves to the right, we can see how the components involved in the architecture handle the tedious tasks such as authentication or polling for the results.

        For our end users, using Quantum computing from a smart contract is as easy as: “here is my data, here is your result”.

        With this article, we wanted to show our specific use case of a hybrid on-chain/off-chain architecture and how we’ve approached the connection between these two worlds using ChainLink’s breakthrough oracle technology.
