You do not need to have a PhD to read and understand this book. There is a strong limitation on the joy of quantum computing: Once a qubit is measured, all information about the potential superposition it was in is lost. At the same time, articles with a less technical background talk about the potential consequences of quantum computing, ranging from breaking most of current encryption techniques to a fix for all diseases to complete general AI. Quantum Computing for Developers will make sure you’re prepared to start programming when quantum supercomputing becomes a practical reality for production systems. In 2015, he cofounded Gluon, which allows enterprises to create mobile Java client applications leveraging existing back-end infrastructure. The qubit will be either 0 or 1. We didn't discuss any of the known quantum algorithms, including Shor's algorithm that allows factoring integers into primes. With this book, I want to introduce the potential and relevance of Quantum Computing to Java Developers. In quantum computing, we have equivalents for bits and gates. As an end developer though, your code does not depend on whether you will be using CPU power or GPU power. Cambridge, Mass.-based Biogen is another notable company exploring quantum computing’s capacity for drug development. pBook + eBook He is the colead of OpenJFX and the project lead of OpenJDK Mobile. You’ll receive a link in your inbox to access your eBook. And as a consequence, quantum simulators can be built that implement the expected behavior. Hence, the stack shown in Figure 1 does not apply to quantum computing. While GPUs use transistors as well, their operation is different from that of CPUs. Figure 2. Johan Vos, ( @johanvos) started to work with Java in 1995. references to concepts that will be explained later in the book This is a hard-to-imagine concept that tells us the qubit is in the 0 state and the 1 state at the same time. This does not mean that it is in the |0> state OR the |1> state; we don't know its current state. Most developers already heard something about Quantum Computing, but to many it seems very abstract, futuristic or mysterious. Quantum computing is on the horizon, ready to impact everything from scientific research to encryption and security. Quantum Computing for Developers: A Java-Based Introduction: Vos, Johan: Amazon.com.au: Books In this article I would like to present a Java library that allow to simulate quantum algorithms. A quantum coprocessor can be integrated with the CPU in a system. Gluon received a Duke's Choice Award in 2015. After applying the Pauli-X gate, this qubit will be in the |1> state, as shown in Figure 5. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. There is a growing consensus among scientists that quantum computers are particularly good for some problems, while classical computers are best for other problems. This leads to the real power of quantum computers. However, many applications in a high-level language leverage both a CPU and a GPU under the hood. Results of applying the Hadamard gate. Next, we measure the qubits and print the value: If you run this application, you'll see the following output: Note that the measured value for the first qubit can be 0 as well, as we expected. Not only are the basic building blocks different, the gates are different as well. Strange comes with a built-in quantum simulator, but it can also use a cloud service to execute programs in a cloud environment (for example, on Oracle Cloud). We then apply two simple gates to each of the two qubits, which can graphically be represented as shown in Figure 7. The Pauli-X gate will bring it from |0> to |1> and the Hadamard gate will bring it to superposition, with equal probabilities for |0> and |1>. Quantum systems promise to be significantly faster for certain types of algorithms, especially in numerical computing … By keeping qubits in a superposition during computations, it is possible to take into account all different options at once. Vos is a Java Champion, a member of the Belgian Java User Group (BeJUG) and Devoxx steering groups, and he is a JCP member. Most developers already heard something about Quantum Computing, but to many it seems very abstract, futuristic or mysterious. We add this step to the program: We then create the second step, in which we apply a Hadamard gate to q and a Pauli-X gate to q, and we add that step to the program: Now that our program is ready, we want to execute it. He received a Duke's Choice Award in 2014 for his work on JavaFX on mobile. The main hardware component to achieve this is the well-known transistor. Not all expectations are equally realistic, though. Introduction to Quantum Computing. App Dev Manager Leonard Woody breaks down the fundamentals of quantum computing from the perspective of a software developer.

Traditional software development, using classical computers, translates a high-level programming language (for example, Java) to operations performed on a large number of (hardware) transistors. It looks like quantum computers will be excellent in solving problems that typically require resources that scale exponentially with the size of the problem and are, therefore, hard or practically impossible to solve using classical computers. Very smart people started to develop quantum algorithms in the last century, and a growing number of algorithms are published now, including algorithms to factor integers, search lists, deal with path optimization, and more. Prices displayed in rupees will be charged in USD when you check out. On a regular basis, there are new reports from research institutes, companies, or governments about breakthroughs in this field. If you use JavaFX to create an application that has a user interface, you use Java code only (and maybe FXML to declare the user interface). Deeplearning4j has a number of implementations for doing the required vector and matrix operations, and some of those leverage GPUs. Quantum Computing is by no means an easy subject. The author however has managed to make it accessible to mere mortals such as myself. However, one of the things that will be shaken by quantum computing is encryption that is based on the theory that it's close to impossible for classical computers to factor large integers into primes. Want to learn about QC, while being able to pass through page 1? In comparison to a traditional computer, the basic unit for a quantum computer is the qubit which can at one time represent the value 0 and 1, by exploiting superposition. The results it produces should be the same as the results on a real hardware quantum computer—but the simulator will be much slower since the quantum effects that speed up quantum hardware have to be simulated using classical software. Java based Quantum Computing library. A bit can hold a single digit of information, and its value is either 0 or 1. Although it may take many years before quantum computers are large enough to make integer factorization easily solvable, as software developers we know it also takes many years to change systems and have them using safer technologies. If we have two qubits, those can represent four states (00, 01, 10, and 11), again with different probabilities.
