Simon’s algorithm provided the first example of an exponential speedup over the best known classical algorithm by using a quantum computer to solve a particular problem. Originally published in 1994, Simon’s algorithm was a precursor to Shor’s well-known factoring algorithm, and it served as inspiration for many of the seminal works in quantum computation that…
A clear guide to the Bernstein-Vazirani Algorithm, extending knowledge from the Deutsch-Jozsa into more complex algorithms. We’ll explore the Problem, Classical and Quantum Solutions, as well as creating circuits, code, and running the algorithm on Quantum Computers with Qiskit. This is a bonus Part 3 to Quantum Algorithm Untangled’s series on the Deutsch-Jozsa Algorithm. Part…
When learning quantum computing algorithms from a textbook, there is usually a progression from the earliest, simplest algorithms to the later, more complex algorithms. Among the first of these textbook algorithms to be presented is often the Deutsch-Jozsa algorithm, whose small size and seeming simplicity belie its importance. What is the Deutsch-Jozsa algorithm? Using the…
There’s been a lot of hype recently surrounding quantum computers. From IBM releasing their new 127-qubit Eagle Chip, to Xanadu unveiling their Quantum Codebook, there’s been a lot going on in the industry! However, this news might lead one to wonder: Sure, the tech’s cool and all, but what can I actually use a quantum computer for? IBM’s…
Anyone interested in learning quantum computing cannot avoid hearing about Shor’s Factoring Algorithm. It is one of the few textbook quantum algorithms, which means that it remains one of the rare examples of quantum computational advantage. In other words, the algorithm can compute something quantumly that is harder and slower to compute classically. In fact, this particular…
What is Quantum Computing? Quantum Computing is a form of computing that takes advantage of quantum mechanics to process information exponentially faster than classical computers. Classical computers use classical bits which can consist of either a 0 or a 1 to encode information. Quantum computers, on the other hand, use quantum bits, or qubits, like photons, atoms,…
Qubit explained Just like a binary bit is the basic unit of information in classical (or traditional) computing, a qubit (or quantum bit) is the basic unit of information in quantum computing. Quantum computing is driving new discoveries in healthcare, energy, environmental systems, smart materials, and beyond. Qubit vs bit Qubits are represented by a…
What is Quantum computing? Quantum computing is a multidisciplinary field comprising aspects of computer science, physics, and mathematics that utilizes quantum mechanics to solve complex problems faster than on classical computers. The field of quantum computing includes hardware research and application development. Quantum computers are able to solve certain types of problems faster than classical…
Suppose you are a product manager, you want to classify customer reviews in positive and negative classes. Or As a loan manager, you want to identify which loan applicants are safe or risky? As a healthcare analyst, you want to predict which patients can suffer from diabetes disease. All the examples have the same kind…
In real world, not every data we work upon has a target variable. This kind of data cannot be analyzed using supervised learning algorithms. We need the help of unsupervised algorithms. One of the most popular type of analysis under unsupervised learning is Cluster analysis. When the goal is to group similar data points in a…
