A Cornerstone of Quantum Computing Quantum Phase Estimation (QPE) stands as a fundamental algorithm in the realm of quantum computing, renowned for its efficiency in estimating the phase (eigenvalue) of a unitary operator. This capability is crucial for unveiling properties of quantum systems that remain inaccessible to classical computational approaches. The Emergence of QPE in…
Variational algorithms are considered among the leading candidates for finding some of the first useful applications of quantum computing. However, noise in quantum hardware limits the number of operations we can run in a quantum circuit before errors accumulate and invalidate the result.Quantum error correction techniques will eventually resolve these errors in fault-tolerant quantum computers….
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…
