viewpointWe show that quantum information geometry can be used to characterize Grover's searching algorithm. Specifically, quantifying the notion of quantum distinguishability between parametric density operators by means of the Wigner-Yanase quantum information metric, we uncover that the quantum searching...
“Quantum Computing Algorithms”(Packt, 2023) by Barry Burd takes the essentials of his introductory college class and brings all that instruction to this book in an easy-to-follow, step-by-step methodology. The first section explores quantum basics, the second what quantum can do for you, ...
quantum computing makes them easy to uncover. Two specific quantum algorithms form thisquantum threat:Grover’s algorithm, which can target Symmetric Key Crypto systems, and Shor’s algorithm, which can quickly decode the integer factorization process used to generate asymmetric key pairs used in PKC...
We present several improvements to the standard Trotter-Suzuki based algorithms used in the simulation of quantum chemistry on a quantum computer. First, we modify how Jordan-Wigner transformations are implemented to reduce their cost from linear or logarithmic in the number of orbitals to a ...
and one line joining two dots, is a 3-qubit gate that will apply a NOT gate on the third qubit provided that the other two qubits are in the |1> state. These series of gates and operations are used for the quantum version of the K-means algorithm, thus to perform quantum clustering...
At IBM Research, we’re inventing what’s next in AI, quantum computing, and hybrid cloud to shape the world ahead.
The two phase-compensation pulses correct residual single-atom phases, ϕ01 and ϕ10, and are used to transform the gate into a canonical CZ. In principle, the compensation phases should be the same, but in practice, we find that better gate performance is achieved by allowing the phases...
“Accurately modeling spin and molecular systems is only the first part of the goal,” said Yao, “In application, we see this being used to solve complex materials science problems. With the capabilities of these two algorithms, we can guide experimentalists in their efforts to control mater...
Laboratory and Microsoft employ high-speed computing to create simulators that imitate genuine quantum devices for executing sophisticated quantum circuits. They recently integrated two distinct kinds of simulations to produce the Northwest Quantum Simulator (NWQ-Sim), which is used to test quantum ...
With input data reduced to the manageably sized coreset, Petros’ team could explore three quantum clustering algorithms. Clusteringis an unsupervised learning technique describing a family of methods that group similar data points in a meaningful way. These groups, or clusters, can then be used fo...
