Sycamore is a quantum processor created by Google Inc.’s Artificial Intelligence division.  It comprises 53 q-bits, while actually having 54 q-bits.  In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum supremacy. To estimate the time that would be taken by a classical supercomputer, Google […]

Forecasting earthquakes is an important problem in Earth science, because of their devastating consequences. The success of earthquake prediction can potentially save many lives. Current scientific studies related to earthquake prediction focus on when and where it will occur and its magnitude. Different technologies have been used to address this, such as mathematical analysis, machine learning algorithms like […]

A Quantum counting algorithm is for efficiently counting the number of solutions for a given search problem. The algorithm is based on the quantum phase estimation algorithm and on Grover’s search algorithm. Counting problems are common in diverse fields such as statistical estimation, statistical physics, networking, etc. As for quantum computing, the ability to perform quantum counting efficiently is needed in order to use […]

The feasibility of a commercial quantum computer was discussed in a prior blog. It was also mentioned that an internet quantum computer service is feasible. While companies like D-Wave in Canada is a commercial quantum computer company, their customers typically ask for build-to-order machines.  Several companies, such as Microsoft, Intel, and IBM have internet-based quantum […]
