Most problems can be solved by many different algorithms, each with its own demands on time and space. Complexity theorists sort problems into categories, called complexity classes, based on the ...

Here we develop a polynomial time algorithm that provably finds the ground state of any 1D quantum ... These complexity-theoretic results directly clash with the practical successes ...

Its Quantum Principal Component Analysis (QPCA) reduces the time complexity of high-dimensional data feature extraction from O(N²) in classical algorithms to O(N), with energy consumption only 1 ...

Climate models can be a million lines of code long and can take months to run on supercomputers. A new algorithm has dramatically shortened that time.
