An Efficient Quantum Algorithm for Lattice Problems Achieving Subexponential Approximation Factor

An Efficient Quantum Algorithm for Lattice Problems Achieving Subexponential Approximation Factor

Explore a groundbreaking quantum algorithm for solving the Bounded Distance Decoding problem with subexponential approximation factor on integer lattices in this Quantum Colloquium talk by Sean Hallgren from Penn State University. Discover how this polynomial-time quantum algorithm achieves an exponential speedup compared to classical methods, marking the first instance of such acceleration for a general lattice problem unrelated to number theory. Delve into the collaborative work with Lior Eldar, understanding the implications of this efficient quantum approach for lattice problems and its potential impact on the field of quantum computing.
