Dr. Uzi Pereg: "An Information-Theoretic Perspective on Quantum Repeaters"

Weekly seminar

We consider communication over a quantum broadcast channel with cooperation between the receivers. Through this setting, we provide an information-theoretic perspective on quantum repeaters. First, we observe that entanglement resources alone do not increase the achievable communication rates.

Modern quantum algorithms with provable speedups originate historically from three disparate origins: simulation, search, and factoring. Today, we can now understand and appreciate all of these as being instances of a single framework, and remarkably, the essence is how the rotations of a single qu

Abstract: Coherent errors in a quantum system can, in principle, build up much more rapidly than incoherent errors, accumulating as the square of the number of qubits in the system rather than linearly. I will characterize the types of channels that can exhibit such behavior and present a simple pr

Prof. Frank Pollmann: "Exploring Topological Phases on Quantum Processors"

Weekly seminar

Universal quantum computers are potentially an ideal setting for simulating emergent quantum many-body phenomena that are out of reach for classical computers. Here we discuss two applications to the study of topologically ordered systems: First, we represent the ground states of Hamiltonians using
