though this is probably one of the most important open questions in the field of quantum computing.1 In fact, one could also interpret our main theorem as a way to disprove this conjecture: if one finds an efficient algorithm for LWE, then one also obtains a quantum algorithm for approximating worst-case lattice problems.

What is Quantum Computing? - University of Cambridge

Quantum Computing Lecture 1 Anuj Dawar Bits and Qubits 2 What is Quantum Computing? Aim to use quantum mechanical phenomena that have no classical counterpart for computational purposes. Central research tasks include: •Building devices — with a specified behaviour. •Designing algorithms — to use the behaviour.

quantum algorithms for evaluating Boolean formulas. • InPart V, we describe quantum algorithms for simulating the dynamics of quantum systems. We also discuss an application of quantum simulation to an algorithm for linear systems. • InPart VI, we discuss adiabatic quantum computing, a general approach to solving optimization prob-

INTRODUCTION TO QUANTUM MECHANICS - Fisica

. provides an understanding of the power and elegance of quantum mechanics that will make more advanced texts accessible. Chapter 1 provides a qualitative description of the remarkable properties of quantum particles, and these properties are used as the guidelines for a theory of quantum mechanics which is developed in Chapters 2, 3 and 4.

This is the regime where the path integral approach has proven to be very useful. It would be beyond the scope of this chapter even to attempt to give a com-
