Lattice QCD on modern GPU systems
Quantum computing is emerging as a new paradigm for the solution of a wide class
of problems that are not accessible by conventional high performance computers
based on classical algorithms. Quantum computers can in principle e?ciently solve
problems that require exponential resources on classical hardware, even when using
the best known classical algorithms. In the last few years, several...
Real-time correlators are difficult to evaluate on a classical computer due to the sign problem. Simulations performed on a quantum computer naturally give real-time correlators. From these real-time correlators, both parton distribution functions and the hadronic tensor may be obtained. In this talk, I describe three ingredients for the evaluation of the hadronic tensor on a quantum computer...
In this work we want to demonstrate the effectiveness of the new D-Wave quantum annealer, D-Wave 2000Q, in dealing with real world problems. In particular, it is shown how the quantum annealing process is able to find global optima even in the case of problems that do not directly involve binary variables. The problem addressed in this work is the following: taking a matrix V, find two...
We illustrate the application of Quantum Computing techniques to the investigation
of the thermodynamical properties of a simple system, made up of three
quantum spins with frustrated pair interactions and affected by a hard sign problem
when treated within classical computational schemes.
We show how quantum algorithms completely solve the problem, and discuss how
this can apply to...
