Open 2D Quantum Simulator

Introduction

OPEN-2QS aims to deliver a disruptive change in our capabilities of analog quantum simulation of open 2D many-body systems. For the first time, this will allow us to investigate quantum matter with competing coherent and dissipative processes over extremely long times—a regime that is inaccessible by current technology.

Objectives

This will open a new window for the discovery of emergent dynamical phenomena and states of matter, such as quantum glasses. As any system in Nature eventually couples to an environment, and thus is open, the research program of OPEN-2QS will deliver foundations and concepts whose relevance extends to:

• Chemistry
• Biology
• Information processing

This will also form a basis for future technological innovation.

Methodology

OPEN-2QS’ ambition to redefine the state-of-the-art of open system quantum simulation will be achieved by employing ion crystals, forming two-dimensional geometries, which host over 100 individually addressable and mutually coupled particles.

1. Strong state-dependent tunable dipolar Rydberg interactions will allow for full control over the build-up of quantum correlations in 2D geometries.
2. Vibrational phonon quantum degrees of freedom will enable the engineering of irreversible dissipative processes.
3. The ensuing complex dissipative dynamics will be stabilized over thousands of dissipation cycles via coherence-preserving in-situ optical cooling.

Research Focus

Monitoring quantum trajectories under dissipative dynamics and unprecedented access to reservoir correlation functions will enable the investigation of:

• Collective relaxation behavior
• Exotic forms of matter

We will study the impact of quantum effects on phase transitions, explore correlated dynamics in quantum glasses, test fundamental principles of quantum thermodynamics, and advance numerical algorithms through a close theory-experiment interplay.

Team

To achieve these goals, we have gathered a world-wide unique team of pioneers in:

• Trapped ions
• Rydberg physics
• Quantum non-equilibrium theory
