Quantum firmware: optimal control for quantum computers and simulators

Tommaso Calarco

Quantum optimal control has been shown to improve the performance of quantum technology devices up to their limits in terms e.g. of system size and speed of operation. This talk will review our recent results with a variety of quantum technology platforms, and introduce our newly developed software for automatic calibration of quantum operations - the fundamental building block of next-generation quantum firmware.

Rydberg Atom-Enabled Spectroscopy of Polar Molecules via Förster Resonance Energy Transfer

Sabrina Patsch, Martin Zeppenfeld, Christiane P. Koch

Non-radiative energy transfer between a Rydberg atom and a polar molecule can be controlled by a static electric field. Here, we show how to exploit this control for state-resolved, non-destructive detection and spectroscopy of the molecules, where the lineshape reflects the type of molecular transition. Using the example of ammonia, we identify the conditions for collision-mediated spectroscopy in terms of the required electric field strengths, relative velocities, and molecular densities. Rydberg atom-enabled spectroscopy is feasible with current experimental technology, providing a versatile detection method as a basic building block for applications of polar molecules in quantum technologies and chemical reaction studies.

Rydberg‐Atom Graphs for Quadratic Unconstrained Binary Optimization Problems

Andrew Byun, Junwoo Jung, Kangheun Kim +4 more

Abstract There is a growing interest in harnessing the potential of the Rydberg‐atom system to address complex combinatorial optimization challenges. Here an experimental demonstration of how the quadratic unconstrained binary optimization (QUBO) problem can be effectively addressed using Rydberg‐atom graphs is presented. The Rydberg‐atom graphs are configurations of neutral atoms organized into mathematical graphs, facilitated by programmable optical tweezers, and designed to exhibit many‐body ground states that correspond to the maximum independent set (MIS) of their respective graphs. Four elementary Rydberg‐atom subgraph components are developed, not only to eliminate the need of local control but also to be robust against interatomic distance errors, while serving as the building blocks sufficient for formulating generic QUBO graphs. To validate the feasibility of the approach, a series of Rydberg‐atom experiments selected to demonstrate proof‐of‐concept operations of these building blocks are conducted. These experiments illustrate how these components can be used to programmatically encode the QUBO problems to Rydberg‐atom graphs and, by measuring their many‐body ground states, how their QUBO solutions are determined subsequently.
