Control of complex quantum systems is central to the study of fundamental science of atomic, molecular and bulk materials, as well to development of paradigm-breaking technology such as quantum information processors and exploration of novel directions for biomimetic systems, such as quantum sensors. The field of quantum control is located at the nexus of a number of disciplines ranging from chemical reaction dynamics, ultrafast (attosecond) dynamics, spin dynamics and spectroscopies (NMR, ESR), to quantum optics, quantum information science and mathematical control theory. Rapid advances in both theory and experiment over the past few years have led to a number of important additions to the quantum control "toolbox". Examples include optimal control tools for the design of unitary dynamics, control of open quantum systems, implementations of quantum-limited measurements, development of circuit-QED for superconductors, realizations of ultra-cold molecules in degenerate quantum gases, and the observations of electronic quantum coherence in light-harvesting biomolecules.

This program will bring together researchers from the quantum physics, chemical physics, quantum information, and engineering/mathematical sciences communities with interest in development and application of novel quantum control methodologies to fundamental physical, chemical and biological problems.

The program will focus on the following topics:
  1. Quantum control theory in both closed- and open-quantum systems contexts.
  2. Control of quantum many-body systems via quantum simulation and quantum reservoir engineering and control.
  3. Quantum control for high fidelity and fault tolerant quantum information processing.
  4. Quantum-limited measurements, tomography, and quantum sensors.
  5. Application to attosecond physics and chemistry, with emphasis on control of electron correlations in dynamical processes.
  6. Application to control of quantum states in superconducting circuits, ultracold molecules, and hybrid quantum devices.
  7. Application and study of quantum coherence in biological systems.

There will be an associated conference New Directions in the Quantum Control Landscape during the week of February 25 – March 1.
