Abstracts:

Towards Scalable Quantum Computers
This focus topic will examine recent advances towards scalable quantum information devices. The topic will include experimental talks on both solid state and AMO qubit technologies with an emphasis on improved gate fidelities and the development of integrated systems. It will also include theoretical talks on improvements in quantum error correction, quantum control, and proposals for scalable architectures.

Hybrid Quantum Systems
This focus topic will examine recent experimental and theoretical developments in hybrid quantum systems that combine quantum system of multiple types. Examples range from quantum dots coupled to microwave cavities to trapped ions coupled to micromechanical resonators.
Organizer: Guido Burkard, University of Konstanz

Adiabatic Quantum Computation and Quantum Annealing
Adiabatic models of quantum computation and quantum annealing perform computational tasks by evolving the system under a slowly changing Hamiltonian. This topic will focus on the theory and applications of adiabatic quantum computers and quantum annealers, and challenges for error suppression and correction on these devices.
Organizer: Daniel Lidar, University of Southern California

Finite-size Quantum Information Theory 
A growing topic of interest in quantum information theory is to understand what the capabilities are for a finite number of quantum systems. Traditionally, the focus has been on asymptotics and there has been a disconnect between the theory and what is possible in practice. In the past three years, the theoretical tools have sharpened significantly and we can answer questions such as "How many qubits can I send with 100 channel uses if I desire an error probability no larger than 10-6 ?" Answers to such questions place fundamental limitations on small quantum computers and are the focus of this session.
Organizer: Mark Wilde, Louisiana State University

Quantum Characterization, Validation, and Verification
As reported errors in quantum gates approach fault-tolerance thresholds, it becomes more important to confirm the methods by which errors are assessed and gate functions are determined. This topic will include recent advances in tomography and benchmarking methods, tests for detecting coherent errors, and appropriate error bounds for quantum error correction.
Organizer: Charles Tahan, Laboratory for Physical Sciences, University of Maryland

Quantum Information and Thermodynamics
It is increasingly apparent that quantum entanglement offers a powerful tool to describe physics. This is necessary to develop realistic proposals for measuring entanglement as well as other quantum information quantities from physical quantities. In the past decade, owing to the control of small-scale devices such as quantum heat engines and electronic circuits, thermodynamics has become part of the bedrock to understand how to measure information quantities in the physical world. Establishing thermodynamics in quantum scales requires a quantum description for exchange of physical quantities such as energy, charge, spin, etc. This requires generalization of information correlations that sometimes goes beyond standard definitions for entanglement. These correlations in condensed matter and information theory have been realized and are the driving force behind recent developments.
Organizer: Mohammad Ansari, TU Delft

Gravity and Quantum Information
Quantum information is providing a fresh look at the gravity-quantum interface. Experiments range from high-precision measurements of the gravitational field using quantum systems all the way to actual large quantum superposition states of clocks or increasingly massive objects, where experiments may be in reach in the near future. In addition, the relevance of quantum information concepts for studying fundamental properties of space-time.
