The Intelligence Advanced Research Projects Activity (IARPA) and the Army Research Office (ARO) are pleased to announce a workshop on challenges to quantum coherent operations in a multi-qubit environment. The purpose of this meeting is to identify, on a technology specific basis, the primary difficulties that are likely to be encountered as qubit systems beyond typical current experiments with one, two, or three qubits are pursued. Topics of interest include, but are not limited to: controllable qubit interactions, miniaturization and integration to increase qubit density, new physics arising from the assembly of many-qubit systems, and process and state validation for larger systems. The output of the workshop will serve to guide future funding opportunities in quantum information processing at IARPA and ARO.

The workshop aims to address the following questions:

Given a particular qubit technology (that has already demonstrated full single qubit control), what are the challenges facing this system as it grows into the multiple qubit regime?
In a system with multiple qubits, what will be the mechanism(s) through which these qubits interact? How can these interactions be well enough controlled to achieve reliable, scalable logic gates? Do they contribute to decoherent processes?
What new physics must be taken into account for the benefit of, or hindrance to, many qubit operations?
Are there any fundamental results that will inform the community of possible roadblocks that may be encountered when growing systems to the multiple qubit regime?
How can cross-talk from the control/readout channel for one qubit, to a bystander qubit, be reduced to a satisfactory level?
What are the specific technologies required to ensure that a robust multi-qubit information processing system can be realized?
As systems grow larger, quantum state and, and even more so, process tomography will become impractical. What other measures will be effective for validating the operations of these systems?

A collaborative workshop over the course of a day and a half is foreseen. The first morning and early afternoon will include talks from invited speakers who will provide insights into the challenges of adding significantly more qubits to their system of expertise. The end of the first day will be devoted to break-out sessions with participants actively contributing to the discussions in small groups. The next morning, reports will be given summarizing the results from each of the break-out sessions. Finally, an opportunity will be given to the attendees to make brief statements that refine and/or add to the content that has been presented.

Because of this collaborative format, it is expected that the participants in this workshop will be leaders from research and scientific groups with significant experience in the field of quantum computing, and allied technologies.
