Description:

Scaling quantum computing architectures is trending towards interconnected quantum processing units. For several platforms that require increasingly larger dilution refrigerators, communication between the modular quantum chips based on electrical/RF connections is a limitation due to the limited thermal load capacity the refrigerator can support. Other platforms expected to operate at higher temperatures would eventually face similar challenges. The use of optical interconnects is a potential answer to this scaling challenge to enable multi-chip communication. Such topologies would require conversion of qubits to optical wavelengths for some platforms and, more generally, transmission over a networked quantum computing architecture i.e., notionally a “quantum data center”. Further, control of quantum computers necessitates a hybrid computing framework with both classical and quantum resources. In the primary session, this workshop will encapsulate industry strategies for scaling quantum computing for a variety of qubit technologies with classical control frameworks. A secondary session will cover the technologies and challenges facing quantum interconnects. 
 
 
Session 1 (2h):This session will give an overview of different technologies/platforms the industry is pursuing to build a scalable quantum computing architecture. The Speakers will present their chosen technology, their vision toward a scalable computing platform, the challenges and the role of optics in their roadmap. 


Session 2 (2h): This session will focus on different material platforms and devices as building blocks to enable various essential quantum system functionalities and their integration and packaging aspects to address system challenges induced in particular by the cryogenic environments.
