Abstract: Technological solutions for improving the figures of merit of Edge AI applications

Edge AI applications are calling for specialized ASICs (Application Specific Integrated Circuits) and System-on-Chip accelerators, in order to strongly decrease the power dissipation figure. In the near future, those applications will be based on inference-only tasks: the neural network is learnt offline and the classification tasks run locally. However, as mundane as it might appear, this class of application already necessitates optimized architectures for (1) reducing data movement to a minimum and (2) exploiting sparsity of weights and activations. In the longer run, online learning will also be considered for Edge AI applications, e.g. for lifelong learning or adaptation purposes. However, online learning requires massive memories, for storing all the intermediate activation results (3).

In this presentation, technological solutions will be detailed to address these three challenges, which are today hampering the adoption of advanced Edge AI applications.

Abstract: Si spin qubit challenges for large scale

Quantum computing is expected to extend the high performance computing roadmap at the condition of being able to operate a large number of qubits. Si-based QC appears as a promising approach to build a quantum processor; thanks to the size of the qubits, the quality of the quantum gates and the VLSI ability to fabricate billions of closely identical objects. The quality of Si spin qubits has improved very fast with the introduction of isotopically purified 28Si, as observed by multiple research groups.

In this presentation, we will discuss the architectures to design a large scale quantum computer based on Si spin qubits and we will review the hardware integration choices and the associated challenges both from technology and low level software perspectives.

Abstract: Disruption in Compute: Building the Quantum Computer in a 300mm Fab

For many decades, transistor scaling trends have followed Moore’s law. Many in the industry predict that this trend will hit a roadblock in the near future as the costs, process complexity and even fundamental limiters continue to accumulate. However, the need for increased computing performance is real and must be fulfilled. Quantum computing promises to be the biggest disruptive method to deliver the performance increase in computing (even if only for specific classes of task).

Building a quantum computer is a might task and cooperation is key to bringing to realization. In this talk, we will outline how imec is working to enable the technologies needed for quantum computing. We are taking a broad systems perspective to find the path towards up-scalability and increasing the number of qubits. The focus is on two types of qubits (spin qubits in Si and superconducting qubits) which show high potential towards large scale integration. Imec is fabricating these qubits in its state-of-the-art 300mm fab using the know-how and mindset developed for advanced CMOS scaling. Collaborations are already in place and more being set-up to characterize these devices and operate for quantum computing. The quantum computer will require a lot more that just qubits as it is expected that the circuitry to control these qubits will require a lot more power and space than the qubits themselves. Imec is also working on the cryo-electronics needed for the quantum computer and we will describe some of the activities in this presentation.
