Talk Title: Resource-Efficient Quantum Computing by Breaking Abstractions
Talk Abstract: Quantum computing is at an inflection point, where 53-qubit (quantum bit) machines are deployed, 100-qubit machines are just around the corner, and even 1000-qubit machines are perhaps only a few years away. These machines have the potential to fundamentally change our concept of what is computable and demonstrate practical applications in areas such as quantum chemistry, optimization, and quantum simulation.
Yet a significant resource gap remains between practical quantum algorithms and real machines. A promising approach to closing this gap is to selectively expose to programming languages and compilers some of the key physical properties of emerging quantum technologies. I will describe some of our recent work that focuses on compilation techniques that break traditional abstractions, including compiling directly to analog control pulses, compiling for machine variations, and compiling with ternary quantum bits.

Talk Title: Neuromorphic Computing for Real-Time Control at the Edge
Talk Abstract: Neuromorphic computing is a promising future computing technology for a variety of applications. There is tremendous opportunity to apply neuromorphic computing for real-time control applications at the edge because of its native low power operation and temporal processing capabilities. In this talk, a neuromorphic computing approach that includes hardware, software, and an evolutionary optimization-based algorithm is described and several real-time control applications at the edge are demonstrated.

Talk Title: Analog and in-memory computing for power efficient hardware
Talk Abstract: After approximately 100 years of engineering computers, humans have reached performance that rivals biological brains in many ways, while exceeding it in sheer number-crunching capacity. Yet, we took a very different path from biology, and there remains a huge advantage in energy-efficiency for biological information processing systems. I will discuss our work exploring brain-inspired non-von Neumann computing systems for machine learning and optimization problems. We leverage emerging non-volatile and analog devices (e.g., memristors) combined with mature CMOS technology to construct novel circuits and architectures. We have developed non-volatile associative memory circuits for storing and retrieving complex patterns at low area and power consumption. These enable computing applications in network security, genomics, and tree-based machine learning. We use analog operations and intrinsic stochasticity to speed up the solution of intractable optimization problems, forecasting significant improvement over traditional and emerging compute technologies. Finally, I will describe approaches to address the challenges with precision in analog systems through novel error-correcting codes.

Talk Title: Adiabatic CMOS Design for Adiabatic Reversible Computing
Talk Abstract: Adiabatic reversible computing can dramatically reduce heat dissipation by introducing a tradeoff between energy and speed. Adiabatic circuits operate slowly, relative to their RC time constants, and use reversible logic to implement energy efficient computing. Adiabatic CMOS is an immediate implementation of reversible computing that operates CMOS circuits adiabatically by replacing their DC power supplies with ramping clocks. Complex adiabatic CMOS designs have been demonstrated such as a 16-bit adiabatic microprocessor. However, automated design tools are needed to implement larger adiabatic circuits. Furthermore, energy savings using CMOS circuits are ultimately limited by leakage. A new approach, adiabatic capacitive logic (ACL), implements reversible computing by using variable capacitors as pull-up and pull-down networks. ACL uses MEMS relay-like devices that eliminate leakage current and are not limited by passive power. A complete reversible computing system, using adiabatic CMOS or ACL logic gates, needs to consider the implementation of adiabatic ramping clocks. We propose aluminum nitride MEMS resonators as an efficient approach to drive reversible logic gates and recycle the bit energies from the logic. Such resonators can be used to implement a complete reversible computing system that includes both energy efficient clocks and logic and can dramatically reduce heat dissipation.
