IEEE Distinguished Lecture: Probabilistic Computing With p-Bits: Optimization, Machine Learning and Quantum Simulation

Room 201 Broadway St, Boulder

IEEE Distinguished Lecture The slowing down of Moore’s Law growth has coincided with escalating computational demands from machine learning and artificial intelligence. An emerging trend in computing involves building physics-inspired computers that leverage the intrinsic properties of physical systems for specific domains of applications. Probabilistic computing with probabilistic bits (p-bits) has emerged as a promising candidate in this area, offering an energy-efficient approach to probabilistic algorithms and applications -. Several implementations of p-bits, ranging from standard complementary metal oxide semiconductor (CMOS) technology to nanodevices, have been demonstrated. Among these, the most promising p-bits appear to be based on stochastic magnetic tunnel junctions (sMTJs) . Such sMTJs harness the natural randomness in low-barrier nanomagnets to create energy-efficient and fast fluctuations, up to gigahertz frequencies . In this talk, I will discuss how magnetic p-bits can be combined with conventional CMOS to create hybrid probabilistic-classical computers for various applications. I will provide recent examples of how p-bits are naturally applicable to combinatorial optimization, such as solving the Boolean satisfiability problem , energy-based generative machine learning models like deep Boltzmann machines, and quantum simulation for investigating many-body quantum systems. Through experimentally informed projections for scaled p-bit computers using sMTJs, I will demonstrate how physics-inspired probabilistic computing can lead to graphics-processing-unit-like success stories for a sustainable future in computing.

The Future of Work: Engaged Leadership and Empowered Teams.

Virtual: https://events.vtools.ieee.org/m/427394

Do you still use a landline with rotary dial to make telephone calls? No! You should not be using mid-20th Century leadership practices either! Twentieth century leadership practices are no longer effective. In today's dynamic business landscape, marked by hybrid and remote work, our greatest challenge isn't just managing effectively—it's leading with trust. For 21st century workplaces, the key to success lies in this trust-based leadership. Why? Because trusted employees are committed employees. To enhance retention by up to 65% and increase productivity by as much as 50%, we need to cultivate Engaged Leadership skills alongside traditional management capabilities. How do we cultivate the Engaged Leadership skills which can engender trust? The answer lies in learning and practice. This workshop uses real stories from industry to illustrate the differences between engaged and disengaged leadership practices, between empowered and disempowered teams, and between trusted and untrusted cultures.
