An Overview of Quantum Computing at IBM: IBM-Q

Quantum computing has developed from mathematical applications of fundamental quantum mechanics to the realization of an actual multiple qubit computational platform, called IBM-Q, that is accessible to external users. I will give an overview of quantum computing methodologies but focus more specifically on IBM’s approach utilizing Josephson Junctions imbedded in resonator structures that operate at 10 mK. In addition to discussing the mathematical basis of quantum computing, I’ll describe several key quantum gates and how they are implemented in a quantum computer.

Explorations of Fundamental Material & Photochemistry Processes: A New Laboratory

KMLabs and IMEC have partnered to create a new laboratory to explore fundamental material and photochemistry processes critical for scaling in the 300B$ semiconductor industry.  The foundation of semiconductors is the lithography process use to create the individual patterns on chips, and the next generation 13.5nm lithography systems are limited by the photochemistry of these systems.  To address, a set of both old and new techniques are being created in a system to investigate photochemistry for EUV lithography: the fundamental nature of EUV exposure is very different, and fundamentally l

Innovation in the Semiconductor Industry: Implications for Education and Diversity

Abstract: Dr. Laura Oliphant has been at the forefront of technology for over 25 years, first at Intel, as an Engineer and Corporate Venture Capitalist, and now, as a General Partner of a Venture Fund, Board Director and CEO of startups.  She will talk about her career trajectory, the challenges for technology innovation going forward, the implications for education, diversity, and what she wishes that she had known in starting out in her career.

 

Phase and momentum resolved wavepacket imaging using attosecond pulses

An wavefunction plays a central role in quantum mechanics. According to Max Born’s statistical interpretation, square of the amplitude of an electron wavefunction times a unit volume represent a probability to find an electron in the volume. Since an electron has a wave nature, the wavefunction is characterized by phase as well as amplitude. The phase is important for understanding a selectivity of chemical reaction.

 

Lightwave Driven Quantum Dynamics: Molecular Movies and Bloch Waves

Electron recollision in an intense laser field gives rise to a variety of phenomena, ranging from electron diffraction to coherent soft X-ray emission. We have, over the years, developed intense sources of waveform-controlled mid-IR light to exploit the process with respect to ponderomotive scaling, quantum diffusion and quasi-static photoemission. I will describe how we leverage these aspects to “teach” molecules to take a selfie while undergoing structural change.
