This presentation provides the physical case for a conservative magnetic vector potential and magnetic vector potential in general as a physical quantity. The derivation of Lorenz Gauge and its present application will be reviewed. The application of Lorenz Gauge to derive the conservative magnetic vector potential is shown. When applied this way, Lorenz Gauge is... Read more →

This talk will cover practical challenges for cryogenic CMOS designs for next-generation quantum computing. Starting from system level, it will detail the design considerations for a non-multiplexed, semi-autonomous, transmon qubit state controller (QSC) implemented in 14nm CMOS FinFET technology. The QSC includes an augmented general-purpose digital processor that supports waveform generation and phase rotation operations... Read more →
