IEEE PCJS Broadcast Technology Society is excited to announce the following talk: Digital Television Standards and Their Worldwide Impact Guest Speaker: Glenn Reitmeier Location: Computer Science Building (CS 105) Princeton University, Princeton, NJ Event: October 28, 2024, starting at 7:00pm to 9:00pm Brief abstract of talk: The development of digital standards for broadcast television was a seminal event - it was a pivot from many decades of analog video technology to the world of digital media and video streaming that today's audiences enjoy all over the world. This talk will discuss the technical roots of analog video standards, how the quest for a high-definition broadcast television standard in the 1990s was met by a radical leap to digital technology, the world's first digital TV standard (ATSC), and the recent development of the ATSC 3.0 standard for internet based broadcasting and streaming. Also discussed will be the adoption of digital television standards throughout the world, how government regulators have managed to transition from analog to digital broadcasting and the commercial impact of standards on consumer electronics products from TVs to smart phones. Speaker Bio: Glenn Reitmeier is widely recognized as a technology visionary and pioneer in the television industry. Throughout his career, he has been a leader in establishing revolutionary new digital standards that are now widely used in video production and in content delivery by over-the-air broadcasting, satellite, cable and video streaming over the internet. Now an independent consultant, Glenn is retired from 17 years at NBC Universal as Senior Vice President, Technology Standards and Policy, where he contributed to industry technical standards and to the technical aspects of the company’s government policy positions and commercial agreements. Previously, Glenn spent 25 years in digital video research at RCA/Sarnoff Laboratories. In addition to leading Sarnoff’s work on digital HDTV, his laboratory also spun out six technology startup companies in digital television and media. Glenn has served the industry as a Board member of the Advanced Television Systems Committee (ATSC), the North American Broadcasters Associations (NABA) and the Open Authentication Technical Committee (OATC), and he has been Chairman of the Board of both ATSC and OATC. He is a SMPTE Fellow and a recipient of the Progress Medal and the Signal Processing Medal. He is also an inaugural member of the Consumer Technology Association’s (CTA) Academy of Digital Television Pioneers, a recipient of the National Association of Broadcasters (NAB) Television Engineering Award for lifetime achievement and a recipient of the ATSC’s Bernard J. Lechner Award for outstanding technical contributions. Glenn holds over 60 patents, has contributed to many Emmy award winning technologies and is recognized in the New Jersey Inventors Hall of Fame. He received his B.E.E from Villanova University and an M.S.E in Systems Engineering from the University of Pennsylvania.

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 combined with a low power current-mode single sideband upconversion I/Q mixer-based RF arbitrary waveform generator (AWG). Implemented in 14nm CMOS FinFET technology, the QSC generates control signals in its target 4.5GHz to 5.5 GHz frequency range, achieving an SFDR > 50dB for a signal bandwidth of 500MHz. With the controller operating in the 4K stage of a cryostat and connected to a transmon qubit in the cryostat’s millikelvin stage, measured transmon T1 and T2 coherence times were 75.5μS and 73 μS, respectively, in each case comparable to results achieved using conventional room temperature controls. In further tests with transmons, a qubit-limited error rate of 7.76x10-4 per Clifford gate is achieved, again comparable to results achieved using room temperature controls. The QSC’s maximum RF output power is -18 dBm, and power dissipation per qubit under active control is 23mW Speaker(s): Sudipto Chakraborty, Agenda: Refreshments Distinguished Lecture Room: B205, Bldg: Engineering Quad, Olden Street, Princeton, New Jersey, United States, 08544
