Wednesday, 4/17 at 12pm: Quantum Colloquium - Lin Lin

by Ploucha, Clare

Quantum Colloquium – Prof. Lin Lin Wednesday, April 17, 12:00 PM Jefferson 250 Lin Lin, Professor, Department of Mathematics, UC Berkeley Title: Quantum advantage in scientific computation? Abstract: The advent of error-corrected quantum computers is anticipated to usher in a new era in computing, with Shor's algorithm poised to demonstrate practical quantum advantages in prime number factorization. However, cryptography problems are typically not categorized as scientific computing problems. This raises the question: which scientific computing challenges are likely to benefit from quantum computers? I will first discuss some essential criteria and considerations towards realizing quantum advantages in these problems. I will then introduce some recent advancements in quantum algorithms, especially for simulating non-unitary quantum dynamics and open quantum system dynamics. The first half of the presentation is intended to be accessible to a broad audience, including both theoretical and experimental researchers. Guest presentation will begin promptly at noon

Fwd: EE seminar -- Scott Diddams (April 12)

by Sule, Nishant V.

Notice of today’s EE seminar below: EE has invited Scott Diddams<https://www.colorado.edu/ecee/scott-diddams> (U of Colorado Boulder) to give an EE seminar next week on April 12 (12.30 pm – 13.30 pm). This event will be held on the Cambridge side considering the visitor’s research scope. If you are interested in meeting with him or come to his talk, a signup sheet is available: https://docs.google.com/spreadsheets/d/1ntTzaDotv_qcFGzfdAYVdzdeHFzsg0cSNjL… Friday, April 12 at 12:30 pm Pierce 209 or Zoom<https://harvard.zoom.us/j/93583976073?pwd=clNPaHI0TlNxVEN4Mzc2cE9CUmFEUT09> (Password: 599436) "Optical Frequency Combs and Quantum Metrology" Scott Diddams, Professor of Physics, University of Colorado, Boulder Abstract: The optical frequency comb is one of the most significant advances in laser physics since the development of the laser itself. It has made routine the counting and synthesis of the oscillations of light on the femtosecond time scale, and it is an essential component of all present and future optical clocks and time-transfer systems. It further enables the most accurate measurement of any fundamental physical quantity—that of the quantized energy states of atoms and ions with 18 digits of precision. Despite this close connection to quantum systems, there are no demonstrations of how an optical frequency comb could yield a quantum advantage for metrology. The most important limitation remains in photodetection, where shot noise sets the fundamental signal-to-noise ratio. However, there are important and impactful differences in the detection of frequency comb light that yield surprising results, with time-stationary shot-noise limits being surpassed. We are exploring these limits with the goal of defining the standard quantum limit for metrology with optical frequency combs. Highlights will be provided for measurement scenarios that impact applications in clocks, climate and health diagnostics and exoplanet searches. Moreover, I will discuss the prospects of frequency comb interferometry with non-classical states of light and electric-field-correlation spectroscopy of thermal light that could form a critical component of future long baseline interferometry in the mid and near- infrared. Bio: Scott Diddams holds the Robert H. Davis Endowed Chair at the University of Colorado Boulder, where he is also Professor of Electrical Engineering and Physics. He carries out experimental research in the fields of precision spectroscopy and quantum metrology, nonlinear optics, microwave photonics and ultrafast lasers. Diddams received the Ph.D. degree from the University of New Mexico in 1996. From 1996 through 2000, he did postdoctroral work at JILA, NIST and the University of Colorado. Subsequently, Diddams was a Research Physicist, Group Leader, and Fellow at NIST (the National Institute of Standards and Technology). In 2022 he transitioned to his present position where he also assumed the role of Faculty Director of the Quantum Engineering Initiative in the College of Engineering and Applied Science. As a postdoc Diddams built the first optical frequency combs in the lab of Nobel laureate John Hall, and throughout his career, he has pioneered the use of these tools for optical clocks, tests of fundamental physics, novel spectroscopy, and astronomy. His research has been documented in more than 750 peer-reviewed publications, conference papers, and invited talks. The work of Dr. Diddams and his research group has also been recognized by multiple awards. These include the Distinguished Presidential Rank Award, the Department of Commerce Gold and Silver Medals for "revolutionizing the way frequency is measured”, as well as the Presidential Early Career Award in Science and Engineering (PECASE), the OPTICA C.E.K. Mees Medal, the IEEE Photonics Society Laser Instrumentation Award, and the IEEE Rabi award. He is a Fellow of OPTICA (formerly OSA), the American Physical Society, and IEEE.

Quantum Receivers for Optical Communication

by Smith, Kelly

Hi all, A visitor from Lincoln Labs is giving a talk at Harvard on April 17th that I thought might be of interest to the community. The details are below. Best, Kelly Date: Wednesday, April 17th Time: 1:30 pm Location: J256 *High-Efficiency Quantum-Enabled Laser Comm Receivers: Putting Them In Practical Perspective* Abstract: Quantum processing techniques are being developed in labs around the world in order to try to achieve higher photon efficiency in classical optical communications links. The goal would be to create end-to-end laser communication systems that were less expensive than present systems. For instance, several decibels of receiver improvement might lead to big dollar savings if it meant a smaller telescope could be used. The author will provide a channel-capacity-based investigation of lasercom links transmitting classical data, and compare architectures and performance for receivers with and without quantum techniques. The author: Dr. Don Boroson is a Laboratory Fellow in the Communication Systems Division at MIT Lincoln Laboratory, working largely with the Optical/Quantum Communication Technology Group. He has a long history in this group designing, modeling, building, and demonstrating high data rate laser communications systems for space and other applications. He was the Lead Engineer for the GeoLITE mission, the world's first successful demonstration of high-rate, space-based lasercom, and was the Principal Investigator and Lincoln Program Manager for the NASA Lunar Laser Communication Demonstration project, which set many records including being the first laser communications system to operate at lunar distances. Don is internationally known, is the author of many journal and conference papers, and is an SPIE Fellow.

The discussion will feature a short documentary about the Center’s mission to study the geopolitical and societal implications of quantum innovation. From its inception, quantum mechanics was characterized by lengthy philosophical debates among its founders. Such debates were stifled by the late 1930s, exacerbated by a post-WWII focus on military applications. Today, quantum physicists are often socialized to “shut up and calculate.” Simultaneously, quantum information technologies are promised to deliver unparalleled computing, communication, and sensing advances, impacting areas such as medicine, data processing, and finance. It is time to break the silence and again consider quantum innovation's philosophical, ethical, and political aspects. Just as we hear what these technologies can do for the world, we should ask: what can quantum technologies do to our world?
