Quantbot Hosts a Second NYC Quantum Computing Meetup!

On Monday February 12th, Quantbot had the opportunity to facilitate this month’s NYC Quantum Computing meetup in our office. This month’s presenter, Mani Chandra from nOhm, presented about “Efficient non-Ohmic Charge Transport in Two-dimensional semiconductors.”

Mani Chandra is the CEO of nOhm Devices, a new startup at MIT. He has a PhD in high-energy astrophysics from the University of Illinois. Some of his achievements include being awarded the Astronomy Department’s Chu award for research excellence and the Illinois Distinguished Fellow from the Urbana- Champaign.

Many people showed up to tonight’s talk and were able to collaborate and share their thoughts on the topic.

Here is a synopsis of tonight’s presenation: Charge transport in semiconductors is usually diffusive (“Ohmic”) due to electrons scattering off defects and phonons, as described by the textbook Ohm’s law. However, in sufficiently clean two-dimensional materials, Ohm’s law breaks down and gives rise to novel “non-Ohmic” charge transport regimes wherein electrons flow like a fluid. These novel regimes – ballistic and hydrodynamic transport – allow for the creation of highly-efficient electronic devices, with much lower power consumption and heat dissipation compared to current generation electronics (which are based on field-effect transistors). I will present an overview of transport physics in semiconductors and talk about our efforts to use non-Ohmic charge transport to design highly-efficient readout electronics that can be co-located with qubits and various quantum sensors in the innermost cryostage of dilution refrigerators, where the cooling power is limited to ~1 mW. The resulting integrated cryogenic electronics will enable the scaling up of quantum systems, similar to the historical progression from discrete transistors to integrated circuits.

Quantbot Lecture Series: “What is Language?” by Ahmar Mahboob

On February 9th, Quantbot had the opportunity to attend to a lecture by Ahmar Mahboob about the nature of language and linguistics.

Prior to the lecture, Ahmar posed questions such as, “Is language a purely human ability or can other life forms learn language too?” and “Is language related to environment and climate change?”. By asking these questions, the main focus of the lecture was uncovered: to understand on a deeper level how language can impact personal and professional lives as well as address societal and environmental concerns.

Ahmar is an Associate Professor of Linguistics at the University of Sydney. Some of Ahmar’s achievements include being a two time recipient of the President of Pakistan’s Award for Highly Qualified Overseas Pakistanis as well as being recognized as the field leader in English language and literature by the Australian Magazine. Additionally, his poetry was inducted into the Australian Poetry Hall of Fame in 2021.

Thank you Ahmar for a great presentation!

DTL Visits NYSE!

On February 2nd, members of our Data and Trading team visited the historic NYSE building for a tour and to watch the Closing Bell.

The visit was a great experience and we are thankful for the opportunity!
