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!

Quantbot hosts NYC Quantum Computing Meet up

On Wednesday, September 13 Quantbot had the pleasure of hosting the NYC Quantum Computing group in our office for their monthly meeting.

Vinod Menon, this month's presenter, gave a presentation on "Half-light half-matter quasiparticles (polaritons) as a platform for Hamiltonian simulators and quantum optical nonlinearity".

Tom Crimi, Quantbot's CTO, giving the opening talk about Quantbot.

It was a great night of discussion with great minds. We look forward to hosting future events in our space as we continue to grow in our space.

Vinod Menon is a Professor of Physics at the City College of New York and doctoral faculty at the Graduate Center of the City University of New York (CUNY). He is a fellow of the Optical Society of America (now Optica) and an IEEE Distinguished Lecturer in Photonics (2018-2020). More details about his group can be found at: https://lanmp.org/

And for those curious as to the content of the presentation:
Abstract: Strong light-matter interaction results in the formation of half-light half-matter quasiparticles called polaritons that take on the properties of both its constituents. In this talk I will first introduce the concept of polariton formation in low-dimensional semiconductors. Following this, I will discuss the formation of Bose Einstein like condensates at room temperature using polaritons formed in organic molecules. Approaches to create condensate lattices in such systems and their potential application as Hamiltonian simulators will also be presented. In the second part of the talk, I will present our recent work on polaritons in atomically thin (2D) materials and their potential to reach quantum nonlinearity. Finally, I will discuss our quantum education efforts at the City College of New York (CCNY) including the development of undergraduate level quantum optics lab and the potential for outreach efforts at the high school level using these systems.
