Proposed CCNY Quantum Institute Earns $5M NSF Funding
August 17, 2023
ExpandQISE program image courtesy of the National Science Foundation The City College of New York is establishing a state-of-the-art quantum institute, funded by a five-year $5 million grant from the National Science Foundation [NSF], to advance quantum research.
Conceptualized by City College physicist Alexander Khanikaev – recipient of the NSF’s prestigious Special Creativity Award in 2021, and one of the most Highly Cited Researchers (HCR) worldwide in 2022 – The City College of New York Quantum Institute comprises leading experts in quantum at CCNY and scientific partners from Nokia Bell labs and the University of Central Florida College of Optics and Photonics (CREOL/UCF). The latter’s Andrea Blanco-Redondo is co-principal investigator on the project.
The CCNY experts and other co-PIs include:
- Roger Dorsinville, chair of electrical engineering in the Grove School of Engineering;
- Carlos Meriles, professor of physics in the Division of Science; and
- Vinod Menon, professor of physics.
The Institute also will include two quantum-dedicated faculty in electrical engineering and physics that will be hired with plans of expanding CCNY’s educational programs in quantum information sciences and applications.
Khanikaev said the new program and the quality of its faculty would make CCNY one of the leading institutions in quantum research.

CCNY team in Quantum algorithm breakthrough.
Researchers led by City College of New York physicist Pouyan Ghaemi report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers. Their paper, entitled "Creating and Manipulating a Laughlin-Type ν=1/3 Fractional Quantum Hall State on a Quantum Computer with Linear Depth Circuits," appears in the December issue of PRX Quantum, a journal of the American Physical Society.

Hernan Makse was awarded a NIH-NIBIB R01 grant "Application of the principle of symmetry to eural circuitry: From building blocks to neural synchronization in the connectome", PD: Makse, co-PD: Manuel Zimmer (University of Vienna) to study the neural networks of C. elegans with physical symmetry principles and fiber bundles, like in particle physics. Grant Number: 1R01EB028157-01A1, $1,064,970. And we have a trilogy of nice papers on the matter: F. Morone, H.A. Makse.

The 302-neuron connectome of the nematode C. elegans has been completely mapped, yet the design principles that explain how the connectome structure determines its function are unknown. Here, the authors show that physical principles of symmetry and mathematical tools of symmetry groups can be used to understand C. elegans neural locomotion circuits.

Fibration symmetries uncover the building blocks of biological networks
The success of symmetries in explaining the physical world, from general relativity to the standard model of particle physics and all phases of matter, raises the question of why the same concept could not be equally applied to explain emergent properties of biological systems. In other words, we ask—if life is an emergent property of physics—why the same symmetry principles that explain physics could not explain the organizing principle of life. Here we show that a particular form of symmetry, called symmetry fibration, explains the building blocks of biological networks and other social and infrastructure networks. This result opens the way to understand how information-processing networks…

Homogeneous Crystallization in Cyclically Sheared Frictionless Grains
Many experiments over the past half century have shown that, for a range of protocols, granular materials compact under pressure and repeated small disturbances. A recent experiment on cyclically sheared spherical grains showed significant compaction via homogeneous crystallization (Rietz et al., 2018). Here we present numerical simulations of frictionless, purely repulsive spheres undergoing cyclic simple shear via Newtonian dynamics with linear viscous drag at fixed vertical load. We show that for sufficiently small strain amplitudes, cyclic shear gives rise to homogeneous crystallization at a volume fraction $\ensuremath{\phi}=0.646\ifmmode\pm\else\textpm\fi{}0.001$. This result indicates…

Contact network changes in ordered and disordered disk packings
We investigate the mechanical response of packings of purely repulsive, frictionless disks to quasistatic deformations. The deformations include simple shear strain at constant packing fraction and at constant pressure, “polydispersity” strain (in which we change the particle size distribution) at constant p (21 kB)

Circuits with broken fibration symmetries perform core logic computations in biological networks
Author summary We show that the core functional logic of genetic circuits arises from a fundamental symmetry breaking of the interactions of the biological network. The idea can be put into a hierarchy of symmetric genetic circuits that reveals their logical functions. We do so through a constructive procedure that naturally reveals a series of building blocks, widely present across species. This hierarchy maps to a progression of fundamental units of electronics, starting with the transistor, progressing to ring oscillators and current-mirror circuits and then to synchronized clocks, switches and finally to memory devices such as latches and flip-flops.
