Quantum computing is an emerging technology, with the potential to outperform classical computing (at least for some specific computationally hard problems). To reach this goal, scientists estimate that one needs millions of qubits operating at 99.9% fidelity (10^-3 error per gate). The best quantum computer currently available are limited to tens of qubits with 10^-2 errors. What can we do with these quantum computers? Recent works by early adopters show that current quantum computers on the cloud can be used to solve simple quantum molecules, realize foundational demonstrations with shallow algorithms, study the dynamics of quantum systems, and more. The Quantum computing on the cloud – Early Adopters Meeting (QEAM21) will review the current usage of quantum computers for industrial and academic purposes, in Israel. All active researchers in the field are welcome to submit an abstract below. Preference will be given to works that are either published or submitted to the arXiv.

## Seminar Lecture -Mr. Yuval Kolodny

16 June, 2021

Seminar Lecture of the Dept. of Applied Physics

Wednesday, June 16 at 11:30

Location: The seminar hall (room number 109) of the Institue of Earth Sciences

"Quantum-Classical Control of Energy Transfer in Biological Light-Harvesting Systems and in Bio-Inspired Nano-devices "

Speaker: Mr. Yuval Kolodny

Affiliation: Prof. Yossi Paltiel, Applied Physics Department, The Hebrew University of Jerusalem, Israel

Photosynthesis is one of the fundamental processes of life. Its first step is light-harvesting: absorbing sunlight and transferring its energy to reaction centers, where it is converted to chemical energy. Sophisticated light-harvesting protein complexes have evolved to harvest light with extraordinary efficiency. The underlying physical mechanism of these complexes are still not fully understood, and the intriguing option that the mechanism involves quantum coherence, has been the recent focus of the growing field of quantum biology. In this talk I will share several approaches to study the control of energy transfer in these systems at the nanoscale: from organisms at their natural habitats, through bacteria grown under controlled conditions in the lab, to bio-mimicry using hybrid nano-structures of quantum dots and organic linkers.

Title: Measurement induced entanglement transitions

Abstract: The resilience of quantum entanglement to a classicality-inducing environment is tied to fundamental aspects of quantum many-body systems. The dynamics of entanglement has recently been studied in the context of measurement-induced entanglement transitions, where the steady-state entanglement collapses from a volume-law to an area-law at a critical measurement probability~$p_{c}$. Interestingly, there is a distinction in the value of $p_{c}$ depending on how well the underlying unitary dynamics scramble quantum information. For strongly chaotic systems, $p_{c} > 0$, whereas for weakly chaotic systems, such as integrable models, $p_{c} = 0$.

In this talk, I will discuss the measurement induced transitions in 2 classes of underlying unitary dynamics given by

1. Many-body localized Hamiltonians (MBL)
2. Random Clifford circuits

They are both efficiently simulable on classical computers. Eigenstates of MBL systems are area-law entangled, therefore can be expressed as shallow quantum circuits while polynomial time algorithms exist for simulation of Clifford circuits. I will highlight the nature of measurement induced transitions in these systems and discuss some of the open questions.
