Quantum steampunk: Quantum information meets thermodynamics / Yunger Halpern, Nicole (speaker) (University of Maryland)
Abstract:Thermodynamics has shed light on engines, efficiency, and time’s arrow since the Industrial Revolution. But the steam engines that powered the Industrial Revolution were large and classical. [...]

Echos in the Dark: Gravitational waves from colliding ECOs at Atom Interferometers / Banks, Hannah Molly (speaker) (University of Cambridge)
Long-baseline atom interferometers offer an exciting opportunity to explore mid-frequency gravitational waves (GW). In this lecture we will survey the landscape of possible contributions to the total ‘gravitational wave background’ within this frequency band. [...]

Direct detection of light dark matter with superconducting thermometers / Wagner, Felix (speaker) (Austrian Academy of Sciences)
In the past decades, numerous experiments have emerged to unveil the nature of dark matter (DM), one of the most discussed open questions in modern particle physics. Direct detection experiments aim to measure the scattering of DM particles off a target material. [...]

Quantum simulation, control and calibration using Qibo / Robbiati, Matteo (speaker) (Università degli Studi e INFN Milano (IT))
We present the latest developments of Qibo, a full-stack and open-source framework for quantum computing. Qibo was initially born as a quantum circuit simulation tool, but over time we have developed new packages, through which quantum control (qibolab) and quantum calibration (qibocal) can be performed.Through its modular layout for backend abstraction it is possible to change efforlessy between different backends, including an high-performance simulator based on just-in-time compilation able to simulate quantum circuits with large number of qubits (greater than 35). Again due to its modularity, qibo can easily be adopted as a tool for controlling and calibrating self-hosted quantum devices.Our framework is designed for the research world; therefore, after briefly describing it, we will present some examples of work developed using Qibo in which we show the convenience of having access to a tool which can be used to design and test full-stack quantum algorithms.About the speakerMatteo Robbiati graduated in Physics from Università degli Studi di Milano in September 2022 [...]

Stochastic quantum simulations for scattering experiments / Kiss, Oriel Orphee Moira (speaker) (Universite de Geneve (CH))
NEW START TIME: 14:00Simulating many-body quantum systems is a promising task for quantum computers. However, early fault-tolerant devices are not expected to correct arbitrary amounts of error, making the quest for better algorithms an important task [...]

Ab-initio two-dimensional digital twin for quantum computer benchmarking / Pagano, Alice (speaker) (Università di Padova)
Large-scale numerical simulations of the Hamiltonian dynamics of a Noisy Intermediate Scale Quantum (NISQ) computer - a digital twin - could play a major role in developing efficient and scalable strategies for tuning quantum algorithms for specific hardware. Via a two-dimensional tensor network digital twin of a Rydberg atom quantum computer, we demonstrate the feasibility of such a program [...]

Classical Splitting of Parametrized Quantum Circuits / Tüysüz, Cenk (speaker) (CQTA, DESY and Humboldt University of Berlin)
In this talk we will dive into the topic of barren plateaus and investigate a new method to avoid them. Barren plateaus appear to be a major obstacle for using variational quantum algorithms to simulate large-scale quantum systems or to replace traditional machine learning algorithms [...]

Noisy gates approach for simulating quantum computers / Di Bartolomeo, Giovanni (speaker) (QMTS group, Univ. of Trieste) ; Vischi, Michele (speaker)
In the seminar we present a novel method for simulating the noisy behavior of quantum computers, which allows to efficiently incorporate environmental effects in the driven evolution implementing the gates on the qubits. We show how to modify the noiseless gate executed by the computer to include any Markovian noise, hence resulting in what we will call a noisy gate [...]
