Quantum Simulation of Molecular Dynamics Processes - A Benchmark Study Using Classical Simulator and Present-Day Quantum Hardware
We explore how the fundamental problems in quantum molecular dynamics can be modelled using classical simulators (emulators) of quantum computers and the actual quantum hardware available to us today. The list of problems we tackle includes propagation of a free wave packet, vibration of a harmonic oscillator, and tunneling through a barrier. Each of these problems starts with the initial wave packet setup. Although Qiskit provides a general method for initializing wavefunctions, in most cases …

Automated Test Oracles for Flaky Cyber-Physical System Simulators: Approach and Evaluation
Simulation-based testing of cyber-physical systems (CPS) is costly due to the time-consuming execution of CPS simulators. In addition, CPS simulators may be flaky, leading to inconsistent test outcomes and requiring repeated test re-execution for reliable test verdicts. Automated test oracles that do not require system execution are therefore crucial for reducing testing costs. Ideally, such test oracles should be interpretable to facilitate human understanding of test verdicts, and they must b…

Simulating Human Behavior with the Psychological-mechanism Agent: Integrating Feeling, Thought, and Action
Generative agents have made significant progress in simulating human behavior, but existing frameworks often simplify emotional modeling and focus primarily on specific tasks, limiting the authenticity of the simulation. Our work proposes the Psychological-mechanism Agent (PSYA) framework, based on the Cognitive Triangle (Feeling-Thought-Action), designed to more accurately simulate human behavior. The PSYA consists of three core modules: the Feeling module (using a layer model of affect to sim…

Microsoft bringt "Flight Simulator 2024" auf die Playstation 5
Microsoft gibt ein weiteres Kronjuwel her: Der "Flight Simulator 2024" kommt auf die Playstation 5. Auch Support für PS VR 2 ist geplant.

It's always a good day when you have "always comb foo = bar" and using foo instead of bar changes the run time of your simulation by almost 100K clock cycles.
I have to assume this is a Vivado simulator bug present in both 2024.1 and 2025.1, but don't yet have a fully reduced test case other than an always_ff block somehow having input and output changing on the same clock edge.

Neural Conditional Simulation for Complex Spatial Processes
A key objective in spatial statistics is to simulate from the distribution of a spatial process at a selection of unobserved locations conditional on observations (i.e., a predictive distribution) to enable spatial prediction and uncertainty quantification. However, exact conditional simulation from this predictive distribution is intractable or inefficient for many spatial process models. In this paper, we propose neural conditional simulation (NCS), a general method for spatial conditional si…

Time-Dependent Hamiltonian Simulation via Time-Independent Dynamics in a Larger Space
In this paper, we present a proof-of-concept quantum algorithm for simulating time-dependent Hamiltonian evolution by reducing the problem to simulating a time-independent Hamiltonian in a larger space using a discrete clock Hamiltonian construction. A similar construction was first explored for this simulation problem by Watkins, Wiebe, Roggero, and Lee [PRX Quantum, 2024]. Our algorithm improves upon their work in terms of the dependence on evolution time and precision. In addition, the compl…

I feel like something is fundamentally broken with my simulation setup and I have no clue what it is.
Look at stage3_en here. There are no negedge clocked blocks in my RTL.
This is a simple always_ff @(posedge clk) stage3_en <= stage2_en;
How is this even possible???

Is the Full Power of Gaussian Boson Sampling Required for Simulating Vibronic Spectra Using Photonics?
Simulating vibronic spectra is a central task in physical chemistry, offering insight into important properties of molecules. Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between …
