In our new preprint (arxiv.org/abs/2111.03038), we show how to find the wave function of a universe on a quantum computer. The procedure is tested for quantum cosmology with a cosmological constant (de Sitter model). #Quatum #Cosmology #QuantumComputing #QuantumCosmology

Our new preprint addresses the problem of secure key exchange in hybrid quantum (QKD) networks (with trusted nodes). arxiv.org/abs/2205.03174 #Quantum #QKD #Networks #Security

The COST Action COST CA18108: QG-MM 🏳️‍🌈 review paper “#Quantum #gravity phenomenology at the dawn of the #multimessenger era - A review,” to which we had the pleasure to contribute, has recently been published in the Progress in Particle and Nuclear Physics: sciencedirect.com/science/articl…

Recently, we introduced a method of solving the Wheeler-DeWitt equation (H Psi = 0) on a #quantum computer. Our approach paves the way to solving the equation for complex configurations in #quantumgravity. The results have just been published in Physical Review D.

Let us recommend the interdisciplinary workshop WMLQ 2022 which will start tomorrow in Warsaw. Quantum Cosmos Lab will be represented by Artur Miroszewski (PostDoc) and Grzegorz Czelusta (Ph.D. student), who will give their talks on the first day of the workshop. #Quantum #ML

On today's arXiv, you can find the first results from our European Space Agency co-funded project on applying quantum machine learning to satellite data analysis, conducted in collaboration with KP Labs and #ESAPhilab. arxiv.org/abs/2302.08270 #quantum #space

Our next step toward large-scale quantum simulations of quantum spacetime, which may bring us an understanding of the possible emergence of classical spacetime from the quantum degrees of freedom (atoms of space). arxiv.org/abs/2304.03559 #Quantum #Gravity #QuantumGravity #LQG

It gives me great pleasure to teach about Bogolyubov transformation and quantum particle creation. I cover this topic at the beginning of the discussion of quantum field theory on the curved spacetimes as a part of my Introduction to #Quantum #Gravity course. #QuantumGravity

Experience the ease of simulating quantum spacetime by playing with our Python & PennyLane codes (used in our recent preprint "Quantum circuits for the Ising spin networks" (arXiv:2304.03559)) shared on GitHub: github.com/Quantum-Cosmos… #LQG #Quantum #QuantumGravity

Every event horizon has a specific nonzero temperature. Today, I explained to my #quantum #gravity course students how it works for de Sitter's cosmological horizon. The Penrose diagrams are invaluable in the teaching process.

One of our two contributions to the International Geoscience and Remote Sensing Symposium IEEE IGARSS 2023 is available at arxiv.org/abs/2306.14515 . This piece of research explores an optimization procedure for #quantum kernels tailored specifically for satellite data analysis.

Happy to share our new article on the geometric approach to quantum complexity. I'm delighted to have collaborated with my brilliant Ph.D. student, Satyaki, and Martin Bojowald, on the project. arxiv.org/abs/2307.13736 #quantum #complexity #geometry

I'm sharing my thoughts on the issue of the computability of reality and how we try to study it through quantum simulations of physics at the Planck scale. jakubmielczarek.com/2023/08/22/is-… #quantum #cosmos #computing #QuantumGravity #LQG

We are happy to announce that our recent article on #quantum analysis of #satellite data has just been published in the IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. The article is accessible through Open Access: ieeexplore.ieee.org/document/10214…

It is quite surprising but in our new article, we have demonstrated that Planck-scale effects may result in a sizable accumulation of quantum squeezing of light over astronomical distances.  #QuantumAstronomy #QuantumGravity arxiv.org/abs/2308.13788

Sharing our recent results on geometric quantum complexity. The newly developed methods have enabled us to calculate the complexity of scalar fluctuations in the de Sitter universe. The findings confirm that complexity grows on scales beyond the horizon. arxiv.org/abs/2407.01677

Our article on geometric #quantum #complexity has been published in the Journal of High Energy Physics (JHEP). We are currently working on applying these results to understand the complexity of quantum gravitational systems. link.springer.com/article/10.100…

In our new article, we introduced a tensor network representation for a class of geometric states in loop #quantum #gravity. This opens new prospects for understanding the relationship between loop quantum gravity and holographic duality. #LQG arxiv.org/abs/2410.18812
