⚛️🧪 We hope this helps clarify the subtle relationship between quantum and classical descriptions of physical systems. Next up: extending this approach to open quantum systems and the Lindblad equation! What are your thoughts on this mapping?
#PhysicsResearch #SymmetryJournal
⚛️🧪 The non-zero coherence terms in the density operator introduce an angular dependence. It gives us a direct, visual signature of quantum entanglement right in the classical phase space!
#QuantumPhysics #PhaseSpace
⚛️🧪 We compared a mixed state and a pure entangled Bell state. The mixed state is invariant under rotations. But for the entangled state, quantum correlations couple the phases, breaking that radial symmetry.
#TheoreticalPhysics #QuantumEntanglement
⚛️🧪 How does quantum entanglement look in classical phase space? In our latest work, we use integral quantization to show that quantum correlations appear as a lack of radial symmetry. Published in Symmetry! Read more here: doi.org/10.3390/sym18030403

Será que já dá pra pensar em julgar e prender quem prescreveu tratamento precoce na pandemia? Quem organizou e executou o contágio do país? Quem negou vacina?
Algumas pessoas acham que estamos exagerando ao apontar os perigos da instalação de data centers no país, mas estamos aqui para mostrar que essa roupagem de progresso vem às custas de retrocessos sociais e ambientais.
🧪⚛️[3/3] A huge thank you to the Theoretical Physics Coordination at CBPF for the kind invitation and for hosting me. The questions and subsequent discussion were a true highlight and have given me so much to think about.

🧪⚛️[2/3] "From Polarizers to Power Laws: Measuring Quantum Circuit Complexity in Open Systems."
I discussed our findings on how to quantify the complexity of quantum computations when these systems are interacting with their environment. The feedback from such a sharp audience was invaluable.
🧪⚛️[1/3] Thrilled to have presented my work today at the renowned Centro Brasileiro de Pesquisas Físicas (CBPF) in Rio de Janeiro! It's an institution with such a rich history in physics. The energy here is just incredible. 🇧🇷🔬
⚛️🧪(5/5) The future of quantum computing will tackle open systems.Our work is a step towards efficient and practical quantum circuits in the real world! 🚀
⚛️🧪(4/5) Big thanks to the organizers of #ParatyQuantum2025 for a stellar event and to my collaborators at CBPF. The discussions were truly inspiring.
⚛️🧪(3/5) Key finding:The number of gates needed scales as a power law with the desired accuracy. This is a sign of efficient algorithm construction! #QuantumAlgorithms
⚛️🧪(2/5) Our paper: "Quantum circuit complexity for linearly polarized light" We studied open quantum systems, using polarisers as gates to guide states along optimal paths (geodesics). #OpenSystems
⚛️🧪(1/5) Just presented our work on quantum circuit complexity at the Paraty Quantum 2025 workshop!An incredible event for cutting-edge quantum research. #QuantumComputing
Vou fazer um fio sobre pq os próximos meses serão decisivos para gripe aviária e pq vale tomar alguns cuidados desde já.
Na Califórnia, já detectaram gripe aviária em mais de 1/4 dos rebanhos leiteiros. Isso na beira de uma temporada de gripe sazonal, que pode mascarar casos e misturar vírus.
46% dos deputados e senadores são contra a taxação dos super ricos. 70% são contra o fim da escala 6x1. 53% são contra acabar com os supersalários do serviço público. A maior parte da população quer tudo isso.
Conclusão: temos um Congresso q só defende a elite. Congresso inimigo do povo!

I understand now! I remember when I was a kid I saw it as a little cartoon to!
This topic brings me nice memories related to the first time I was really enjoying math.
I don't know why I forget this.
Thank you
By default, I choose the first option "Write B>A and read it out in words", unless it is a specific context that I may need to emphasize "A<B". So, first and second is my move. I never thought this relation as a diagram, and now I am curious about this.
