A principled link between noise resilience and circuit expressivity provides a roadmap for navigating barren plateaus and optimizing the training of variational quantum algorithms.

🚨 New paper 📜 https://t.co/iEzAShY128. Very excited about this really nice work with colleagues @DrYacineHaddad, @vincecr0ft, and @GrosQmichi at @CERN and my PhD candidate Kaidi Xu.

Main contributions:
- Development of a hybrid quantum–classical framework to compute leading-order helicity amplitudes for e+e- collisions on gate-based quantum hardware.
- Encoding of external kinematics into single-qubit Weyl spinors and coherent combination of diagrammatic contributions within a single quantum circuit.
- Reconstruction of differential cross sections and implementation of binned likelihood fits to precision e+e- data.
- Extraction of bounds consistent with Standard Model expectations, establishing a concrete interface between quantum-assisted amplitude evaluation and collider EFT analyses.

Outlook:
- Scalable extension to more complex scattering processes.
- Systematic exploration of EFT parameter spaces using quantum resources.

Hear from Michele Grossi (@GrosQmichi), Coordinator of Hybrid Quantum Computing Infrastructure and Algorithms at CERN Quantum Technology Initiative (@CERNquantum), on why PennyLane (@PennyLaneAI) is their go-to platform for research.👇

Add some ANNNI Ising to the mix! 🌀🎂

Based on research by CERN-QTI (@CERNquantum), this new PennyLane demo explains the phase diagram of the Axial Next-Nearest-Neighbor Ising (ANNNI) model with different quantum machine learning (QML) models.

It is long due in QML to deviate from the parametrized circuit based paradigm. As a path forward, we fix some issues that were previously attributed to quantum Boltzmann machines. Our framework provides a connection to restricted Boltzmann machines and allows us to derive closed-from expressions that were not possible before!

See Maria's thread for more details.

[Maria Demidik @maria_demidik]

We introduce an sqRBM with quantum hidden units, while visible units remain classical. Benefits: closed-form expression for probabilities and gradients 👉simulation up to hundreds of units (qubits) on your laptop 😎

BREAKING: The CEO of Crocs shoe company has expressed his opinion on near-term viability of quantum computers. According to his expert take, in the next 2 years the new materials discovered by quantum computers will improve the durability of Crocs shoes by 23%. #quantumstocks

[Manuel Rudolph @QuantumManuel]

Our group's work on the trainability of quantum generative models was published today in @npj Quantum Information! We establish a framework that categorizes types of generative loss functions, allowing us to prove surprisingly general trainability results. 🧵👇

I was having fun observing the Kibble-Zurek mechanism using the @meetIQM ⚛️ quantum computer.

We leveraged a symmetry-based noise renormalization strategy to perform up to 16 Trotter steps 🏁.

with @Quantonio_ , @GrosQmichi and @CERNquantum.

[Michele Grossi @GrosQmichi]

@MvsCerezo @gcrognaletti @CERNquantum Thanks! We got inspired, also on the meme side 😅

[Michele Grossi @GrosQmichi]

🔔 new paper out! We tried to answer important questions about noise, loss concentration. Enjoy the 🧵from @gcrognaletti who made a super work! @CERNquantum

[Giulio Crognaletti @gcrognaletti]

What if noise-induced barren plateau was not the only effect that noise can have on the loss function in variational quantum computing?

#CERN has enabled Europe to lead the world in high-energy physics, accomplishing what no single country could sustain alone. Its flagship project, the Large Hadron Collider (#LHC), has cemented Europe’s leadership in particle physics. – “The future of European competitiveness”, a report by Mario Draghi, published by the @EU_Commission on 9 September 2024.

The report looks into the future challenges faced by the industry and companies in the European Union. It highlights the importance of research and technology infrastructures as drivers of innovation, and suggests, among other things, investing into CERN’s future: “Refinancing CERN and ensuring its continued global leadership in frontier research should be regarded as a top EU priority, given the objective of maintaining European prominence in this critical area of fundamental research, which is expected to generate significant business spillovers in the coming years.”
