Cybersecurity: before and after the quantum apocalypse |
Radu Ionicioiu |
|
Quantum computers will soon be powerful enough to break current public-key infrastructure. This will compromise critical infrastructures, mobile banking, software updates, blockchain and digital signatures, among others.
How to prevent this incoming Quantum Apocalypse? I will talk about recent developments in quantum cryptography and the development of the future quantum internet.

Hybrid benchmarking of quantum algorithms |
Andreea-Iulia Lefterovici |
|
Hybrid benchmarking is an alternative way to asymptotic worst-case analysis, gauging the performance of a fault tolerant quantum hardware platform for solving real-world instances of optimisation problem. The overall strategy is to evaluate how a quantum algorithm would perform under idealised assumptions and to identify the ranges where a quantum algorithm could potentially be useful. In this talk, I’ll present a methodology that goes beyond the asymptotic scaling for assessing the potential performance of quantum algorithms in ideal conditions.

Computational quantum advantage for dynamical simulations |
Cristina Cirstoiu |
|
Simulating quantum systems is a central challenge in physics and one of the most promising applications of quantum computers. Today’s quantum hardware can already tackle problems that stretch the limits of classical simulation. This talk gives an accessible overview of the capabilities and limitations of near-term quantum computing, the importance of benchmarking in characterizing performance, and the role of error correction in future scalability. In particular, I will discuss a digital dynamical simulation of a 2D quantum magnetism model on the 56-qubit trapped-ion Quantinuum H2 device. Using combined error suppression and mitigation techniques, we observe Floquet pre-thermalisation at timescales where state-of-the-art classical simulations become extremely difficult, if not infeasible for the particular setting considered.

Weak Values: Interpretations to Applications |
Andrei Cosmin |
|
This talk reviews weak measurements and post-selection with a focus on how weak values are interpreted and used in modern applications. I synthesize two strands that often talk past each other: (i) instrumental uses such as weak-value amplification and minimally invasive inference via weak-valued conditionals, and (ii) recent interpretational claims that treat weak values as properties of the system rather than of the meter.

Breaking the standard quantum limit: quantum metrology and the brave new non-classical world |
Stefan Ataman |
|
The shot-noise limit (SNL) ,also called the standard quantum limit (SQL), is a classical bound that limits the precision when it comes to parameter estimation. With the advent of quantum metrology, the SQL is not anymore a fundamental limit. Indeed, by venturing into the quantum regime one is able to reach the so-called sub-SNL regime. Thus, by taking advantage of this new regime, more precise measurements become possible. As extreme examples of quantum metrology we discuss the success of gravitational wave astronomy by employing squeezed states as well as microscopy at te Heisenberg limit by using highly entangled photons.

Fast gradient-free optimization of excitations in variational quantum eigensolvers |
Thierry Kaldenbach |
|
Finding molecular ground states and energies with variational quantum eigensolvers is central to chemistry applications on quantum computers. Physically motivated ansätze based on excitation operators respect physical symmetries, but existing quantum-aware optimizers, such as Rotosolve, have been limited to simpler operator types. To fill this gap, we introduce ExcitationSolve, a fast quantum-aware optimizer that is globally-informed, gradient-free, and hyperparameter-free. ExcitationSolve extends these optimizers to parameterized unitaries with generators $G$ of the form $G^3=G$ exhibited by excitation operators in approaches such as unitary coupled cluster. ExcitationSolve determines the global optimum along each variational parameter using the same quantum resources that gradient-based optimizers require for one update step. We provide optimization strategies for both fixed and adaptive variational ansätze, along with generalizations for simultaneously selecting and optimizing multiple excitations. On molecular ground state energy benchmarks, ExcitationSolve outperforms state-of-the-art optimizers by converging faster, achieving chemical accuracy for equilibrium geometries in a single parameter sweep, yielding shallower adaptive ansätze and remaining robust to real hardware noise. By uniting physical insight with efficient optimization, ExcitationSolve paves the way for scalable quantum chemistry calculations.

Quantum Hacking: Securing the Future of Quantum Systems |
Cristian Ilie |
|
Quantum technologies promise revolutionary advances in communication, computation, and sensing, but their real‑world implementations are not immune to attack. This talk surveys the emerging field of quantum hacking, highlighting vulnerabilities in devices, algorithms, and communication protocols. From side‑channel leaks and imperfect detectors to protocol manipulation and algorithmic tampering, we will explore how adversaries can exploit these weaknesses — and why building resilient, trustworthy quantum systems is essential for the future.

Mastering ImperfeQtion: From Theory to Practice in the Quantum Wild |
Diana Maimut |
|
Cryptographers and security practitioners are much more concerned nowadays with reducing the distance between the theory behind cryptographic algorithms and their implementations. Even though there is always a gap between theory and practice, an imperfection so to say, we advance in science through the pursuit of superiority and, thus, there's always room for improvement. The presentation aims at setting the stage for a security mindset in a quantum world.

Post-Quantum Cryptography: NIST Standardization and the Mathematics Behind It |
Ionut Anita |
|
This presentation reviews NIST’s progress toward post-quantum cryptography, covering the open call for proposals, the multi-round public evaluations, and the criteria used to select candidate algorithms for standardization. It highlights key milestones—such as the release of draft FIPS for PQC after several evaluation rounds—and summarizes ongoing work on additional signature schemes and on practical guidance for migration from quantum-vulnerable systems. Emphasis is placed on security objectives, expected timelines, interoperability, and concrete preparation steps.

Quantum Machine Learning for Image Classification: Challenges and Perspectives |
Alexandru Ionita |
|
Image classification has been transformed by classical neural networks and advances in computational hardware, motivating the exploration of quantum-enhanced learning models. Quantum machine learning is expected to provide advantages in generalization, representation efficiency, and optimization by leveraging high-dimensional Hilbert spaces and quantum correlations. Both purely quantum neural networks and hybrid quantum–classical models offer distinct pathways toward this goal: the former promise fundamentally new computational paradigms, while the latter enable practical integration of quantum resources within established frameworks. This work examines the comparative advantages and limitations of these approaches in the context of image classification and outlines key challenges and research directions for advancing quantum-enabled learning systems with near-term technology.
