My domain at Wigner revolves around the design of quantum algorithms. Specifically, entanglement distillation protocols for multipartite networks. By iteratively applying these non-linear quantum protocols, we aim to obtain an enhanced noise-free entanglement. To achieve this goal, we leverage quantum-classical hybrid machine learning techniques to assist in the implementation of quantum circuits that can establish distilled entanglement with high fidelity. In addition, we are implementing simulations and testing the above mentioned algorithms on real quantum devices.

I am researching a doctorate in the field of quantum computing.
My research focuses on quantum error correction, specifically which quantum computing platforms are best suited to demonstrate the efficiency of the quantum repetition phase-flip code.
We have derived a break-even point above which the encoded logical qubit is advantageous and preserves information longer than a single unprotected physical qubit.

I conducted research on quantum optimization through citizen science, and in my thesis, I demonstrated the realization of a spin-qubit based two-qubit logic gate, specifically the square-root-of-swap gate, through the optimization of a gate pulse shape. This posed a hard quantum mechanical optimization problem, which was gamified and transformed into a game for the public. I designed a platform where gamers drew a pulse shape within a certain time frame. Even recent classical supercomputers may find this multi-parameter optimization problem difficult to solve, but gamification utilizing human senses may be more successful.

I studied the coupling between a qubit and an oscillator in a nano-electromechanical system. In this theoretical work, a charge qubit was implemented using a trapped electron in a suspended carbon nanotube, and was controlled using gate electrodes. The charge states of the qubit were coupled to the vibration modes of the nanotube, and an effective read-out scheme was introduced. I also investigated the ultra-strong coupling regime.

The internship project explores GHZ state distribution in quantum networks under realistic noise conditions. The focus is on modeling a realistic, scalable, long-distance quantum network architecture which implements GHZ state distribution between remote nodes through noisy fibers. To counteract decoherence and gate errors, distillation protocols are implemented at the end nodes and at intermediate stations along the links. The aim is to study trade-offs between fidelity, success probability, resource cost, and latency, and to identify optimal strategies for distributing high-quality GHZ states across long distances.
This work is carried out under the Quantum Internet Alliance (QIA) Internship Programme at the Portuguese Quantum Institute, within the Physics of Information and Quantum Technologies Group.
During the internship, several projects were carried out in the field of quantum protocols. These included the study of non-linear iterative protocols on 2- and 3-qubit systems, with a focus on entanglement generation and state evolution. The dynamics of these protocols were analyzed, revealing chaotic behavior under certain conditions. Quantum circuits were implemented using Qiskit to simulate and test these effects, supported by numerical analysis and visualization in Python to explore convergence properties and bifurcations in the system.
