Statistics of topological defects across a phase transition in a superconducting quantum processor / Teplitskiy, Daniil (CERN) ; Kiss, Oriel (CERN) ; Grossi, Michele (CERN) ; Mandarino, Antonio (Gdansk U. ; Milan U.)
When a quantum phase transition is crossed within a finite time, critical slowing down disrupts adiabatic dynamics, resulting in the formation of topological defects. [...]

Counterdiabatic optimized driving in quantum phase sensitive models / Barone, Francesco Pio (CERN ; Padua U.) ; Kiss, Oriel (CERN) ; Grossi, Michele (CERN) ; Vallecorsa, Sofia (CERN) ; Mandarino, Antonio (Gdansk U.)
State preparation plays a pivotal role in numerous quantum algorithms, including quantum phase estimation. This paper extends and benchmarks counterdiabatic driving protocols across three one-dimensional spin systems characterized by phase transitions: the axial next-nearest neighbor Ising (ANNNI), XXZ, and Haldane-Shastry (HS) models. [...]

Hybrid Ground-State Quantum Algorithms based on Neural Schrödinger Forging / de Schoulepnikoff, Paulin (Ecole Polytechnique, Lausanne ; CERN) ; Kiss, Oriel (CERN) ; Vallecorsa, Sofia (CERN) ; Carleo, Giuseppe (Ecole Polytechnique, Lausanne) ; Grossi, Michele (CERN)
Entanglement forging based variational algorithms leverage the bi-partition of quantum systems for addressing ground state problems. The primary limitation of these approaches lies in the exponential summation required over the numerous potential basis states, or bitstrings, when performing the Schmidt decomposition of the whole system.

Importance sampling for stochastic quantum simulations / Kiss, Oriel (CERN ; U. Geneva (main)) ; Grossi, Michele (CERN) ; Roggero, Alessandro (Trento U. ; INFN, Trento)
Simulating many-body quantum systems is a promising task for quantum computers. However, the depth of most algorithms, such as product formulas, scales with the number of terms in the Hamiltonian, and can therefore be challenging to implement on near-term, as well as early fault-tolerant quantum devices.
