Spectrally local geometric response at the onset of many-body quantum chaos
George Mihailescu, Pablo M. Poggi
We introduce the spectral density of geometric response, a measure of eigenstate sensitivity across an energy spectrum. Applied to many-body quantum systems, it reveals an exponent…
Quantum optimal control of the Dicke manifold in dipolar Rydberg atom arrays
Ivy Pannier-Günther, Vikas Buchemmavari, Pablo M. Poggi +1
The ability to engineer and control quantum states of many-body systems is a central challenge in quantum information science. For a register of qubits, the full Hilbert space…
Taming quantum systems: A tutorial for using shortcuts-to-adiabaticity, quantum optimal control, and reinforcement learning
Callum W. Duncan, Pablo M. Poggi, Marin Bukov +2
Precise manipulation of quantum effects at the atomic and nanoscale has become an essential task in ongoing scientific and technological endeavours. Quantum control methods are thu…
Quantum ergodicity and scrambling in quantum annealers
Manuel H. Muñoz-Arias, Pablo M. Poggi
Quantum annealers play a major role in the ongoing development of quantum information processing and in the advent of quantum technologies. Their functioning is underpinned by the…
Entangled states from sparsely coupled spins for metrology with neutral atoms
Sridevi Kuriyattil, Pablo M. Poggi, Jonathan D. Pritchard +2
Quantum states featuring extensive multipartite entanglement are a resource for quantum-enhanced metrology, with sensitivity up to the Heisenberg limit. However, robust generation…
Long-Range Interacting Many-Body Systems in the Irrep Basis
Ivy Pannier-Günther, Andrew Kolmer Forbes, Pablo M. Poggi +1
Spin models featuring infinite-range, homogeneous all-to-all interactions can be efficiently described due to the existence of a symmetry-restricted Hilbert subspace and an underly…
