Optimized Matrix-Product State Simulations of Quantum Error Correction Circuits
Asier Piñeiro Orioli, Chen Zhao, Guido Masella +3
Simulating quantum error correction (QEC) circuits including non-Clifford gates at scale is important to accelerate progress toward fault-tolerant quantum computing. Here we demons…
Efficient atom rearrangements for quantum error correction primitives with a single AOD
Tom Hartweg, Asier Piñeiro Orioli, Hugo Perrin +1
Neutral-atom quantum computers offer arbitrary connectivity enabled by atom transport. Some logical operations can then be simplified or reduced entirely to geometric rearrangement…
Self-similarity in pandemic spread and fractal containment policies
Alexander F. Siegenfeld, Asier Piñeiro Orioli, Robin Na +2
Although pandemics are often studied as if populations are well-mixed, disease transmission networks exhibit a multi-scale structure stretching from the individual all the way up t…
Entanglement generation in weakly-driven arrays of multilevel atoms via dipolar interactions
Sanaa Agarwal, A. Piñeiro Orioli, J. K. Thompson +1
We investigate the driven-dissipative dynamics of 1D and 2D arrays of multilevel atoms interacting via dipole-dipole interactions and trapped at subwavelength scales. Here we show…
Directional superradiance in a driven ultracold atomic gas in free-space
Sanaa Agarwal, Edwin Chaparro, Diego Barberena +6
Ultra-cold atomic systems are among the most promising platforms that have the potential to shed light on the complex behavior of many-body quantum systems. One prominent example i…
Driven-dissipative four-mode squeezing of multilevel atoms in an optical cavity

We describe a method to create and store scalable and long-lived entangled spin-squeezed states within a manifold of many-body cavity dark states using collective emission of light…
Photon-mediated correlated hopping in a synthetic ladder
Anjun Chu, Asier Piñeiro Orioli, Diego Barberena +2
We propose a new direction in quantum simulation that uses multilevel atoms in an optical cavity as a toolbox to engineer new types of bosonic models featuring correlated hopping p…
Bosonic pair production and squeezing for optical phase measurements in long-lived dipoles coupled to a cavity
Bhuvanesh Sundar, Diego Barberena, Asier Piñeiro Orioli +4
We propose to simulate bosonic pair creation using large arrays of long-lived dipoles with multilevel internal structure coupled to an undriven optical cavity. Entanglement between…
Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
Thomas Bilitewski, Asier Piñeiro Orioli, Christian Sanner +6
The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics,…
Emergent dark states from superradiant dynamics in multilevel atoms in a cavity
