Optimizing Atom Transport, Gate-Count and Depth with Parity Twine
Javad Kazemi, Michael Fellner, Riccardo J. Valencia-Tortora +2
We present an efficient implementation of the Parity Architecture for neutral-atom quantum processors. We adapt Parity Twine Networks (PTNs) to different atom layouts, native entan…
Demonstrating Record Fidelity for the Quantum Fourier Transform
Philipp Aumann, Michael Fellner, David Alber +6
We demonstrate the Parity Architecture on quantum hardware, using the quantum Fourier transform (QFT) as a benchmark. As a result, a record performance in both fidelity and qubit c…
Kinetically constrained cavity QED: from blockaded ferromagnetism to long-range quantum scars
Hossein Hosseinabadi, Riccardo J. Valencia-Tortora, Aleksandr N. Mikheev +4
Rydberg-cavity systems are emerging as promising platforms for quantum simulation and quantum information processing. These hybrid architectures combine two complementary interacti…
State-dependent mobility edge in kinetically constrained models
Manthan Badbaria, Nicola Pancotti, Rajeev Singh +2
In this work, we show that the kinetically constrained quantum East model lies between a quantum scarred and a many-body localized system featuring an unconventional type of mobili…
Zeno physics of the Ising chain with symmetry-breaking boundary dephasing
Umar Javed, Riccardo J. Valencia-Tortora, Jamir Marino +2
In few-qubit systems, the quantum Zeno effect arises when measurement occurs sufficiently frequently that the spins are unable to relax between measurements. This can compete with…
Rydberg platform for non-ergodic chiral quantum dynamics
Riccardo J. Valencia-Tortora, Nicola Pancotti, Michael Fleischhauer +2
We propose a mechanism for engineering chiral interactions in Rydberg atoms via a directional antiblockade condition, where an atom can change its state only if an atom to its righ…
Crafting the dynamical structure of synchronization by harnessing bosonic multilevel cavity QED
Riccardo J. Valencia-Tortora, Shane P. Kelly, Tobias Donner +3
Many-body cavity QED experiments are established platforms to tailor and control the collective responses of ensembles of atoms, interacting through one or more common photonic mod…
Kinetically Constrained Quantum Dynamics in Superconducting Circuits
Riccardo J. Valencia-Tortora, Nicola Pancotti, Jamir Marino
We study the dynamical properties of the bosonic quantum East model at low temperature. We show that a naive generalization of the corresponding spin-1/2 quantum East model does no…
Zeno crossovers in the entanglement speed of spin chains with noisy impurities
Abhijit P. Chaudhari, Shane P. Kelly, Riccardo J. Valencia-Tortora +1
We use a noisy signal with finite correlation time to drive a spin (dissipative impurity) in the quantum XY spin chain and calculate the dynamics of entanglement entropy of a bipar…
