Controlled topological dilution drives cooperative glassy dynamics in artificial spin ice
Davis Crater, Ryan Mueller, Sanjib Thapa +4
It has long been known that disorder, perturbing the energy landscape of magnetic systems, can introduce glassy dynamics. However, the controlled role of increasing disorder in dri…
Fingerprints of classical memory in quantum hysteresis
Francesco Caravelli
We present a simple framework for classical and quantum ``memory'' in which the Hamiltonian at time depends on past values of a control Hamiltonian through a causal kernel. Thi…
Experimental observation of dynamical blockade between transmon qubits via ZZ interaction engineering
Marco Riccardi, Aviv Glezer Moshe, Guido Menichetti +13
We report the experimental realization of strong longitudinal (ZZ) coupling between two superconducting transmon qubits achieved solely through capacitive engineering. By systemati…
Overcoming disorder in superconducting globally driven quantum computing
Riccardo Aiudi, Julien Despres, Roberto Menta +5
We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Ph…
Building globally controlled quantum processors with ZZ interactions
Roberto Menta, Francesco Cioni, Riccardo Aiudi +3
We present a comprehensive framework for constructing various architectures of globally driven quantum computers, with a focus on superconducting qubits. Our approach leverages sta…
Magnetic Memory and Hysteresis from Quantum Transitions: Theory and Experiments on Quantum Annealers
Frank Barrows, Elijah Pelofske, Pratik Sathe +2
Quantum annealing leverages quantum tunneling for non-local searches, thereby minimizing memory effects that typically arise from metastabilities. Nonetheless, recent work has demo…
