Quantum error correction with global control
Roberto Menta, Lindsay Bassman Oftelie, Ashkan Abedi +5
Reaching fault tolerance means scaling qubit counts by orders of magnitude, a jump that conventional superconducting architectures cannot sustain without solving the so-called `wir…
Mitigating quantum decoherence via global optimal control
Ashkan Abedi, Roberto Menta, Julien Despres +3
We show that global optimal control can drastically suppress the impact of decoherence in globally driven superconducting quantum computing architectures, taking as a prototype a r…
A Reservoir Computing Approach to Quantum Gate Synthesis
Francesco Caravelli, Roberto Menta, Antonio Sannia
Quantum gate synthesis is essential for implementing quantum algorithms on real hardware, yet existing methods are often computationally demanding. Here, we introduce a novel appro…
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…
Classical Criticality via Quantum Annealing
Pratik Sathe, Andrew D. King, Susan M. Mniszewski +3
Quantum annealing provides a powerful platform for simulating magnetic materials and realizing statistical physics models, presenting a compelling alternative to classical Monte Ca…
Entropy production bounds for systems running computer programs
Abhishek Yadav, Francesco Caravelli, David Wolpert
Mismatch cost (MMC) is a universally applicable lower bound on the entropy production (EP) of any fixed physical process across a given time interval. In the first part of the pape…
Universally-Charging Protocols for Quantum Batteries: A No-Go Theorem
Pratik Sathe, Francesco Caravelli
The effectiveness of a quantum battery relies on a robust charging process, yet these are often sensitive to initial state of the battery. We introduce the concept of a universally…
Boundary-induced classical Generalized Gibbs Ensemble with angular momentum
Francesco Caravelli, Marc D. Vuffray
We investigate the impact of the boundary shape on the thermalization behavior of a confined system of classical hard disks at low packing fraction and thus in the gas regime. We u…
Quantum Uncertainty Relations for Thermodynamic Energy Flows
Pratik Sathe, Luis Pedro García-Pintos, Francesco Caravelli
The Heisenberg uncertainty relation, which links the uncertainties of the position and momentum of a particle, has an important footprint on the quantum behavior of a physical syst…
Potential Applications of Quantum Computing at Los Alamos National Laboratory
Andreas Bärtschi, Francesco Caravelli, Carleton Coffrin +16
The emergence of quantum computing technology over the last decade indicates the potential for a transformational impact in the study of quantum mechanical systems. It is natural t…
