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…
Global control via quantum actuators
Roberto Menta, Francesco Cioni, Riccardo Aiudi +2
We introduce the concept of quantum actuators as mediators for globally controlled quantum computation. Auxiliary quantum systems act as controllable elements that transiently stor…
Non-Fermi-liquid behaviour of electrons coupled to gauge phonons
Rutvij Gholap, Alexey Ermakov, Alexander Kazantsev +3
We identify overdamped gauge phonons as a new microscopic route to non-Fermi-liquid behaviour in Dirac materials. These phonons couple to electronic currents rather than densities,…
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…
Direct Dark Matter searches with Metal Halide Perovskites
Davide Baiocco, Damiano Marian, Giulio Marino +3
Polar materials with optical phonons in the meV range are excellent candidates for both dark matter direct detection (via dark photon-mediated scattering) and light dark matter abs…
Conveyor-belt superconducting quantum computer
Francesco Cioni, Roberto Menta, Riccardo Aiudi +2
The processing unit of a solid-state quantum computer consists in an array of coupled qubits, each locally driven with on-chip microwave lines that route carefully-engineered contr…
Reply to the comment on "High-Power Collective Charging of a Solid-State Quantum Battery" by Haowei Xu and Ju Li
D. Ferraro, M. Campisi, G. M. Andolina +2
In this short communication we reply to the comment by Xu and Li (arXiv:2411.04132) on our first work on Dicke quantum batteries (Phys. Rev. Lett. 120, 117702 (2018)).
Single-atom dissipation and dephasing in Dicke and Tavis-Cummings quantum batteries
Andrea Canzio, Vasco Cavina, Marco Polini +1
We study the influence of single-atom dissipation and dephasing noise on the performance of Dicke and Tavis-Cummings quantum batteries, where the electromagnetic field of the cavit…
Genuine quantum advantage in non-linear bosonic quantum batteries
Gian Marcello Andolina, Vittoria Stanzione, Vittorio Giovannetti +1
Finding a quantum battery model that displays a genuine quantum advantage, while being prone to experimental fabrication, is an extremely challenging task. In this Letter we propos…
Globally driven superconducting quantum computing architecture
Roberto Menta, Francesco Cioni, Riccardo Aiudi +2
We propose a platform for implementing a universal, globally driven quantum computer based on a 2D ladder hosting three different species of superconducting qubits. In stark contra…
Cavity QED of Strongly Correlated Electron Systems: A No-go Theorem for Photon Condensation
G. M. Andolina, F. M. D. Pellegrino, V. Giovannetti +2
In spite of decades of work it has remained unclear whether or not superradiant quantum phases, referred to here as photon condensates, can occur in equilibrium. In this Letter, we…
Modulated phases of graphene quantum Hall polariton fluids
Francesco M. D. Pellegrino, Vittorio Giovannetti, Allan H. MacDonald +1
There is growing experimental interest in coupling cavity photons to the cyclotron resonance excitations of electron liquids in high-mobility semiconductor quantum wells or graphen…
