Signal crosstalk in a flip-chip quantum processor
Sandoko Kosen, Hang-Xi Li, Marcus Rommel +15
Quantum processors require a signal-delivery architecture with high addressability (low crosstalk) to ensure high performance already at the scale of dozens of qubits. Signal cross…
Mitigation of frequency collisions in superconducting quantum processors
Amr Osman, Jorge Fernàndez-Pendàs, Christopher Warren +6
The reproducibility of qubit parameters is a challenge for scaling up superconducting quantum processors. Signal crosstalk imposes constraints on the frequency separation between n…
Universal fidelity reduction of quantum operations from weak dissipation
Tahereh Abad, Jorge Fernández-Pendás, Anton Frisk Kockum +1
Quantum information processing is in real systems often limited by dissipation, stemming from remaining uncontrolled interaction with microscopic degrees of freedom. Given recent e…
Fast multi-qubit gates through simultaneous two-qubit gates
Xiu Gu, Jorge Fernández-Pendás, Pontus Vikstål +8
Near-term quantum computers are limited by the decoherence of qubits to only being able to run low-depth quantum circuits with acceptable fidelity. This severely restricts what qua…
Out of equilibrium chiral magnetic effect and momentum relaxation in holography
Jorge Fernández-Pendás, Karl Landsteiner
We compute anomalous transport phenomena sourced by vector and axial magnetic fields in out of equilibrium setups produced by Vaidya background metrics in holography. We use genera…
Membrane paradigm and RG flows for anomalous holographic theories
Christian Copetti, Jorge Fernández-Pendás
Holographic RG flows can be better understood with the help of radially conserved charges. It was shown by various authors that the bulk gauge and diffeomorphism symmetries lead to…
Anomalous transport and holographic momentum relaxation
Christian Copetti, Jorge Fernández-Pendás, Karl Landsteiner +1
The chiral magnetic and vortical effects denote the generation of dissipationless currents due to magnetic fields or rotation. They can be studied in holographic models with Chern-…
Axial Hall effect and universality of holographic Weyl semi-metals
Christian Copetti, Jorge Fernández-Pendás, Karl Landsteiner
The holographic Weyl semimetal is a model of a strongly coupled topological semi-metal. A topological quantum phase transition separates a topological phase with non-vanishing anom…
