Optimal robust single-qubit gates in superconducting quantum processors
Tangyou Huang, Anuj Aggarwal, Jingjun Zhu +11
Fault-tolerant quantum computing requires high-fidelity quantum gates that are resilient to control errors and device imperfections. Here, we develop energy-optimal control pulses…
Classical Shadows with Selective GHZ Measurements
Nicolas Faroß, Marc Wanner, Pingal Pratyush Nath +3
Classical shadows allow the prediction of many quantum-state properties from measurement data, but their efficiency strongly depends on the underlying measurement ensemble. We intr…
Simulation-Based Quantum System Inference with Neural Posterior Estimation
Hang Zou, Anton Frisk Kockum, Martin Rahm +1
Models of quantum systems faithfully map system parameters to observations, but the inverse problem of parameter inference from measurement data presents a fundamental challenge: c…
Cavity magnonics and bound states in the continuum with Bragg and anti-Bragg mirrors
B. -Y. Wu, K. -P. Li, G. Chen +7
A periodic resonant emitter array coupled to a one-dimensional waveguide can act as a mirror. A typical example is a Bragg mirror, where emitters are spaced by multiples of half wa…
Intra-bandgap Bound-State Magnonics in a Photonic Crystal Waveguide
Chong-Xin Run, Xue-Feng Pan, Bang-Yao Wu +5
Cavity and waveguide magnonics have recently emerged as frontiers for investigating light-matter interactions. In these systems, coupling magnons into meticulously engineered photo…
Heuristically optimizing, synthesizing, and prioritizing measurement settings for quantum state tomography
Sumukh S. Moudghalya, Anton Frisk Kockum, Akshay Gaikwad
A key task in many quantum-computing applications, e.g., quantum simulation and quantum state tomography (QST), is to partition an arbitrary set of operators into mutually commutin…
Comparing and learning figures of merit for quantum circuit compilation
Harshdeep Singh, Marvin Richter, Mats Granath +1
To make quantum algorithms executable on a particular quantum device, they need to be compiled into circuits that respect constraints of the quantum hardware. This compilation usua…
Fidelity bounds for adiabatic gates and other quantum operations with time-dependent dissipation
Simon Pettersson Fors, Aniket Patel, Anton Frisk Kockum +1
As quantum-computing platforms are susceptible to noise, the fidelity of quantum operations is limited by decoherence. Understanding this limitation is crucial for building utility…
Forbidden transitions in superconducting artificial atoms
Alberto Del Ángel, Théo Sépulcre, Ricardo Gutiérrez-Jáuregui +1
Artificial atoms built from Josephson junctions have become a powerful tool to explore the limits of quantum optics due to their strong coupling to electromagnetic fields and their…
Driven-dissipative entanglement of distant giant atoms
Aziza Almanakly, Ariadna Soro, Alejandro Vivas-Viaña +15
Quantum interconnects distribute entanglement via controlled light-matter interactions for quantum computing and sensing applications. Many entanglement generation schemes use cohe…
Controlled-Z gates with giant atoms in structured waveguides
Walter Rieck, Ariadna Soro, Anton Frisk Kockum +1
Giant atoms are quantum emitters coupled to waveguides at multiple, spatially separated points, enabling interference effects that fundamentally change their light-matter interacti…
