Mechanically induced correlated errors on superconducting qubits with relaxation times exceeding 0.4 ms
Tobias Kippenberg, Amir Youssefi, Marco Scigliuzzo, Mahdi Chegnizadeh, Shingo Kono, Xuxin Wang
Superconducting qubits are among the most advanced candidates for achieving fault-tolerant quantum computing. Despite recent significant advancements in the qubit lifetimes, the origin of the loss mechanism for state-of-the-art qubits is still subject to i ...
Nature Portfolio2024Femtosecond-laser direct-write photoconductive patterns on tellurite glass
Yves Bellouard, Gözden Torun, Anastasia Romashkina
We report the formation of arbitrary photoconductive patterns made of tellurium (Te) nanocrystals by exposing a tellurite (TeO2-based) glass to femtosecond laser pulses. During this process, Te/TeO2-glass nanocomposite interfaces with photoconductive prope ...
2024Wavelength-stabilized figure-of-9 thulium-doped all-fiber laser emitting 560 fs pulses
Camille Sophie Brès, Moritz Bartnick, Gayathri Bharathan
We demonstrate a figure-of-9 all-fiber thulium-doped laser (TDFL) that generates 560 fs long pulses at 1948 nm wavelength. In order to achieve self-starting passive mode-locking, we utilize an in-fiber Faraday rotator to induce a nonreciprocal phase shift. ...
Bristol2024Error field detection and correction studies towards ITER operation
Olivier Sauter, Bernhard Sieglin, Leonardo Pigatto
In magnetic fusion devices, error field (EF) sources, spurious magnetic field perturbations, need to be identified and corrected for safe and stable (disruption-free) tokamak operation. Within Work Package Tokamak Exploitation RT04, a series of studies hav ...
Iop Publishing Ltd2024Overhead-constrained circuit knitting for variational quantum dynamics
Giuseppe Carleo, Gian Florin Gentinetta, Friederike Metz
Simulating the dynamics of large quantum systems is a formidable yet vital pursuit for obtaining a deeper understanding of quantum mechanical phenomena. While quantum computers hold great promise for speeding up such simulations, their practical applicatio ...

Spie-Int Soc Optical Engineering2024Progress in the development of the ITER baseline scenario in TCV
Olivier Sauter, Stefano Coda, Benoît Labit, Alessandro Pau, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Oleg Krutkin, Cassandre Ekta Contré, Reinart Andreas J. Coosemans, Stefano Marchioni, Yann Camenen, Matteo Vallar, Filippo Bagnato, Simon Van Mulders
Under the auspices of EUROfusion, the ITER baseline (IBL) scenario has been jointly investigated on AUG and TCV in the past years and this paper reports on the developments on TCV. It is found that the performance of TCV IBL is mainly limited by (neoclassi ...
2024Empirical Sample Complexity of Neural Network Mixed State Reconstruction
Giuseppe Carleo, Filippo Vicentini, Haimeng Zhao
Quantum state reconstruction using Neural Quantum States has been proposed as a viable tool to reduce quantum shot complexity in practical applications, and its advantage over competing techniques has been shown in numerical experiments focusing mainly on ...
