Kavli Affiliate: Cees Dekker | Summary:Synchronization plays a crucial role in the dynamics of living organisms, from fireflies flashing in unison to pacemaker cells that jointly generate heartbeats. Uncovering the mechanism behind these phenomena requires an understanding of individual biological oscillators and the coupling forces between them. Here, we develop a single-cell assay that studies […]
Kavli Affiliate: Eliska Greplova | Summary:Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity introduces significant challenges in device tuning and control. Here, we demonstrate autonomous tuning of emergent Poor Man’s Majorana zero modes in a minimal realization of a […]

Kavli Affiliate: Viatcheslav Dobrovitski | Summary:Progress in fabrication of semiconductor and superconductor qubits has greatly diminished the number of decohering defects, thus decreasing the devastating low-frequency $1/f$ noise and extending the qubits’ coherence times (dephasing time $T_2^*$ and the echo decay time $T_2$). However, large qubit-to-qubit variation of the coherence properties remains a problem, making […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Diana Marin, Filippo Maggioli, Simone Melzi, Stefan Ohrhallinger, Michael Wimmer | Summary: Reconstructing 2D curves from sample points has long been a critical challenge in computer graphics, finding essential applications in vector graphics. The design and editing of curves on surfaces has only recently begun to receive […]
Kavli Affiliate: Wolfgang Tittel | Summary:We report on a quantum interface linking a diamond NV center quantum network node and 795nm photonic time-bin qubits compatible with Thulium and Rubidium quantum memories. The interface makes use of two-stage low-noise quantum frequency conversion and waveform shaping to match temporal and spectral photon profiles. Two-photon quantum interference shows […]
Kavli Affiliate: Giordano Scappucci | Summary:Addressing and mitigating decoherence sources plays an essential role in the development of a scalable quantum computing system, which requires low gate errors to be consistently maintained throughout the circuit execution. While nuclear spin-free materials, such as isotopically purified silicon, exhibit intrinsically promising coherence properties for electron spin qubits, the […]
Kavli Affiliate: Leonardo Dicarlo | Summary:Quantum error correction enables the preservation of logical qubits with a lower logical error rate than the physical error rate, with performance depending on the decoding method. Traditional error decoding approaches, relying on the binarization (`hardening’) of readout data, often ignore valuable information embedded in the analog (`soft’) readout signal. […]

Yu, Alexander Ivlev | Summary: Qubits that can be efficiently controlled are pivotal in the development of scalable quantum hardware. Resonant control is commonly embraced to execute high-fidelity quantum gates but demands integration of high-frequency oscillating signals and results […]
