Fault-tolerant distributed quantum computing with a single nucleus per node
Yotam Vaknin, Shoham Jacoby, Shoham Jaocby +3
Distributed quantum computing interconnects small, high-quality nodes through optical links, but this architecture carries a pronounced asymmetry: in-node gates and measurements ar…
PIQC: Scalable Distributed Quantum Computing via Photonic Integration of Designed Molecular Quantum Nodes
Anna Aubele, Gregor Bayer, Tim R. Eichhorn +16
There is a growing consensus that large-scale, fault-tolerant quantum computing (FTQC) necessitates high-fidelity photonic interconnects to overcome the scaling limits of monolithi…
Fast, High-Fidelity Erasure Detection of Dual-Rail Qubits with Symmetrically Coupled Readout
Jimmy Shih-Chun Hung, Arbel Haim, Mouktik Raha +14
Erasure qubits are a promising platform for implementing hardware-efficient quantum error correction. Realizing the error-correction advantages of this encoding requires frequent m…
Fast measurement of neutral atoms with a multi-atom gate
Yotam Vaknin, Ran Finkelstein, Ofer Firstenberg +1
Measurement time represents a critical bottleneck limiting the operational speed of neutral atom quantum computers, as it cannot be accelerated through parallelization like other q…
Readout-induced degradation of transmon lifetimes: interplay of TLSs and qubit spectral reshaping
Ziwen Huang, Jimmy Shih-Chun Hung, Mouktik Raha +9
Measurement backaction degrades dispersive readout of superconducting qubits even at modest drive strengths, often via the reduction of qubit lifetimes during readout. In this work…
Optimal quantum metrology protocols with erasure qubits
Michal Arieli, Alex Retzker, Tuvia Gefen
We investigate the precision limits and optimal protocols for sensing single qubit signals in the presence of erasure noise. We study a hierarchy of precision limits achievable wit…
