  • Variational Processing of Multimode Squeezed Light

    Author(s): Aviv Karnieli, Paul-Alexis Mor, Charles Roques-Carmes, Eran Lustig, Jamison Sloan, Jelena Vučković, David A.B. Miller, and Shanhui Fan By variationally identifying the most strongly squeezed supermodes, researchers compress multimode photonic processors from quadratic scaling to a near-constant hardware footprint.

  • High-Threshold, Low-Overhead and Single-Shot Decodable Fault-Tolerant Quantum Memory

    Author(s): Thomas R. Scruby, Timo Hillmann, and Joschka Roffe Radial codes, a new class of low-density parity-check codes with strong error correction capabilities, tunable parameters, and small size, are shown to be a promising candidate for near-term quantum devices.

  • Overhead in Quantum Circuits with Time-Multiplexed Qubit Control

    Author(s): Marvin Richter, Ingrid Strandberg, Simone Gasparinetti, and Anton Frisk Kockum Scaling quantum processors via shared control lines is more efficient than expected, with serialization costs scaling only logarithmically and posing no overhead for certain two-qubit gate configurations.

  • Quantum-Network Nodes with Real-Time Noise Mitigation Using Spectator Qubits

    Author(s): S.J.H. Loenen, Y. Wang, N. Demetriou, C.E. Bradley, and T.H. Taminiau Experimental demonstration of noise monitoring via readily available qubits presents a low-cost approach for counteracting errors caused by entanglement distribution across network nodes.
