Two Paths to Scalable Quantum Computing: Optical Links Between Fridges and Higher-Temperature Qubits
Researchers led by Prof. Hong Tang reported two advances that could unlock large‑scale quantum computers. First, they built an electro‑optic transducer that converts microwave qubit signals to optical photons, enabling a 1‑km fiber link between separate dilution refrigerators without cryogenic cables. Second, they used atomic‑layer deposition to fabricate NbN/AlN/NbN superconducting qubits that operate around 13 K, far above the 1 K limit of aluminum‑based devices. Both approaches aim to reduce cooling overhead and simplify the wiring needed for millions of qubits.
Ripple Wants the XRP Ledger to Be Quantum-Proof by 2028. Here Is Its Plan
Ripple announced a four‑phase roadmap to make the XRP Ledger quantum‑resistant by 2028. The plan starts with an emergency “Q‑day readiness” phase that would require all funds to move to quantum‑safe accounts and enable recovery via zero‑knowledge proofs. Subsequent phases...
A Long-Sought Quantum Computing Milestone Arrives as Fermionic Atom Gates Top 99% Accuracy
Two independent teams at the Max Planck Institute and ETH Zurich have demonstrated collisional quantum gates using fermionic lithium‑6 atoms, achieving two‑qubit gate fidelities above 99 %. Bojović’s group reported a peak accuracy of 99.75 %, while Kiefer’s team reached a loss‑corrected...
Beyond Qubits: A Systems View of Hybrid CV-DV Quantum Computing
At ASPLOS 2026 a tutorial introduced hybrid continuous‑discrete‑variable (CV‑DV) quantum computing, which treats qubits and oscillator modes as a unified computational resource. The session covered the physical foundations, new instruction set architectures, and the compilation stack that translates high‑level algorithms...
Quantum Computing and Storage
OVHcloud has added Quantum Computing‑as‑a‑Service (QaaS) by offering Quandela’s 12‑qubit Belanos photonic quantum computer on a pay‑as‑you‑go basis. The quantum processor works alongside OVH’s traditional object storage, with data encoded into photonic states before each run and results post‑processed on...
