Quantum Art extends Series A to $140M total with Hudson Bay, Poalim Equity, and others joining Bedford Ridge Capital lead
On 2026-04-27, Quantum Art — an Israeli trapped-ion quantum computing company spun out of the Weizmann Institute of Science in 2022 — announced a Series A extension that brings the round's cumulative size to $140M. The original $100M Series A closed in December 2025, led by Bedford Ridge Capital. The 2026-04-27 extension adds approximately $40M of fresh capital and lists Hudson Bay Capital, Poalim Equity, LIP Ventures, Wolverine Global Ventures, and IDA Ventures as new participants. The company stated proceeds will fund development of Perspective — a 1,000-qubit multi-core trapped-ion system — alongside advanced optics for qubit scaling and an internal 2D-architecture roadmap. Quantum Art's distinguishing claim is a multi-core architecture in which lasers slice a long ion chain into independently controllable cores and shift ions between cores in microseconds, preserving any-to-any reachability along the chain.
Series A extension at a tracked-eligible private trapped-ion company, bringing Series A cumulative to $140M with a sophisticated multi-asset-manager investor mix (Hudson Bay Capital, Poalim Equity). Score 5 per the §8.2 anchor for a Series A/B funding round at a non-officer-cluster, non-strategic-milestone-disclosed funding event: the increment is below the $50M-fresh-cash threshold that would push a follow-on to score 6, no specific qubit-count milestone is claimed at this announcement, and the 1,000-qubit Perspective target remains aspirational. Conservative score per the close-call-rounds-down rule.
Sets a 2026 trapped-ion private-financing comparable for IonQ's competitor set (Atom Computing's H1 2026 round, AOSense, Universal Quantum) and establishes Hudson Bay Capital — a multi-strategy hedge fund historically active in Israeli pre-IPO crossover positions — as a quantum-sector investor; that name overlap raises the probability of a future crossover round if Quantum Art's 1,000-qubit Perspective hits a fabrication or coherence milestone.
