The company says the result is more than four times faster than the previous trapped-ion interconnect record and could support distributed quantum computing.<\/p>\n
The work supports IonQ<\/a>\u2019s participation in DARPA\u2019s HARQ program and builds on commercial quantum networking system sales to the University of Maryland and South Korea\u2019s SDT.<\/p>\n PRESS RELEASE \u2014 IonQ<\/a> (NYSE: IONQ), the world\u2019s leading full-stack quantum platform and foundry, today announced the achievement of entanglement rates above 1,000 per second (1 kHz) between a trapped ion qubit and a solid-state memory, through a photonic interconnect. Entanglement is the quantum connection that lets separate systems work together, and it is the essential ingredient for networking quantum computers. While the trapped ion qubit sets the standard for qubit coherence, the solid-state quantum memory has unmatched efficiency coupling to light. Their juxtaposition is the best of both worlds, demonstrating the fastest quantum interconnect rate between qubits of any platform.<\/p>\n \u201cIonQ<\/a> has crossed a pivotal milestone for memory enhanced quantum interconnects, achieving more than 1,000 entanglement events per second,\u201d said Niccolo de Masi, Chairman and CEO of IonQ. \u201cClassical data centers achieved massive scale by connecting specialized processors, memory, and networks. Quantum systems will scale in much the same way. This breakthrough addresses a critical interconnect bottleneck and advances IonQ\u2019s roadmap to build the networked quantum data centers of the future.\u201d<\/p>\n A technical paper presents results from real-world hardware testing of an end-to-end link between a trapped ion system and a silicon vacancy (SiV) qubit, building on IonQ<\/a>\u2019s SiV quantum memory platform<\/a>. IonQ\u2019s demonstration achieves rates more than four times faster than the previous record1 for trapped ions, held by IonQ co-founder Chris Monroe\u2019s research group at Duke University, also a collaborator on the paper.<\/p>\n \u201cIonQ<\/a>\u2019s efforts in quantum interconnects go back over a decade, to the founding of the company. Moving qubits through photons will be necessary in any large-scale quantum computer, and this demonstration sets the foundation for some amazing work to come,\u201d said Monroe, Chief Scientist at IonQ and Gilhuly Family Presidential Distinguished Professor at Duke University.<\/p>\n \u201cThis work shows that a photonic quantum interconnect need not be a bottleneck for distributed quantum computing,\u201d said Mihir Bhaskar, IonQ<\/a> SVP and GM of Quantum Technologies at SkyWater. \u201cOur technology can interface with almost any qubit type, so we see this unlocking a wide range of opportunities across multiple hardware modalities, from modular computing to networked sensing and beyond.\u201d<\/p>\n This quantum memory and interconnect approach is also driving IonQ<\/a>\u2019s work with the Defense Advanced Research Projects Agency\u2019s (DARPA) HARQ program<\/a>, which seeks to develop high-speed quantum interconnects compatible with multiple computing qubit types. While this latest demonstration used trapped ion systems, the underlying architecture is expected to be compatible with multiple qubit approaches. This may include neutral atoms and superconducting systems with transducers (devices that convert microwave signals into light).<\/p>\n IonQ<\/a>\u2019s memory and interconnect platform is likewise ramping up commercially, with the first commercial sale to the University of Maryland announced<\/a> in April, and a second system sale to SDT in South Korea, announced<\/a> in September.<\/p>\n![\"Introducing](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/10\/1791586933_392_Option-1-1-1.png\")
