IBM today issued an extensive and detailed expansion of its Quantum Roadmap that calls for developing a new 1386-qubit processor – Kookaburra – built from modularly scaled chips, and delivering a 4,158-qubit POC system built using three connected Kookaburra processors by 2025. Kookaburra (Australian Kingfisher) is a new architecture... Read more…

PsiQuantum, founded in 2016 by four researchers with roots at Bristol University, Stanford University, and York University, is one of a few quantum computing startups that’s kept a moderately low PR profile. (That’s if you disregard the roughly $700 million in funding it has attracted.) The main reason is PsiQuantum has eschewed the clamorous public chase for... Read more…

Thanks to Planck’s constant — 4.14 x 10-15 eV seconds, rounded up (or 6.63 x 10-34 Joule seconds, if you prefer) — April 14 has been designated World Quantum Day by a loosely affiliated group of scientists and organizations around the world, including the U.S. (see website). The broad idea is to spotlight quantum information science’s rapid growth and, in particular... Read more…

Building the quantum information sciences (QIS) industry — or more accurately, helping it build itself — is Celia Merzbacher’s job as executive director of the Quantum Economic Development Consortium (QED-C). The QED-C was brought into being with the 2018 National Quantum Initiative Act and is broadly overseen by NIST and the National Quantum... Read more…

At yesterday’s Quantum in Industry session at the APS March Meeting 2022, Google, IBM, Intel, Quantinuum, and Silicon Quantum Computing/University of South Wales (USW) presented progress points and ongoing challenges in the race to achieve practical quantum computing. While IBM has proclaimed 2023 to be the year it achieves quantum advantage, the other... Read more…

It’s been a busy week in quantum computing. Rigetti began providing much wider access to its 80-qubit system (Aspen-M), announced a collaboration with Nasdaq to develop FS apps, and struck a deal with Arm-based chip supplier Ampere to develop hybrid classical-quantum platforms. Elsewhere, JPMorgan Chase, Toshiba, and Ciena reported successfully... Read more…
