Our quantum algorithms are delivering meaningful results today, and we&#8217;re excited to join the impressive QBI team.&#8221;<\/p>\n<p>If Phasecraft&#8217;s algorithms show that key applications require fewer logical qubits than previously thought, it could change the US government&#8217;s investment strategy in quantum technology.<\/p>\n<p>The company works with leading hardware firms including Google Quantum AI, IBM, Quantinuum and QuEra.<\/p>\n<p>Phasecraft was founded in 2019 by Montanaro, Prof Toby Cubitt and Prof John Morton, quantum scientists from UCL and the University of Bristol.<\/p>\n<p>The contract follows the company&#8217;s recent $34m Series B funding round, which brought total investment to over $50m including grant and contract funding.<\/p>\n<p>In October, Phasecraft launched Mondrian, a quantum-enhanced software platform designed to speed up classical optimisation algorithms for industries including energy, finance and logistics.<\/p>\n<p>The company will work as a technical expert on a contract led by the University of Maryland&#8217;s Applied Research Laboratory for Intelligence and Security to support DARPA&#8217;s benchmarking initiative.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phasecraft&#8217;s algorithms will inform Defence investment strategy<\/p>\n","protected":false},"author":26,"featured_media":32973,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[120785,50204],"coauthors":[160],"class_list":["post-36917","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-international","category-technology","tag-bristol-and-bath","tag-featured-story"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.9 -
