美国战争部1.5亿美元贷款力挺量子计算：光子路线公司 PsiQuantum 获承诺
美国战争部战略资本办公室周四宣布，向量子计算公司 PsiQuantum 提供最高 1.5 亿美元的有条件贷款承诺，用于提升其在美国本土的先进制造与原型能力。这是五角大楼 3.5 亿美元量子计算计划的一部分。 PsiQuantum 走的是光子量子计算路线，目标是造出全球第一台可商用的容错量子计算机。它此前已获国防高级研究计划局（DARPA）"量子基准计划"支持，并与商务部签下 1 亿美元的芯片法案相关协议。战略资本办公室主任洛奇表示，这笔交易是落实总统关于美国领跑量子信息科技的要求；公司高管则称，容错量子计算关乎国家安全。 "有条件"意味着钱还没到账：公司须先通过财务、法律、技术与尽职调查等常规关卡，贷款才能正式落地。（据美国战争部公告）
War Department's $150M Loan Commitment Backs PsiQuantum's Photonic Quantum Push
The U.S. Department of War's Office of Strategic Capital announced Thursday a conditional loan commitment of up to $150 million to PsiQuantum, to expand the company's advanced manufacturing and prototyping capabilities in the United States. The commitment is part of the Pentagon's $350 million quantum computing initiative. PsiQuantum is pursuing photonic quantum computing, aiming to build the world's first commercially useful fault-tolerant quantum computer. It previously won support under DARPA's Quantum Benchmarking Initiative and signed a $100 million CHIPS-related agreement with the Commerce Department. OSC Director David A. Lorch said the deal executes the president's mandate for U.S. leadership in quantum information science; company executives called fault-tolerant quantum computing a national-security imperative. "Conditional" means no money has moved yet: the company must still clear customary financial, legal, technical and due-diligence steps before the loan can close.
