DARPA Awards PsiQuantum $125M for Quantum Computing Benchmarking

PsiQuantum has landed a $125 million contract from DARPA, the US defense research agency, to test its utility-scale quantum computing technology under the Quantum Benchmarking Initiative, marking the company’s largest government agreement to date.

The $125 million contract, part of DARPA’s Quantum Benchmarking Initiative (QBI), aims to rigorously evaluate PsiQuantum’s photonic-based approach to building a fault-tolerant quantum computer. DARPA is assessing whether any quantum computing technology can achieve utility-scale operation by 2035, and PsiQuantum claims its silicon photonics platform can deliver commercially viable systems on an accelerated timeline. This funding follows a previous engagement with DARPA and underscores growing federal investment in quantum technology, viewed as critical for national security and economic competitiveness.

For the electronics manufacturing industry, quantum computing represents a new frontier for high-density interconnect (HDI) and IC substrate PCBs. These systems require extreme signal integrity, low-loss materials, and complex multilayer designs to handle cryogenic and high-speed operations. As DARPA pushes quantum hardware closer to reality, PCB/PCBA suppliers must prepare for novel requirements, from advanced thermal management to ultra-fine line patterning.

LT CIRCUIT provides HDI, IC substrate, and advanced multilayer PCBs suitable for quantum computing applications. Our manufacturing capabilities align with the high-reliability demands of next-generation computing hardware.
