This computer could solve problems in seconds that traditional computers would take millions of years to solve. ## Cooling Systems The computer will be housed in hundreds of steel cabinets cooled by liquid helium. This system ensures the stability of quantum bits. ## Power of Quantum Bits Quantum bits can exist in multiple states simultaneously. This feature significantly enhances the computer's computational power. ## Medical Research PsiQuantum aims to predict how drugs interact in the body more quickly. This could significantly accelerate the drug development process. ## Investment and Support The company raised $1 billion in funding last year and began constructing a facility in Chicago. This facility will be the production hub for the quantum computer. ## Semiconductor Factories PsiQuantum is building its systems using existing semiconductor factories. This reduces costs while increasing production speed. ## Government Evaluation The company has reached the third stage of the government's intensive evaluation program. This demonstrates PsiQuantum's potential for success. ## Quantum Mechanics Quantum computers can model the behavior of subatomic particles. This could revolutionize many areas of modern science. ## Schrödinger's Legacy PsiQuantum co-founder Terry Rudolph is the grandson of the famous physicist Erwin Schrödinger. This legacy shapes the company's vision. ## Technology of the Future Quantum computers could have a significant impact in fields ranging from medicine to engineering. PsiQuantum is building this future now. ## Challenges and Opportunities Developing a quantum computer involves significant challenges. However, if successful, this technology could change the world. ## Conclusion and Importance PsiQuantum's work could shape the future of quantum computers. This could be a step that pushes the boundaries of technology. ## Sources covering this story - https://www.technologyreview.com/2026/07/14/1140356/psiquantum-plan-massive-quantum-computer-out-of-light/ — --- _Summary written by Brifing from the original reporting.
