How large does a useful quantum computer need to be?

This is an important but surprisingly hard question to answer.

PsiQuantum to start installation of its cryogenic quantum modules, each containing photonic quantum hardware, into SLAC’s LCLS-II cryoplant facility, capable of kilowatts of cooling power. This partnership accelerates the development and testing of this novel technology while also defining opportunities for further collaboration in the future.

Cracking cryptographic protocols is a well-known impact area for fault-tolerant quantum computing. Clearly it is important to estimate just when quantum computers will impact cryptography.

There’s an unsung impasse currently facing commercially useful fault-tolerant quantum computers. Useful quantum computers rely on quantum error-correcting codes that redundantly encode otherwise delicate logical information into a much larger system of physical qubits….

Quantum computing has the potential to drive the major breakthroughs needed to help solve the climate crisis. Jeremy O’Brien, a pioneer in the field, shares how PsiQuantum is seeking to harness quantum computing for large-scale climate-change mitigation.

Dr Sam Roberts, Quantum Architect at PsiQuantum and University of Sydney PhD alumni, long had a passion for abstract maths, and thought he’d end up teaching it at university. Instead, he’s pushing the limits of linear algebra to encode data into particles of light. Read about what motivated him to pursue a career in quantum computing.

PsiQuantum is Hitting on All Cylinders – Not least because of a $25 million award as part of the recently passed U.S. FY2022 package… PsiQuantum also reported an improved approach to simulating chemical systems in a paper co-authored with Mercedes-Benz R&D and published in APS’s Physical Review Research. PsiQuantum said “a new analysis of how electrolyte molecules in Lithium-ion batteries (LiB) can be simulated on a fault-tolerant quantum computer, enabling breakthroughs sought by automotive manufacturers in next-generation battery design.”
