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. However, this is a technically challenging task, involving careful evaluation of the resources needed by quantum algorithms in light of numerous architectural and hardware specific considerations.
We recently announced a new approach to vastly increasing the efficiency of running quantum algorithms. We call it the Active Volume Architecture. The key insight is that if you have access to certain hardware capabilities then you can obtain remarkable reductions in the running costs of commercially useful quantum algorithms (for example, reducing running costs by around 50x for factoring algorithms).
Fusion based quantum computation (FBQC) is designed to implement fault-tolerant quantum computing with the photonic hardware used at PsiQuantum. By efficiently using native operations this approach can be more robust against errors, allowing it to tolerate approximately five times more photon loss compared to previous photonic architectures. Importantly, the approach is modular, which means it can be scaled across multiple machines without a significant loss of performance.
Over the past three decades significant reductions have been made to the cost of estimating ground-state energies of molecular Hamiltonians with quantum computers. However, comparatively little attention has been paid to estimating the expectation values of other observables with respect to said ground states, which is important for many industrial applications.

The widespread adoption of electric vehicles rests on developing faster charging, longer lasting battery technology – the critical enabler for transitioning away from internal combustion engines. PsiQuantum has been working with Mercedes Benz to assess just how advanced a quantum computer must be to revolutionize Lithium-ion (Li-ion) battery design.
Jeremy O’Brien, CEO and Co-Founder of PsiQuantum, delivers a keynote a the Sydney Quantum Academy’s Quantum Australia Conference 2023 with a focus on PsiQuantum’s recent technical progress on its mission to deliver the world’s first fault tolerant quantum computer.
