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.

Fusion based quantum computation (FBQC) is designed to implement fault-tolerant quantum computing with the photonic hardware used at PsiQuantum…

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.
