Quantum Fanout and GHZ states using spin-exchange interactions
Stephen Fenner, Rabins Wosti
We show how the fanout operation on logical qubits can be implemented via spin-exchange (Heisenberg) interactions between physical qubits, together with a physical target…

Optimal lower bound for lossless quantum block encoding
George Androulakis, Rabins Wosti
Consider a general quantum stochastic source that emits at discrete time steps quantum pure states which are chosen from a finite alphabet according to some probability distributio…
