On Scalable Pseudorandom Unitaries and the Unitary Synthesis Problem
The paper establishes a strong connection between scalable pseudorandom unitaries (PRUs) and the unitary synthesis problem, proving that any such PRU construction must require a classical oracle of significant input size, thereby ruling out existing scalable candidates.
How To Track Qubits Through Space and Time (Or: Sailing in a Quantum Boat)
