- Abstract: We propose a methodology to emulate quantum phenomena arising from any
non-classical quantum state using only a finite set of mixtures of coherent
states. This allows us to successfully reproduce well-known quantum effects
using resources that can be much more feasibly generated in the laboratory. We
present a simple procedure to experimentally carry out quantum-state emulation
with coherent states, illustrate it emulating multi-photon NOON states with few
phase-averaged coherent states, and demonstrate its capabilities in observing
fundamental quantum-mechanical effects, such as the Hong-Ou-Mandel effect,
violating Bell inequalities and witnessing quantum non-classicality.

We introduce a quantum hardness assumption called the Hamiltonian Phase State (HPS) problem.
We show that our assumption is plausibly fully quantum; meaning, it cannot be used to construct one-way functions.
We show that our assumption and its variants allow us to efficiently construct many pseudorandom quantum primitives.
