Optimal testing of fermionic and bosonic Gaussian states

Vishnu Iyer, Bryan O'Gorman, Ojas Parekh +2

We study the problem of property testing quantum states: given a pure state $∣ ψ ⟩$ that either (A) belongs to some class $C$ of pure states, or (B) is $ε$ -far in tra…

Efficient quantum circuits for high-dimensional representations of SU(n) and Ramanujan quantum expanders

Vishnu Iyer, Siddhartha Jain, Stephen Jordan +1

We present efficient quantum circuits that implement high-dimensional unitary irreducible representations (irreps) of $S U (n)$ , where $n \geq 2$ is constant. For dimension $N$ and er…
