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 that either (A) belongs to some class of pure states, or (B) is -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 , where is constant. For dimension and er…
Efficient Quantum Hermite Transform
Siddhartha Jain, Vishnu Iyer, Rolando D. Somma +2
We present a new primitive for quantum algorithms that implements a discrete Hermite transform efficiently, in time that depends logarithmically in both the dimension and the inver…
Fermionic Insights into Measurement-Based Quantum Computation: Circle Graph States Are Not Universal Resources
Brent Harrison, Vishnu Iyer, Ojas Parekh +2
Measurement-based quantum computation (MBQC) is a strong contender for realizing quantum computers. A critical question for MBQC is the identification of resource graph states that…
Efficient learning of bosonic Gaussian unitaries
Marco Fanizza, Vishnu Iyer, Junseo Lee +2
Bosonic Gaussian unitaries are fundamental building blocks of central continuous-variable quantum technologies such as quantum-optic interferometry and bosonic error-correction sch…
