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…
On the Rational Degree of Boolean Functions and Applications
Vishnu Iyer, Siddhartha Jain, Robin Kothari +5
We study a natural complexity measure of Boolean functions known as the rational degree. Denoted , it is the minimal degree of a rational function that is equal t…
Quantum Communication Advantage in TFNP
Mika Göös, Tom Gur, Siddhartha Jain +1
We exhibit a total search problem with classically verifiable solutions whose communication complexity in the quantum SMP model is exponentially smaller than in the classical two-w…
