Feedback-based quantum optimization.
Proposed for presentation at the 25th Annual Conference on Quantum Information Processing in ,, 2022 It is hoped that quantum computers will offer advantages over classical computers for combinatorial optimization. Here, we introduce a feedback-based strategy for quantum optimization, where the results of qubit measurements are used to constructively assign values to quantum circuit parameters. We show that this procedure results in an estimate of the

Constructing elliptic curve isogenies in quantum subexponential time
Journal of Mathematical Cryptology, 2014 Given two ordinary elliptic curves over a finite field having the same cardinality and endomorphism ring, it is known that the curves admit a nonzero isogeny between them, but finding such an isogeny is believed to be computationally difficult.

Optimizing the optimizer: decomposition techniques for quantum annealing [PDF]
Quantum Machine Intelligence, 2021 Although quantum computing hardware has evolved significantly in recent years, spurred by increasing industrial and government interest, the size limitation of current generation quantum computers remains an obstacle when applying these devices to relevant, real-world problems. In order to effectively exploit the potential benefits of quantum computing,

Floating point representations in quantum circuit synthesis
New Journal of Physics, 2013 We provide a non-deterministic quantum protocol that approximates the single qubit rotations R _x (2 ϕ ^2 _1 ϕ ^2 _2 ) using R _x (2 ϕ _1 ) and R _x (2 ϕ _2 ) and a constant number of Clifford and T operations.

Quantum Optimal Transport is Cheaper [PDF]
Journal of Statistical Physics, 2020 We compare bipartite (Euclidean) matching problems in classical and quantum mechanics. The quantum case is treated in terms of a quantum version of the Wasserstein distance introduced in [F. Golse, C. Mouhot, T. Paul, Commun. Math. Phys. 343 (2016), 165-205]. We show that the optimal quantum cost can be cheaper than the classical one.
