Fidelity estimation of quantum states on a silicon photonic chip
Sabine Wollmann, Xiaogang Qiang, Sam Pallister +3
As a measure of the 'closeness' of two quantum states, fidelity plays a fundamental role in quantum information theory. Fidelity estimation protocols try to strike a balance betwee…
Quantum majority vote
Harry Buhrman, Noah Linden, Laura Mančinska +2
Majority vote is a basic method for amplifying correct outcomes that is widely used in computer science and beyond. While it can amplify the correctness of a quantum device with cl…
How to use arbitrary measuring devices to perform almost perfect measurements
Noah Linden, Paul Skrzypczyk
We consider the problem of reproducing one quantum measurement given the ability to perform another. We give a general framework and specific protocols for this problem. For exampl…
Average-Case Verification of the Quantum Fourier Transform Enables Worst-Case Phase Estimation
Noah Linden, Ronald de Wolf
The quantum Fourier transform (QFT) is a key primitive for quantum computing that is typically used as a subroutine within a larger computation, for instance for phase estimation.…
Integrable spin chains and the Clifford group
Nick G. Jones, Noah Linden
We construct new families of spin chain Hamiltonians that are local, integrable and translationally invariant. To do so, we make use of the Clifford group that arises in quantum in…
Quantum-accelerated multilevel Monte Carlo methods for stochastic differential equations in mathematical finance
Dong An, Noah Linden, Jin-Peng Liu +3
Inspired by recent progress in quantum algorithms for ordinary and partial differential equations, we study quantum algorithms for stochastic differential equations (SDEs). Firstly…
