Tight bounds on the simultaneous estimation of incompatible parameters
Jasminder S. Sidhu, Yingkai Ouyang, Earl T. Campbell +1
The estimation of multiple parameters in quantum metrology is important for a vast array of applications in quantum information processing. However, the unattainability of fundamen…
Compilation by stochastic Hamiltonian sparsification
Yingkai Ouyang, David R. White, Earl T. Campbell
Simulation of quantum chemistry is expected to be a principal application of quantum computing. In quantum simulation, a complicated Hamiltonian describing the dynamics of a quantu…
Robust quantum metrology with explicit symmetric states
Yingkai Ouyang, Nathan Shettell, Damian Markham
Quantum metrology is a promising practical use case for quantum technologies, where physical quantities can be measured with unprecedented precision. In lieu of quantum error corre…
Quantum storage in quantum ferromagnets
Yingkai Ouyang
We must protect inherently fragile quantum data to unlock the potential of quantum technologies. A pertinent concern in schemes for quantum storage is their potential for near-term…
Homomorphic encryption of linear optics quantum computation on almost arbitrary states of light with asymptotically perfect security
Yingkai Ouyang, Si-Hui Tan, Joseph Fitzsimons +1
Future quantum computers are likely to be expensive and affordable outright by few, motivating client/server models for outsourced computation. However, the applications for quantu…
Faster quantum computation with permutations and resonant couplings
Yingkai Ouyang, Yi Shen, Lin Chen
Recently, there has been increasing interest in designing schemes for quantum computations that are robust against errors. Although considerable research has been devoted to develo…
