Optimal schedule of multi-channel quantum Zeno dragging with application to solving the k-SAT problem
Yipei Zhang, Alain Sarlette, Philippe Lewalle +3
The paper analyzes how to optimally schedule multi-channel quantum Zeno dragging—using simultaneous measurements of non‑commuting observables—to drive a quantum system toward a tar…
Towards Heisenberg Scaling: Measurement-Efficient Non-Orthogonal Quantum Eigensolver
Hang Ren, Yipei Zhang, Thilo Scharnhorst +1
The Non-Orthogonal Quantum Eigensolver (NOQE) provides an accurate framework for electronic-structure calculations, but the estimation of its Hamiltonian and overlap matrix element…
Nonasymptotic bounds for quantum purity amplification
Thilo Scharnhorst, Jack Spilecki, John Wright
In quantum purity amplification, one is given copies of a noisy quantum state and asked to prepare copies of its principal eigenstate $|v_d\…
Optimal lower bounds for quantum state tomography
Thilo Scharnhorst, Jack Spilecki, John Wright
We show that copies are necessary to learn a rank mixed state up to error in trace distance. This match…
On the quantum mechanics of entropic forces
Daniel Carney, Manthos Karydas, Thilo Scharnhorst +2
It was conjectured thirty years ago that gravity could arise from the entropic re-arrangement of information. In this paper, we offer a set of microscopic quantum models which real…
