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…
Noise-Canceling Quantum Feedback: non-Hermitian Dynamics with Applications to State Preparation and Magic State Distillation
Tathagata Karmakar, Philippe Lewalle, Yipei Zhang +1
Time-continuous quantum measurement allows for the tracking of a quantum system in real time via sequences of short, and individually weak, measurement intervals. Such measurements…
Optimal schedule of multi-channel quantum Zeno dragging with application to solving the k-SAT problem
Yipei Zhang, Alain Sarlette, Philippe Lewalle +3
Quantum Zeno dragging enables the preparation of common eigenstates of a set of observables by frequent measurement and adiabatic-like modulation of the measurement basis. In this…
An Error Mitigated Non-Orthogonal Quantum Eigensolver via Shadow Tomography
Hang Ren, Yipei Zhang, Wendy M. Billings +4
We present a shadow-tomography-enhanced Non-Orthogonal Quantum Eigensolver (NOQE) for more efficient and accurate electronic structure calculations on near-term quantum devices. By…
Solving k-SAT problems with generalized quantum measurement
Yipei Zhang, Philippe Lewalle, K. Birgitta Whaley
We generalize the projection-based quantum measurement-driven -SAT algorithm of Benjamin, Zhao, and Fitzsimons (BZF, arxiv:1711.02687) to arbitrary strength quantum measurements…
