Reduced scaling implementation of the coupled cluster-based static embedding method, MPCC with density fitting
Avijit Shee, Fabian M. Faulstich, K. Birgitta Whaley +2
An improved algorithm to implement our previously proposed static quantum embedding method MPCC (J. Chem. Phys. 161, 164107 (2024)) is presented. It uses the density-fitting (DF) a…
Consistent inclusion of triple substitutions within a coupled cluster based static quantum embedding theory
Avijit Shee, Fabian M. Faulstich, K. Birgitta Whaley +2
We incorporate a solver for the fragment problem with accuracy beyond coupled cluster singles and doubles (CCSD) into the previously proposed static embedding framework, MPCC. To t…
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…
Beyond real: Alternative unitary cluster Jastrow models for molecular electronic structure calculations on near-term quantum computers
Nikolay V. Tkachenko, Hang Ren, Wendy M. Billings +3
Near-term quantum devices require wavefunction ansätze that are expressive while also of shallow circuit depth in order to both accurately and efficiently simulate molecular electr…
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…
