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…
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…
Topological state permutations in time-modulated non-Hermitian multiqubit systems with suppressed non-adiabatic transitions
Ievgen I. Arkhipov, Philippe Lewalle, Franco Nori +2
Non-Hermitian systems have been at the center of intense research for over a decade, partly due to their nontrivial energy topology formed by intersecting Riemann manifolds with br…
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…
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…
Real-time propagation of adaptive sampling selected configuration interaction wave function
Avijit Shee, Zhen Huang, Martin Head-Gordon +1
We have developed a new time propagation method, time-dependent adaptive sampling configuration interaction (TD-ASCI), to describe the dynamics of a strongly correlated system. We…
