Scalable tensor-network error mitigation for near-term quantum computing
Sergei Filippov, Matea Leahy, Matteo A. C. Rossi +1
Until fault-tolerance becomes implementable at scale, quantum computing will heavily rely on noise mitigation techniques. While methods such as zero noise extrapolation with probab…
Daemonic ergotropy in continuously-monitored open quantum batteries
Daniele Morrone, Matteo A. C. Rossi, Marco G. Genoni
The amount of work that can be extracted from a quantum system can be increased by exploiting the information obtained from a measurement performed on a correlated ancillary system…
Matrix product channel: Variationally optimized quantum tensor network to mitigate noise and reduce errors for the variational quantum eigensolver
Sergey Filippov, Boris Sokolov, Matteo A. C. Rossi +5
Quantum processing units boost entanglement at the level of hardware and enable physical simulations of highly correlated electron states in molecules and intermolecular chemical b…
Charging a quantum battery in a non-Markovian environment: a collisional model approach
Daniele Morrone, Matteo A. C. Rossi, Andrea Smirne +1
We study the effect of non-Markovianity in the charging process of an open-system quantum battery. We employ a collisional model framework, where the environment is described by a…
Self-consistent quantum measurement tomography based on semidefinite programming
Marco Cattaneo, Matteo A. C. Rossi, Keijo Korhonen +4
We propose an estimation method for quantum measurement tomography (QMT) based on semidefinite programming (SDP), and discuss how it may be employed to detect experimental imperfec…
Mitigating the measurement overhead of ADAPT-VQE with optimised informationally complete generalised measurements
Anton Nykänen, Matteo A. C. Rossi, Elsi-Mari Borrelli +2
ADAPT-VQE stands out as a robust algorithm for constructing compact ansätze for molecular simulation. It enables to significantly reduce the circuit depth with respect to other met…
