Photonic Quantum Policy Learning in OpenAI Gym
Dániel Nagy, Zsolt Tabi, Péter Hága +2
In recent years, near-term noisy intermediate scale quantum (NISQ) computing devices have become available. One of the most promising application areas to leverage such NISQ quantu…
Modeling and mitigation of cross-talk effects in readout noise with applications to the Quantum Approximate Optimization Algorithm
Filip B. Maciejewski, Flavio Baccari, Zoltán Zimborás +1
We introduce a correlated measurement noise model that can be efficiently described and characterized, and which admits effective noise-mitigation on the level of marginal probabil…
Quantum Optimization for the Graph Coloring Problem with Space-Efficient Embedding
Zsolt Tabi, Kareem H. El-Safty, Zsófia Kallus +4
Current quantum computing devices have different strengths and weaknesses depending on their architectures. This means that flexible approaches to circuit design are necessary. We…
Space-efficient binary optimization for variational computing
Adam Glos, Aleksandra Krawiec, Zoltán Zimborás
In the era of Noisy Intermediate-Scale Quantum (NISQ) computers it is crucial to design quantum algorithms which do not require many qubits or deep circuits. Unfortunately, the mos…
Mitigation of readout noise in near-term quantum devices by classical post-processing based on detector tomography
Filip B. Maciejewski, Zoltán Zimborás, Michał Oszmaniec
We propose a simple scheme to reduce readout errors in experiments on quantum systems with finite number of measurement outcomes. Our method relies on performing classical post-pro…
Short time behavior of continuous time quantum walks on graphs
Balázs Endre Szigeti, Gábor Homa, Zoltán Zimborás +1
Dynamical evolution of systems with sparse Hamiltonians can always be recognized as continuous time quantum walks (CTQWs) on graphs. In this paper, we analyze the short time asympt…
Approximate recovery with locality and symmetry constraints
Cédric Bény, Zoltán Zimborás, Fernando Pastawski
Numerous quantum many-body systems are characterized by either fundamental or emergent constraints---such as gauge symmetries or parity superselection for fermions---which effectiv…
