The complete phase diagram of detailed-balanced Gibbs samplers for the mean-field Heisenberg model
Levente Raikovich, József Mák, Csaba Czabán +1
We study the spectral gap of recently discovered families of KMS-detailed-balanced Gibbs-sampler Lindbladians for the mean-field Heisenberg model on spins. We show that the spe…
Repetition-code-based readout error detection and correction across hardware platforms and generations
Csaba Czabán, Orsolya Kálmán, Sergey N. Filippov +1
Readout errors are one of the dominant sources of noise in current quantum processors, limiting both expectation-value estimation and sampling-based applications. Since they affect…
Hybrid Quantum-Classical Reinforcement Learning in Latent Observation Spaces
Dániel T. R. Nagy, Csaba Czabán, Bence Bakó +3
Recent progress in quantum machine learning has sparked interest in using quantum methods to tackle classical control problems via quantum reinforcement learning. However, the clas…
Suppressing photon detection errors in nondeterministic state preparation
Csaba Czabán, Zoltán Kolarovszki, Márton Karácsony +1
Photonic quantum computing has recently emerged as a promising candidate for fault-tolerant quantum computing by photonic qubits. These protocols make use of nondeterministic gates…
