Embedded quantum-error correction and controlled-phase gate for molecular spin qubits

2021 · AIP Advances

A scalable architecture for quantum computing requires logical units supporting quantum-error correction. In this respect, magnetic molecules are particularly promising, since they allow one to define logical qubits with embedded quantum-error correction by exploiting multiple …

Parrondo’s Paradox for Discrete-Time Quantum Walks in Momentum Space

2022 · Fluctuation and Noise Letters

We investigate the possibility of implementing a sequence of quantum walks whose probability distributions give an overall positive winning probability, while it is negative for the single walks (Parrondo’s paradox). In particular, we have in …
