Ergodic dynamics in iterated quantum protocols
Attila Portik, Orsolya Kálmán, Tamás Kiss
We study measurement-induced nonlinear dynamics generated by an iterated quantum protocol combining an entangling gate, a single-qubit rotation, and post-selection. For pure single…
The EU Quantum Flagship's Key Performance Indicators for Quantum Computing
Zoltán Zimborás, Attila Portik, David Aguirre +10
As quantum processors continue to scale in size and complexity, the need for well-defined, reproducible, and technology-agnostic performance metrics becomes increasingly critical.…
Clifford Volume and Free Fermion Volume: Complementary Scalable Benchmarks for Quantum Computers
Attila Portik, Orsolya Kálmán, Thomas Monz +1
As quantum computing advances toward the late-NISQ and early fault-tolerant eras, scalable and platform-independent benchmarks are essential for quantifying computational capacity…
Practical scheme for efficient distillation of GHZ states
Áron Rozgonyi, Gábor Széchenyi, Orsolya Kálmán +1
We develop an efficient local operation and classical communication (LOCC) scheme for the distillation of Greenberger-Horne-Zeilinger (GHZ) states from tripartite systems subjected…
Myths around quantum computation before full fault tolerance: What no-go theorems rule out and what they don't
Zoltán Zimborás, Bálint Koczor, Zoë Holmes +19
In this perspective article, we revisit and critically evaluate prevailing viewpoints on the capabilities and limitations of near-term quantum computing and its potential transitio…
