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…
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…
Towards a benchmark for quantum computers based on an iterated post-selective protocol
Adrian Ortega, Orsolya Kálmán, Tamás Kiss
Applying post selection in each step of an iterated protocol leads to sensitive quantum dynamics that may be utilized to test and benchmark current quantum computers. An example of…
Universal, unambiguous concentration and distillation of Bell pairs
Orsolya Kálmán, Aurél Gábris, Igor Jex +1
The ability of preparing perfect Bell pairs with a practical scheme is of great relevance for quantum communication as well as distributed quantum computing. We propose a scheme wh…
