Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
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.…
Finding the ground state of the Hubbard model by variational methods on a quantum computer with gate errors
Jan-Michael Reiner, Frank Wilhelm-Mauch, Gerd Schön +1
A key goal of digital quantum computing is the simulation of fermionic systems such as molecules or the Hubbard model. Unfortunately, for present and near-future quantum computers…
Effects of gate errors in digital quantum simulations of fermionic systems
Jan-Michael Reiner, Sebastian Zanker, Iris Schwenk +4
Digital quantum simulations offer exciting perspectives for the study of fermionic systems such as molecules or lattice models. However, with quantum error correction still being o…
