Reducing leakage of single-qubit gates for superconducting quantum processors using analytical control pulse envelopes
Eric Hyyppä, Antti Vepsäläinen, Miha Papič +10
Improving the speed and fidelity of quantum logic gates is essential to reach quantum advantage with future quantum computers. However, fast logic gates lead to increased leakage e…
Long-distance transmon coupler with CZ gate fidelity above
Fabian Marxer, Antti Vepsäläinen, Shan W. Jolin +36
Tunable coupling of superconducting qubits has been widely studied due to its importance for isolated gate operations in scalable quantum processor architectures. Here, we demonstr…
Unimon qubit
Eric Hyyppä, Suman Kundu, Chun Fai Chan +22
Superconducting qubits are one of the most promising candidates to implement quantum computers. The superiority of superconducting quantum computers over any classical device in si…
Recent Developments in Quantum-Circuit Refrigeration
Timm Fabian Mörstedt, Arto Viitanen, Vasilii Vadimov +7
We review the recent progress in direct active cooling of the quantum-electric degrees freedom in engineered circuits, or quantum-circuit refrigeration. In 2017, the invention of a…
