Native multi-qubit gates on a single-junction unimon circuit
Sasu Tuohino, Mikko Möttönen, Matti Silveri
Quantum processors with native multi-qubit gates may offer very efficient implementations of near-term quantum algorithms on noisy hardware. Here, we introduce the multiunimon, a s…
Dissipation and noise in strongly driven Josephson junctions
Vasilii Vadimov, Yoshiki Sunada, Mikko Möttönen
In circuit quantum electrodynamical systems, the quasiparticle-related losses in Josephson junctions are suppressed due to the gap in the superconducting density of states which is…
Low-characteristic-impedance superconducting tadpole resonators in the sub-gigahertz regime
Miika Rasola, Samuel Klaver, Jian Ma +4
We demonstrate a simple and versatile resonator design based on a short strip of a typical coplanar waveguide shorted at one end to the ground and shunted at the other end with a l…
Methods to achieve near-millisecond energy relaxation and dephasing times for a superconducting transmon qubit
Mikko Tuokkola, Yoshiki Sunada, Heidi Kivijärvi +6
Superconducting qubits are one of the most promising physical systems for implementing quantum computers. However, executing quantum algorithms of practical computational advantage…
Correlation measurement of propagating microwave photons at millikelvin
Aarne Keränen, Qi-Ming Chen, András Gunyhó +5
Microwave photons are important carriers of quantum information in many promising platforms for quantum computing. They can be routinely generated, controlled, and teleported in ex…
Autonomous Quantum Heat Engine Based on Non-Markovian Dynamics of an Optomechanical Hamiltonian
Miika Rasola, Mikko Möttönen
We propose a recipe for demonstrating an autonomous quantum heat engine where the working fluid consists of a harmonic oscillator, the frequency of which is tuned by a driving mode…
