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…
Leakage Mobility and Passive Leakage Removal in Transmons with Tunable Couplers
Taneli Tolppanen, Gonzalo Martín-Vázquez, Sasu Tuohino +1
Qubit leakage is a noticeable source of errors for quantum computing. In quantum processors, leakage excitations traveling between qubits generate correlated errors and perturb gat…
Perturbative Analysis of Dark State Dynamics in Weakly Anharmonic Photon-Emitter Pairs
Christopher Campbell, Matti Silveri
Dark states are excited quantum states that decouple from their environment in such a way that they do not emit or absorb external photons. These states are found in a variety of d…
