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…

Mutual Information is not a Reliable Measure for Variations in Total Correlations
S. Alipour, S. Tuohino, A. T. Rezakhani +1
Correlations disguised in various forms underlie a host of important phenomena in classical and quantum systems, such as information and energy exchanges. The quantum mutual inform…
