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…

Passive leakage removal unit based on a disordered transmon array
Gonzalo Martín-Vázquez, Taneli Tolppanen, Matti Silveri
Leakage out from the qubit subspace compromises standard quantum error correction protocols and is a challenge for practical quantum computing. We propose a passive leakage removal…

Phase transitions induced by standard and predetermined measurements in transmon arrays
Gonzalo Martín-Vázquez, Taneli Tolppanen, Matti Silveri
The confluence of unitary dynamics and non-unitary measurements gives rise to intriguing and relevant phenomena, generally referred to as measurement-induced phase transitions. The…
