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…
C2|Q>: A Robust Framework for Bridging Classical and Quantum Software Development -- RCR Report
Boshuai Ye, Arif Ali Khan, Teemu Pihkakoski +4
This is the Replicated Computational Results (RCR) Report for the paper C2|Q>: A Robust Framework for Bridging Classical and Quantum Software Development. The paper introduces a mo…
Gate-Based Microwave Quantum Repeater Via Grid-State Encoding
Hany Khalifa, Matti Silveri
In autonomous quantum error correction the lifetime of a logical bosonic qubit can be extended beyond its physical constituents without feedback measurements. Leveraging autonomous…
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…
