Practical gates by Majorana fermion motion
Yuri D. Lensky, Bryce Kobrin, Kostyantyn Kechedzhi +1
Quantum error correction protocols protect against local errors by storing logical information non-locally. This poses a challenge: how to design efficient logical gates on the non…
Observation of disorder-free localization using a (2+1)D lattice gauge theory on a quantum processor
Gaurav Gyawali, Shashwat Kumar, Yuri D. Lensky +219
Disorder-induced phenomena in quantum many-body systems pose significant challenges for analytical methods and numerical simulations at relevant time and system scales. To reduce t…
Correlated Error Bursts in a Gap-Engineered Superconducting Qubit Array
Vladislav D. Kurilovich, Gabrielle Roberts, Leigh S. Martin +17
One of the roadblocks towards the implementation of a fault-tolerant superconducting quantum processor is impacts of ionizing radiation with the qubit substrate. Such impacts tempo…
Quasiparticle-induced decoherence of a driven superconducting qubit
Mykola Kishmar, Pavel D. Kurilovich, Andrey Klots +3
We develop a theory for two quasiparticle-induced decoherence mechanisms of a driven superconducting qubit. In the first mechanism, an existing quasiparticle (QP) tunnels across th…
Constructive interference at the edge of quantum ergodic dynamics
Dmitry A. Abanin, Rajeev Acharya, Laleh Aghababaie-Beni +262
Quantum observables in the form of few-point correlators are the key to characterizing the dynamics of quantum many-body systems. In dynamics with fast entanglement generation, qua…
Observable Measurement-Induced Transitions
Aleksei Khindanov, Igor L. Aleiner, Lara Faoro +1
One of the main postulates of quantum mechanics is that measurements destroy quantum coherence (wave function collapse). Recently it was discovered that in a many-body system dilut…
