Chifeng University Team Maps Qubit Sync Window Duration
Synchronization window durations diminish quickly as outer qubit couplings increase, yet become surprisingly insensitive to changes in central qubit coupling, a departure from previous analyses focused solely on entanglement. This work reveals how three superconducting qubits coupled via microwave cavities achieve recurring moments of near identical quantum states, quantified by trace distance measurements. Understanding these synchronized behaviours offers new ways to characterise complex interactions within potential future quantum technologies.
Multiple superconducting qubits can work together in a coordinated way, opening new possibilities for complex quantum computations. Studying three such qubits linked by a shared microwave field revealed recurring periods where pairs of qubits exhibited highly similar behaviour; this synchronization was quantified using measurements of their individual quantum properties. The interaction details how multiple superconducting quantum bits (qubits) interact via shared microwave fields and examines when pairs exhibit similar behaviour, termed pairwise…
