Web21 de nov. de 2024 · A possible mechanism is the so-called communication-through-coherence (CTC), which posits that phase coherence would be the neural substrate to achieve inter-regional information exchange ( Fries, 2005, Fries, 2015 ). However, while the CTC only considers the coupling between oscillations of the same frequency, more … Web1 de out. de 2024 · Add a comment. 71. Coupling - A measure of how much a module (package, class, method) relies on other modules. It is desirable to reduce coupling, or …
WebThe high thermal exchange performance of QVMs arises from the strong mutual coherence effect between QVMs and other modes. The spectral analysis further demonstrates that this strong mutual coherence is resulting from the strong mode shape coupling (i.e., high generalized group velocity) and the high mutual energy gain (i.e., high generalized … WebRecent experiments have demonstrated record coherence times for low-frequency fluxonium qubits. Here, we propose a galvanic coupling scheme with flux-Tunable XX coupling. To implement a high-fidelity entangling iSWAP gate, we modulate the strength of this coupling and devise variable-Time identity gates to synchronize required single …
Web28 de nov. de 2014 · We introduce a superconducting qubit architecture that combines high-coherence qubits and tunable qubit-qubit coupling. With the ability to set the coupling to zero, we demonstrate that this architecture is protected from the frequency crowding problems that arise from fixed coupling. More important … Web22 de abr. de 2024 · In the current device, the single pillar in the enclosure is not expected to have contributed to the observed high coherence and low cross-talk results due to …
WebLow coupling, loose coupling có nghĩa là các component ít phụ thuộc vào nhau, sự thay đổi trong component này ít khi, hoặc không ảnh hưởng đến component kia. Ngược lại, high coupling và tight coupling cho thấy các component phụ thuộc nhiều vào nhau, khi thay đổi 1 component thì các component kia đều bị ảnh hưởng và có khả năng ...
Web25 de nov. de 2024 · Abstract. We report superconducting fluxonium qubits with coherence times largely limited by energy relaxation and reproducibly satisfying T 2 > 100 μs ( T 2 >400 μs in one device). Moreover, given the state-of-the-art values of the surface loss tangent and the 1/f flux-noise amplitude, the coherence time can be further improved beyond 1 ms. shan youth powerWeb5 de dez. de 2024 · Metrics.
