Building on this platform, i will be able to demonstrate for the first time the emergence of coherent, non-local superconducting states bound to the entire device similarly to the kitaev chain model of topological superconductivity.to demonstrate quantum coherence of the chain, we will build the first andreev molecule quantum bit, which, while not topologically protected, will already combine advantages of superconducting and semiconductor qubits.
As the representative entity for this project, NEC is developing new quantum devices to overcome the issues of quantum coherence and integration(4).
Debates about the applicability of the wave function formalism in quantum mechanics as well as the relevance of quantum coherence for the information processing in the brain in various regions like visual cortex, auditory regions, olfactory bulbs etc.
Quantum coherence - the fragile state during which particles are in superposition - lasts for only a fraction of a second before the whole system decoheres, which is a phenomenon that marks the transition from the realm of quantum to classical mechanics.
He's been working on modeling how quantum coherence plays a role In this process.
Once the team engineered the viruses, they were able to use laser spectroscopy and dynamical modeling to watch the light-harvesting process in action, and to demonstrate that the new viruses were indeed making use of quantum coherence to enhance the transport of excitons.

When the sample was held at this cryogenic temperature, the nuclear spins of about 37 percent of the ions - a typical benchmark to measure quantum coherence - remained in their superposition state for three hours.
Obviously, the impact would be enormous if an isotropic and homogeneous material of simultaneously negative permittivity and permeability can be realized by using new scenarios such as quantum optical approach [17-20], in which photonic resonance and quantum coherence are involved [21-23].
