Decoherence assisted spin squeezing generation in superposition of tripartite GHZ and W states
Kapil K. Sharma, Swaroop Ganguly
In the present paper, we study spin squeezing under decoherence in the superposition of tripartite maximally entangled GHZ and W states. Here we use amplitude damping, phase dampin…

The Avian Compass can be Sensitive even without Sustained Quantum Coherence
Rakshit Jain, Vishvendra Singh Poonia, Kasturi Saha +2
Theoretical studies indicating the presence of long-lived coherence in the radical pair system have engendered questions about the utilitarian role of sustained coherence in the av…
