Macroscopic entanglement in Quantum Computation
Akihisa Ukena, Akira Shimizu
We investigate macroscopic entanglement of quantum states in quantum computers, where we say a quantum state is entangled macroscopically if the state has superposition of macrosco…

Detection of Macroscopic Entanglement by Correlation of Local Observables
Akira Shimizu, Tomoyuki Morimae
We propose a correlation of local observables on many sites in macroscopic quantum systems. By measuring the correlation one can detect, if any, superposition of macroscopically di…
