“…Selanjutnya, Alice melakukan pengukuran dengan basis 2 σ x dan misi teleportasi selesai. Tampak bahwa pengukur pada Persamaan (9) lebih rumit dengan tingkat akurasi lebih rendah dibanding tingkat akurasi dari pengukur pada Persamaan (5). Meskipun demikian kanal tiga kubit ini memungkinkan kehadiran seseorang sebagai pengontrol -sebut saja Charlie-dalam teleportasi dan teleportasi dapat terjadi jika ketiganya berinteraksi [3].…”

“…Kajian teoritis dapat berupa perluasan kanal tidak lagi pasangan dua partikel tetapi tiga [3] maupun informasi tidak lagi dari partikel tunggal tetapi dua partikel via kanal empat partikel [4]. Teleportasi hanya dapat terjadi via kanal terbelit [1,5] dan mengetahui sifat keterbelitan kubit tinggi menjadi perlu dan telah diakukan [6].…”

We generalized the maximally entangled Hamiltonian of the isotropic Heisenberg XX model with two spin-1/2 particles to the case of non-maximal entanglement parametrized by the degree of non-maximality 0 < n < 1. The thermal concurrence as the function of the degree of non-maximality in the entanglement at different values of the exchange parameter is calculated. We analyzed the efficiencyof the quantum Otto engine for different scenarios of exchange parameter regimes and the degree of maximal entanglement between the spin states. We showed that it is possible to run the quantum Otto engine using non-maximally entangled states and achieve higher efficiencies by controlling the exchange parameter value with respect to a critical value Jc and this feature also depends on the degree of non-maximal entanglement n 6= 1. This result may be useful for harnessing the non-maximal entanglement in quantum heat engine for optimizing the operation of quantum devices interacting with heat bath or environment.
