Many Copies May Be Required for Entanglement Distillation

Many copies may be required for entanglement distillation

A mixed quantum state ρ shared between two parties is said to be distillable if, by means of a protocol involving only local quantum operations and classical communication, the two parties can transform some number of copies of ρ into a single shared pair of qubits having high fidelity with the maximally entangled state |φ+〉 = (|00〉 + |11〉)/ √ 2. In this paper it is proved that there exist stat...

Publication Ethics: Many Facets, Collaboration Required

Sir, the recent publication on “Publication Ethics” is very interesting (1). The article by Fazly Bazzaz and Sadeghi demonstrated many interesting cases                   of misconducts. Indeed, the misconducts can be seen  in many ways. As mentioned in the present publication, both author and editor can perform publication misconducts. Nevertheless, the problem has many more facets. Sometimes,...

AdipoRon may be benefit for atherosclerosis prevention

Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...

Distillation and bound entanglement

Renormalising entanglement distillation

It has long been noted in the field of quantum information science that entanglement constitutes the key resource in various information processing and specifically communication tasks [1]. Secure quantum key distribution necessarily relies on entanglement, even in a sense in prepare and measure schemes [2–4]. One of the main efforts in quantum information science has therefore been directed to...
