Spin Entanglement Witness for Quantum Gravity.

Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. However, the lack of empirical evidence has lead to a debate on whether gravity is a quantum entity. Despite varied proposed probes for quantum gravity, it is fair to say that there are no feasible ideas yet to test its quantum coherent behavior directly in a laboratory experiment. Here...

Material witness: quantum writ large.

430 nature materials | VOL 7 | JUNE 2008 | www.nature.com/naturematerials salts — the charged material causes the reduction of Cu2+ ions to Cu metal and the latter is deposited on the electrode (Fig. 1b). By analysis of the product, the charge density is estimated to be similar to that found in the previous experiment, around 7 × 1014 cm–2. Further electrochemical reactions were possible — incl...

The witness set of coexistence of quantum effects and its preservers

One of unsolved problems in quantum measurement theory is to characterize coexistence of quantum effects. In this paper, applying positive operator matrix theory, we give a mathematical characterization of the witness set of coexistence of quantum effects and obtain a series of properties of coexistence. We also devote to characterizing bijective morphisms on quantum effects leaving the witness...

Witness-Indistinguishability Against Quantum Adversaries

Proof systems are a central concept in complexity theory and cryptography. Zero-knowledge and witnessindistinguishability are useful security properties of proof systems. Considering the increased power of quantum computation, it comes as a natural question to understand what happens to these security properties when quantum computation becomes feasible. Zero-knowledge [GMR89] is the security p...
