Constructing mehod of 2-EPP with different quantum error correcting
... In this paper, we proposed a method to construct a 2EPP which consists of different quantum error correcting codes and by simulations investigated the performance of the 2-EPPs for a phase-damping channel. The proposed protocol showed improved fidelity and purification rate compared with an EPP from a ...

Quantum circuits for strongly correlated quantum systems
... novel ways of looking at strongly correlated quantum manybody systems. On the one hand, a great deal of theoretical work has been done identifying the basic structure of entanglement in low-energy states of many-body Hamiltonians. This has led, for example, to new interpretations of renormalization- ...

... There is no actual function that does this, although one can think of δ(x0 −x) as a sort of limit of ordinary functions that vanish when x0 − x is not very close to 0 but are very big when x0 − x is very close to 0, with the area under the graph of δ(x0 − x) equal to 1. The precise way to think of i ...

We infer the accidental coincidence rates from the corresponding single rates, knowing the widths of the windows. This method ...
