Exact convergence times for generation of random bipartite entanglement
Marko Znidaric
We calculate exact convergence times to reach random bipartite entanglement for various random protocols. The eigenproblem of a Markovian chain governing the process is mapped to a…
Complexity of thermal states in quantum spin chains
Marko Znidaric, Tomaz Prosen, Iztok Pizorn
We study quantum correlations and complexity of simulation, characterized by quantum mutual information and entanglement entropy in operator space respectively, for thermal states…
Initial-state randomness as a universal source of decoherence
Marko Znidaric
We study time evolution of entanglement between two qubits, which are part of a larger system, after starting from a random initial product state. We show that, due to randomness i…
How many CNOT gates does it take to generate a three-qubit state ?
Marko Znidaric, Olivier Giraud, Bertrand Georgeot
The number of two-qubit gates required to transform deterministically a three-qubit pure quantum state into another is discussed. We show that any state can be prepared from a prod…
Detecting entanglement of random states with an entanglement witness
Marko Znidaric, Tomaz Prosen, Giuliano Benenti +1
The entanglement content of high-dimensional random pure states is almost maximal, nevertheless, we show that, due to the complexity of such states, the detection of their entangle…
Many body localization in Heisenberg XXZ magnet in a random field
Marko Znidaric, Tomaz Prosen, Peter Prelovsek
We numerically investigate Heisenberg XXZ spin-1/2 chain in a spatially random static magnetic field. We find that tDMRG simulations of time evolution can be performed efficiently,…
