Finding Traps in Non-linear Spin Arrays
Marcin Wiesniak, Marcin Markiewicz
Precise knowledge of the Hamiltonian of a system is a key to many of its applications. Tasks such state transfer or quantum computation have been well studied with a linear chain,…
One-Qubit and Two-Qubit Codes in Noisy State Transfer
Marcin Markiewicz, Marcin Wieśniak
Quantum state transfer is a procedure, which allows to exchange quantum information between stationary qubit systems. It is anticipated that the transfer will find applications in…
Experimental filtering of two-, four-, and six-photon singlets from single PDC source
Magnus Radmark, Marcin Wiesniak, Marek Zukowski +1
Invariant entangled states remain unchanged under simultaneous identical unitary transformations of all their subsystems. We experimentally generate and characterize such invariant…
Interference contrast in multi-source few photon optics
Wieslaw Laskowski, Marcin Wiesniak, Marek Zukowski +2
Many recent experiments employ several parametric down conversion (PDC) sources to get multiphoton interference. Such interference has applications in quantum information. We study…
Perfect State Transfer without State Initialization and Remote Collaboration
Marcin Markiewicz, Marcin Wiesniak
We present a perfect state transfer protocol via a qubit chain with the evolution governed by the Hamiltonian. In contrast to the recent protocol announced in [Phys. Rev. Lett…
