Compressed quantum metrology for the Ising Hamiltonian
W. L. Boyajian, M. Skotiniotis, W. Dür +1
We show how quantum metrology protocols that seek to estimate the parameters of a Hamiltonian that exhibits a quantum phase transition can be efficiently simulated on an exponentia…
Deterministic superreplication of one-parameter unitary transformations
W. Dür, P. Sekatski, M. Skotiniotis
We show that one can deterministically generate out of copies of an unknown unitary operation up to almost perfect copies. The result holds for all operations generated b…
Quantum Resource Theory for Charge-Parity-Time Inversion
Michael Skotiniotis, Borzu Toloui, Ian T. Durham +1
We develop a complete resource theory of charge-parity-time (CPT) inversion symmetry for both massive and massless relativistic particles of arbitrary spin. We show that a unitary…
Efficient quantum communication under collective noise
Michael Skotiniotis, Wolfgang Dür, Barbara Kraus
We introduce a new quantum communication protocol for the transmission of quantum information under collective noise. Our protocol utilizes a decoherence-free subspace in such a wa…
