Searching for Quantum Effects in the Brain: A Bell-Type Test for Nonclassical Latent Representations in Autoencoders
I. K. Kominis, C. Xie, S. Li +2
Whether neural information processing is entirely classical or involves quantum-mechanical elements remains an open question. Here we propose a model-agnostic, information-theoreti…
Improved sensing with a single qubit
P. Sekatski, M. Skotiniotis, W. Dür
We consider quantum metrology with arbitrary prior knowledge of the parameter. We demonstrate that a single sensing two-level system can act as a virtual multi-level system that of…
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…
Quantum metrology for the Ising Hamiltonian with transverse magnetic field
M. Skotiniotis, P. Sekatski, W. Dür
We consider quantum metrology for unitary evolutions generated by parameter-dependent Hamiltonians. We focus on the unitary evolutions generated by the Ising Hamiltonian that descr…
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…
Optimal quantum states for frequency estimation
F. Fröwis, M. Skotiniotis, B. Kraus +1
We investigate different quantum parameter estimation scenarios in the presence of noise, and identify optimal probe states. For frequency estimation of local Hamiltonians with dep…
Improved quantum metrology using quantum error-correction
W. Dür, M. Skotiniotis, F. Fröwis +1
We consider quantum metrology in noisy environments, where the effect of noise and decoherence limits the achievable gain in precision by quantum entanglement. We show that by usin…
Quantum frameness for Charge-Parity-Time inversion symmetry
Michael Skotiniotis, Borzu Toloui, Ian T. Durham +1
We develop a theory of charge-parity-time (CPT) frameness resources to circumvent CPT-superselection. We construct and quantify such resources for spin~0, , 1, and Maj…
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…
Alignment of reference frames and an operational interpretation for the G-asymmetry
Michael Skotiniotis, Gilad Gour
We determine the quantum states and measurements that optimize the accessible information in a reference frame alignment protocol associated with the groups U(1), corresponding to…
Quantum frameness for Charge-Parity-Time (CPT) inversion symmetry
Michael Skotiniotis, Ian T. Durham, Borzu Toloui +1
We develop a charge-parity-time (CPT) frameness resource theory to circumvent CPT- superselection. We construct and quantify such resources for spins 0, 1/2, and 1 and for Majorana…
On the epistemic view of quantum states
Michael Skotiniotis, Aidan Roy, Barry C. Sanders
We investigate the strengths and limitations of the Spekkens toy model, which is a local hidden variable model that replicates many important properties of quantum dynamics. First,…
