Relations between different definitions of the quantum Wasserstein distance

Géza Tóth, József Pitrik

The quantum Wasserstein distances defined by Golse, Mouhot, Paul, and Caglioti and by De Palma and Trevisan coincide for qubits when a single operator appears in the cost function.…

General method for obtaining the energy minimum of spin Hamiltonians for separable states

Géza Tóth, József Pitrik

We present a general method to determine the energy minimum of spin Hamiltonians over separable states when the single-particle reduced density matrices are fixed. For ferromagneti…

Differential magnetometry with partially flipped Dicke states

Iagoba Apellaniz, Manuel Gessner, Géza Tóth

We study magnetometry of gradients and homogeneous background fields along the three orthogonal directions using two spatially separated spin ensembles. We derive trade-off relatio…

Quantum Wasserstein distance and its relation to several types of fidelities

Géza Tóth, József Pitrik

We consider several definitions of the quantum Wasserstein distance based on an optimization over general bipartite quantum states with given marginals. Then, we examine the quanti…

Hong-Ou-Mandel interference of more than 10 indistinguishable atoms

Martin Quensen, Mareike Hetzel, Luis Santos +4

When two indistinguishable bosons interfere at a beam splitter, they both exit through the same output port. This foundational quantum-mechanical phenomenon, known as the Hong-Ou-M…

Reference-frame-independent quantum metrology

Satoya Imai, Otfried Gühne, Géza Tóth

How can we perform a metrological task if only limited control over a quantum system is given? Here, we present systematic methods for conducting nonlinear quantum metrology in sce…

Alternatives of entanglement depth and metrological entanglement criteria

Szilárd Szalay, Géza Tóth

We work out the general theory of one-parameter families of partial entanglement properties and the resulting entanglement depth-like quantities. Special cases of these are the dep…
