Measurements with randomly chosen settings determine many important properties of
quantum states without the need for a shared reference frame or calibration. They naturally …

Quantum entanglement, a fundamental aspect of quantum mechanics, has captured
significant attention in the era of quantum information science. In multipartite quantum …

Generic many-body systems coupled to an environment lose their quantum entanglement
due to decoherence and evolve to a mixed state with only classical correlations. Here, we …

We show that the proof of the generalised quantum Stein's lemma [Brandão & Plenio,
Commun. Math. Phys. 295, 791 (2010)] is not correct due to a gap in the argument leading to …

What is" topological" about topological quantum states? How many types of topological
quantum phases are there? What is a zero-energy Majorana mode, how can it be realized in …

The problem of finding efficient decompositions of multiqubit gates is of importance for
quantum computing, especially, in application to existing noisy intermediate-scale quantum …

Equioverlapping measurements, as a natural class of quantum measurements with the
appealing property of equal overlap between any pair of measurement operators …

The use of multilevel information carriers, also known as qudits, is a promising path for
exploring scalability of quantum computing devices. Here we present a proof-of-principle …

We present new bounds on the existence of general quantum maximum distance separable
codes (QMDS): the length $ n $ of all QMDS codes with local dimension $ D $ and distance …

Qubits, which are the quantum counterparts of classical bits, are used as basic information
units for quantum information processing, whereas underlying physical information carriers …
