Quantum 5, 482 (2021). https://doi.org/10.22331/q-2021-06-24-482 The new bound on quantum speed limit (in terms of relative purity) is derived by applying the original Mandelstam-Tamm one to the evolution in the space of Hilbert-Schmidt operators acting […]
Quantum 5, 481 (2021). https://doi.org/10.22331/q-2021-06-24-481 Inspired by recent progress in quantum algorithms for ordinary and partial differential equations, we study quantum algorithms for stochastic differential equations (SDEs). Firstly we provide a quantum algorithm that gives […]
Quantum 5, 480 (2021). https://doi.org/10.22331/q-2021-06-24-480 Quantum resource theory under different classes of quantum operations advances multiperspective understandings of inherent quantum-mechanical properties, such as quantum coherence and quantum entanglement. We establish hierarchies of different operations for […]
Quantum 5, 479 (2021). https://doi.org/10.22331/q-2021-06-17-479 There is an increasing interest in quantum algorithms for problems of integer programming and combinatorial optimization. Classical solvers for such problems employ relaxations, which replace binary variables with continuous ones, […]
Quantum 5, 478 (2021). https://doi.org/10.22331/q-2021-06-17-478 Quantum entanglement is a form of correlation between quantum particles that cannot be increased via local operations and classical communication. It has therefore been proposed that an increment of quantum […]
Quantum 5, 477 (2021). https://doi.org/10.22331/q-2021-06-17-477 In this paper, we introduce optimal versions of a multi-port based teleportation scheme allowing to send a large amount of quantum information. We fully characterise probabilistic and deterministic case by […]
Quantum 5, 476 (2021). https://doi.org/10.22331/q-2021-06-15-476 One of the basic distinctions between classical and quantum mechanics is the existence of fundamentally incompatible quantities. Such quantities are present on all levels of quantum objects: states, measurements, quantum […]
Quantum 5, 475 (2021). https://doi.org/10.22331/q-2021-06-15-475 A Physical Unclonable Function (PUF) is a device with unique behaviour that is hard to clone hence providing a secure fingerprint. A variety of PUF structures and PUF-based applications have […]
Quantum 5, 474 (2021). https://doi.org/10.22331/q-2021-06-10-474 At the dawn of Quantum Physics, Wigner and Weisskopf obtained a full analytical description (a $textit{photon portrait}$) of the emission of a single photon by a two-level system, using the […]
Quantum 5, 473 (2021). https://doi.org/10.22331/q-2021-06-10-473 Recently a new class of quantum algorithms that are based on the quantum computation of the connected moment expansion has been reported to find the ground and excited state energies. […]
