Approximate encoding of quantum states using shallow circuits
npj Quantum InformationQuantum algorithms and simulations often require the preparation of complex states through sequences of 2-qubit gates. For a generic quantum state, the number of required gates grows exponentially with the number of qubits, becoming unfeasible on near ...

Entanglement and symmetries in many-body quantum systems [PDF]
, 2022 As Schroedinger already recognised one century ago, entanglement is at the core of quantum mechanics. Nowadays it turns out to be the fundamental notion behind many quantum phenomena, from quantum algorithms to gravity, passing by critical phenomena and ...

Multi-Photon Entanglement [PDF]
, 2009 Major efforts in quantum information science are devoted to the development of methods that are superior to the one of classical information processing, for example the quantum computer or quantum simulations.

Detecting High-Dimensional Entanglement in Cold-Atom Quantum Simulators
PRX Quantum, 2023 Quantum entanglement has been identified as a crucial concept underlying many intriguing phenomena in condensed matter systems, such as topological phases or many-body localization.

Physical Review Research, 2023 Entanglement is known to decay even in isolated systems, an effect attributed to spontaneous emission. This fragility of entanglement can be exacerbated by entanglement sudden death (ESD), where entanglement drops to zero abruptly within a finite time ...

Entanglement Exchange and Bohmian Mechanics [PDF]
, 2009 This paper analyses the phenomenon of entanglement exchange in Bohm's pilot wave interpretation of quantum mechanics. The interesting feature of the phenomenon is that systems become entangled without causal interaction; hence it is a useful situation ...

Coherence of assistance and assisted maximally coherent states
Scientific Reports, 2021 Coherence and entanglement are fundamental concepts in resource theory. The coherence (entanglement) of assistance is the coherence (entanglement) that can be extracted assisted by another party with local measurement and classical communication.
