Graph-theoretic approach to dimension witnessing

2020 · New Journal of Physics

Abstract A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measurements, this problem can be addressed using only the …

Teleportation with embezzling catalysts

2024 · Communications Physics

Quantum teleportation is the process of transferring quantum information using classical communication and pre-shared entanglement. This process can benefit from the use of catalysts, which are ancillary entangled states that can enhance teleportation without being …
