Violations of a Leggett-Garg inequality without signaling for a photonic qutrit probed with ambiguous measurements

2018 · Physical Review A

We realize a quantum three-level system with photons distributed among three different spatial and polarization modes. Ambiguous measurements of the state of the qutrit are realized by blocking one out for the three modes at …

Quantum image classifier with single photons

2020 · arXiv (Cornell University)

Machine learning, with promising applications in quantum computation, has been introduced to a variety of quantum mechanical platforms, where its interplay with quantum physics offers exciting prospects toward quantum advantages. A central difficulty, however, lies …

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 …
