Using an additional entangled degree of freedom as an ancilla space, it has been shown that it is possible to perform efficient Bell-state measurements. We briefly review these results and present a novel deterministic quantum key distribution protocol based on Bell-state measurements of hyperentangled photons. In addition, we propose a scheme for a probabilistic controlled-not gate which operates with a 50% success probability. We also show that despite its probabilistic nature, the controlled-not gate can be used for an efficient, nonlocal demonstration of the Deutsch algorithm using two separate photons.<\/jats:p>","DOI":"10.26421\/qic6.4-5-3","type":"journal-article","created":{"date-parts":[[2021,3,11]],"date-time":"2021-03-11T02:06:12Z","timestamp":1615428372000},"page":"336-350","source":"Crossref","is-referenced-by-count":4,"title":["Quantum information processing with hyperentangled photon states"],"prefix":"10.26421","volume":"6","author":[{"given":"S.
