CQT Online Talks - Series: Colloquium
Speakers: Barry C. Sanders, University of Calgary
Abstract: We show that PT Symmetry is explained within our framework of time-dependent Hilbert-space inner product, which we show is equivalent to quantum-channel evolution. Despite unobservability of inner product, we show that a changing inner product is discernible and include a qubit example, which we show is simulatable by unitary evolution of a qutrit. Furthermore, we prove that this changing inner product confers no advantage for quantum computing.
