Multi-Boundary Many-Body Quantum Teleportation
Tal Schwartzman, Antonio F. Rotundo, Raz Monsonego +1
Unlike standard quantum teleportation, many-body teleportation uses scrambling to transmit quantum information. In this protocol, initially localized information spreads over many…
Imaginary time evolution and ground state preparation using unitary multi-copy protocols
Tal Schwartzman, Torsten V. Zache, Hannes Pichler +1
Efficient low-energy state preparation is a key objective in quantum computation and quantum simulation. Quantum imaginary-time evolution replaces real-time dynamics with imaginary…
The complexity of entanglement embezzlement
Tal Schwartzman
Embezzlement of entanglement is the counterintuitive process in which entanglement is extracted from a resource system using local unitary operations, with almost no detectable cha…
Entanglement on curved hypersurfaces: A field-discretizer approach
Tal Schwartzman, Benni Reznik
We propose a covariant scheme for measuring entanglement on general hypersurfaces in relativistic quantum field theory. For that, we introduce an auxiliary relativistic field, 'the…
